read ppm
Dear all,
I have the understanding of the problem of my PXI 4072 card specification. On the specification data sheet, the accuracy of written information are common DC +/-(PPM de lecture) + PPM of range, what is this average reading PPM?
Best regards
Hello
I want to say: 'Why use if you don't understand' but I don't know your situation.
How I understand it: for continuous as in your picture 2 years after calibration tolerance is 500 ppm of reading + 50 ppm of range for the range of 1 to power.
So, if you're 500mA to measure tolerance is the 250 µA (500 ppm of 500mA) + (50 ppm of 1A) 50 µA = 300 µA

Precision in the reading of temperature PT100 and Module of NI9219
Hello
I m the temperature reading with a PT100, connected to the NI9219 Module. I put LabVIEW on mode 4 son RTD (PT100 range). I m able to read the weather temperature but I m do not know the right precision s or not. The temperature is between 25.5 and 25.8 ° C. Is this possible? I am able to do something to have more precision?
Thank you in advance,
Claudia
Hi Claudia,.
The specifications for the 9217 provide the absolute measurement accuracy Pt 100 RTD (3 and 4 sons) on page 14, it is not necessary to calculate [1].
Since the 9219 is more flexible in the types of measures that it can bring, absolute accuracy for each use case is not provided. Instead, OR gives error of gain values and offset to be used for the calculation of the absolute accuracy [2].
Follow this logic to calculate the absolute accuracy:
(Absolute accuracy) = (entry reading) * (Gain error + drift in temperature) + (Offset + drift in temperature error)
Reading the line "RTD 4-wire or 3 wire Pt 100" in the table on page 24, the error of gain and offset for a module between 20 and 30 degrees Celsius is ±0, 1% of reading entry for gain and offset sectors ±2400ppm. Drift in temperature comes into play when the module is outside the normal operating temperature, but for Pt 100, gain drift is ±15ppm and the offset of the drift is the ±60ppm (see page 25).
So, for a module at room temperature 23 degrees Celsius and a Pt100 to 100 degrees Celsius using the 505 Ohm input range, the calculation is:
At 100 ° C, the RTD would measure 138.5 Ohms if its temperature coefficient 0,00385 Ohm/Ohm / ° C, then
Absolute accuracy = (138.5 ohms * 0,1%) + (2400 ppm * 505 Ohm)
= 1.212 Ohm + 0,1385 ohm
= 1.3505 ohmsfracture of 0,385 Ohm / ° C, and
Absolute accuracy = ±3, 5 degrees Celsius

A value of reading either excel or a text file
Hello
We are students working on a schoolproject where we want to control some output engines. We want to create a set of input values are in red in our program either excel or a text file.
For example, we want an entry to read the value '1' then the program runs its course and we get a result from the entry '1', after read the next value '2' and the program runs its course and so on.
We looked for clues and answers, but I suppose were really wrong with that. Someone here who could help us?
Less you can see one of our programs, its designed to control 3 fans depending on the input (ppm of CO). We want to replace the 'digital controller"(ppm of CO) in another 'thing' that gives us an entry in a list of values.
Well cordially

reading a file in app/native with fopen() and fgetc()
Understood that if I put a data file in my main folder (the same where PERMITS are stored and NOTICE) and when I then add this file as an asset in the bar - description.xml, I can open it.
At least in the debugger, FILE * fp = fopen ("app/native/file.dat", "r"); Returns what seems to be a file descriptor, it isn't 0 x 0 or - 1. However when I began to read the data using int c = fgetc (fp); I get data but not from my file. It seems to be completely random bytes.
Isn't funny that what was always supposed to be easier, is sometimes the most difficult wire trouble? I built a work-around, which worked fine on the emulator, but then failed to establish as the ARM of the machine code. He did that I am now too late for the PlayBook for free. :-(
Yes, I just saw this note on the deadline extended too! :-) It is now March 2, a lot of time for me...
Now, thank you very much to ask me to add the snippet of code, as in cut-and-paste, I suddenly noticed the mistake I had made. My active line in the bar - descriptor.xml looked like:
World.ppm which contains a typo, or better said a correction only partially executed. I changed 'png' to 'ppm' but I forgot to do it everywhere (2 x in the file xml, 1 x in the source code).
Happy coding again...

Anyone know how to solve my problem? I can't import my photos from Iphone to computer. Sign says: Photos in the camera cannot be imported because the IPhone is locked with a password or read. My phone is unlocked. I tried everything, every single idea. Without success! Any other idea?
For example, you specify that the device does not display the lock screen, correct? Do you use Touch IDS? If so, try to put your finger on the device to see if it's what he wants.
See you soon,.

Is there a way to read the settings in a .pst file?
Hi all!
I looked everywhere for info on this and found nothing. Anyone know how to read the settings contained in a .pst file? I found some that I really like, but would like to know what they are doing. In other words, what are the different used FX and what are their settings? I would use some other users have created as a starting point to create my own channels of FX. Open in a text editor doesn't show something like:
@^@^@D^@^A^A^@^@^@^@^KEMAGPPST^@^@^A^H^@^@^@^@Âp^@^@^@^@^@^@^@^@^@^@^@^@^@^@¿< 80 > ^ @^ @^ @^ @^ @^ @^ @^ @^ @^ @^ @^ @^ @^ @? < 80 > ^ @^ @@ ^ @^ @^ @
Is there a way to show somehow what they do and what they use the settings?
Thank you!
You're right, the settings file contain only of the code when opened in a text editor.
But why don't you just open settings in a project, this way of seeing exactly what Plugins are loaded. Opening of the plug-in window will show you their parameters.
The only restriction is that GarageBand has only a limited view of Plugin window which can not show all settings. To do this you must open in Logic Pro X.
Hope that helps

I am currently using OS X Yosemite 10.10.5. I bought in 2009 iMac with Snow Leopard and have to Lion then updated my current operating system. The internal dvd player has worked with much fussing, (insert the disc - closing - turn after a wait - by pushing the drive when he jumped on reboot