Measurement of voltage and the voltage with CompactDAQ display?
OK, I just got my CompactDAQ hooked up with two modules (9225, 9239) and am able to simple single-phase voltage (120 VAC)... I connected an indicator, and it gives me shooting random sine wave values and what I'm looking for a simple voltage reading. MAX and the DAQ assistant both work very well to the configuration task and I can see the signal in there.
I dug through the DAQmx, watched functions in the knowledge base and have searched here without any real results. I also downloaded the EPM resource kit, but it's tools for further on the road... It seems to me that this should be simple crazy, but maybe I go too hard or just looking is not in the right place? I would greatly appreciate a point in the right direction!
Thank you!
Chad
With the help of... Windows XP (SP3), LabVIEW 2009, cDAQ-9174, 9225, 9239.
Chad,
When you say "simple voltage readout" are you referring to the effective voltage of the AC signal? If Yes, you can use the Express VI 'Amplitude and level measures' to calculate the desired value.
Hope this helps, otherwise if specify you what you are looking for a little I will try again.

I have a new mini iPad 4. I can't delete a game called Float that gives the message waiting. The cross and the oscillation with delete option appear, but it won't when I select Remove. I don't know how it came to be. Any ideas please? Thank you.
First try a reset to see if it finishes downloading. Press and hold the home and power buttons until the Apple logo appears. Release the two buttons. Wait until the iPad tour starts on its own.
Check if you can remove the application. If not go into settings > general > use iCloud and storage > storage > storage management. Wait for the list of apps to open. See if the float is on the list. If it is delete it from there.

Hi I would like th different creative cloud buy 2, only photoshop/lightroom one and the other with all pack.is it is possible because I saw that we can only install on 2 different computers at the same time
Creative desktop cloud applications can be downloaded and installed on multiple computers, regardless of the operating system. However, the activation is limited to two machines per individual related to the composition, and you may not use the software on these devices simultaneously.
You can also see:
FAQ: Can I install Creative Cloud on several computers?
You can either sign of Creative cloud on a computer to connect to another, or as you said, buy a membership second using an AdobeID different so that you can leave, signed at on 4 computers.

I get a Script Error failed. I think it is because the domain name is on page 1 and the field with the calculation is on page 2.
The formula is just + Cash. I don't know how to tell him to look on Page 1. If I use the same domain on Page 1, the formula works so I know that this is not something in the name of the field.
It received NO response
Page1.cash should do it. If not, you can use CTRL + click to enter its name in your script.
- Select the field that you add the script.
- Scroll the design view until you can see the object whose name you need. (Is not necessary if the object is already in mode)
- Click inside the script window to place the cursor where you want the name of the other object.
- Hold down the CTRL key while clicking the object whose name you need.

5.1 Lightroom ceased to import JPEGs of iPhone. The iphone and the images will be displayed, but import said that they cannot be read. This has just begun. Even the phone, IOS and the OS.
The message 'could not be read' indicates you do not have WRITE permission on the destination folder. So, here's what you need to do
- The Lightroom Import dialog box, go to the Destination section to the right and make a note of the specified folder.
- Change the folder to something else; OR in your operating system, change the permissions on this specific file WRITE permission.

Downloaded photoshop elements 12 ok installed and activated, it started and the start screen is displayed and the application is started then stop immediately.
Repetition and crashes again. Help it does not start!
Solved! Tried everything in support documents and none of it worked. Frustration massive Adobe Chat staff who knows nothing and just told me to look at the documents of support again and again. They also gave me a phone number in Australia which has a recorde d message saying that the product is not supported! What is everything?
Finally Adobe technical support Anand called me (from when I have opened the original case of support which gave me the serial number).
Just had to rename the file SLCache in c:\program (x 86) and again the EULA and reactive. Now everything works fine. Way to hard.

HP Pavilion Elite 590uk with windows 7 64 bit.
What is the main difference between the GEForce GT420 installed and the GTS450.
I know the 429 is DDR3 and the 450 is DDR5 what - what, can I replace the 420 to 450 and how do I
Hello
There is a large performance difference and energy consumption. Look at this comparison.
The 420 is a narrow card requiring only a single slot where the 450 is a map more wide which will cover the next adjacent location. Look at the diagram for the motherboard of your PC. The GTS 450 requires a PCI-E power connector 6 pins provide the extra power for the card.
Open your PC and a few measurement in parallel with the PCI-E x 16 slot to see how long of a video card will fit. The adjacent slot on the PCI-E x 16 slot must be vacant. Look for a PCI-E power connector 6-pin.

Still not get the filtering and the SUMIF with visible cells
Hi all
I know it is a pain for you people, but I'm really stuck with this problem.
I tried to use the answers I found in the community and the User Guide, but I have to be closed to this kind of explanation.
Once again:
In the column A is a series of dates
In column B the value corresponding
In the foot of B line, I want the SumOf only the visible cells that I filtered before.
So far I have always the sum of all the lines, filtered or not.
I added another column with a True/False value and tried to use it but get the same result.
I'm pretty slow, so I guess that I'll need your help once more.
It is the sum before filtering:
And that's the sum after filtering:
I thank you for your time and patience.
Lopez
Lopez Hello,
Table filtering only affects the rows that are displayed. Hidden lines are always included in the calculations of formulas referring to them.
Your formula, = SUM (B2:B16) summarizes the content of all the B2 to B16 cells, including those that are hidden.
There are several other functions in the family of the SUM. SUM, SUMIF and SUMIF. ENS are of interest here.
SUMIF (English: SUMIF) accepts a condition and only adds the cells on the lines which is assembled as a condition.
SUMIF. ENS (English: SUMIFS) accepts several conditions and only adds the cells on the rows that meet all the conditions.
For the example stated in your post, must be the form you need:
= SUMIF. ENS(B; A; "> = 02/01/2016." A; "" < 03/01/2016 ")"
(NOT tested. The dates should be placed in two cells and these cells referenced in the formula. post a reply with any error message if the formula does not work as written).
The lines not included in the amount need not be hidden.
If the formula is inserted into column B, it must be in a line defined as a footer line using the menu item in the same position as the highlight in this screenshot:
Footer lines can be placed on foot (bottom) of a table.
Kind regards

two hard drives, one with vista and the other with XP and you want to remove second disk XP
I have a hard drive that came with my computer and vista on it, I added a second drive to my bench that has XP on it. I want to remove the second XP disc and simply use it as a storage drive, and I'm afraid that if I try and uninstall XP disc, it allows to uninstall vista of the first hard drive instead. or should I even try and uninstall it all and just delete all files? Since there is nothing in the registry for all the things on the second disc. If I uninstall XP second drive will be there remove all of that second drive? because there are a few things about this, I still want to keep. I should also mention that it is divided into three separate letters, if I do not uninstall XP I lose all three of these letters of partitioned drive? Any help on this would be greatly appreciated.
Thank you.
You can just uninstall XP. Anyway, as you say, you can remove the folder Program Files and Windows in that partition but personally I would just copy the files I need to another partition (on the hard drive where vista is installed) and the format of the old HDD.

Hello
I'm playing with a really simple WebWorks app that aims to get the geolocation of the user.
The related javascript code is:
// location related functions: function getLocation() { if (navigator.geolocation) { var options; navigator.geolocation.getCurrentPosition(geolocationSuccess, geolocationError, options); } else { alert("HTML5 geolocation is not supported."); } } function geolocationError(error) { alert("An unexpected error occurred [" + error.code + "]: " + error.message); } function geolocationSuccess(position) { //Extract information about the users current position: var time = position.timestamp; var coordinates = position.coords; //Retrieve geographic information about the GPS fix: var lat = coordinates.latitude; var lon = coordinates.longitude; displayLocation(lat, lon); } function displayLocation(latitude, longitude) { var message = "Your current location is "; document.getElementById("locationDisplay").innerHTML = message + "latitude: " + latitude + ", " + "longitude: " + longitude; }
However, the geolocation features display location Simulator 9800 information 6.0.0.227 (I put location manually of "Simulator"-> "GPS Position") and device with os 6.0 (I did turn on Javascript and allow javascript support), but it works on Simulator 9550 5.0.0.71 3.
I also find that my smart phone BlackBerry with os 6.0 browser cannot display some html5 (i.e.http://merged.ca/iphone/html5-geolocatio) demonstration sites location information
All ideas
I have a Storm 2 and a key
They respond very differently to the GPS tracks
I found sort of the problem as if you are in the open air or not
My Storm 2 have no idea where I am if I sat inside my house
My flashlight - gimme a sec - well - that failed too
My Droid knows exactly where I am, my Nokia thinks I live 250 miles
I think that we live in is too much running
Go outside (with the exception of Nokia) and you are placed with precision
Inside, we have strong signals from WiFi, compuer (s) and other things that stop at the GPS lock
Today I went to my wife, it's a connection perfect area without radio - not even a chance to pick up WiFi-
I took a taxi home - perfect connecton (maps is cool when you can tell the driver how fast he is dong
) Last night I had a meeting with the boss - once again, perfect positioning
The only thing that is different is that I'm not surrounded by radio parasite (all devices work on radio - WiFi, GPS, Bluetooth - you name it)
Then...
Just try it - walking down the street, turn over the cards, I'm positive you get a few feet away where you are
Try the same thing with radio pullution (reception, WiFi, etc.) and the GPS can't find anything
Believe me - work I am personal watercraft requires precise locations so it was annoying me as well
At least I have the solution

Hi, I'm new to blackberry. I just got a "BOLD", and some of the icons seem to be redundant. If someone could explain why I would really appreciate it. I had trouble getting the results of a search of forum so I apologize if this topic has been discussed recently.
What is the difference between 'messages' (which looks like an envelope) and the other envelope with the globe on it (which appears as [email protected])?
Can I delete one? I don't understand why there are two.
Also, why is it "medianet" and "browser"? They aren't going to the same place? What is an AT & T thing where they try to control the universe?
Thanks for your help,
KG
With the BlackBerry, you can have up to 10 "BIS" (BlackBerry Internet Service) email addresses, but also a company e-mail sent to your BlackBerry address. It is also SMS (text) messages, PIN of PIIN messages and MMS messages.
Each BIS email address gets its own icon which will appear only this e-mail by e-mail address. The Messages icon ALL E-mail addresses sent to the BlackBerry. It will also display all messages in pine and optionally show the SMS (text) messages and phone calls, and IM still active cats. But there is no icon for only PIN messages.
The fact that there is no way to separate the email from company to a simple icon is a point of contention for some users. There is a product (Empower BES Mailbox - OTA / Web $20) which will create an icon that displays only the Enterprise email. However, you can also create a saved search to display only the BES (BlackBerry Enterprise Server) email.
If you prefer using a simple icon of Messages or have separate icons for each email address is a matter of personal preference. If you have only one or two emails being sent to your BlackBerry, there is probably little difference. However, I have six accounts BIS as a BES account delivered and many prefer to have a place to look when I hear or feel that a new message has arrived.
In addition, equipped with a full QWERTY keyboard device, I'd rather be able to use the shortcut keys to access ALL the applications on my BlackBerry. In fact, I have everything I don't need (including Messages, all messaging icons, address book, calendar, Notepad, etc.) in a folder called hidden since I never need them!

Dead pixel blackBerry Smartphones and the problem with the case of my BlackBerry 9780
Hello world
Recently, I bought a BlackBerry 9780 by Vodafone Spain (23 December) and I found a few problems.
One of them is the presence of a dead pixel in the upper right and the feeling of the case a little weak in the left side that, when you touch it you can feel it creaks a bit.
I would like to know if the warranty of BlackBerry or Vodafone Spain will cover this problem or if some of the new users of this model of BlackBerry noticied some of these problems and knows how to solve this problem.
Sorry if they have problems with spelling. My usual language is Spanish .
Thank you very much.
A dead pixel is a hardware fault, and there is no miracle for her.
Check if you can get a replacement.
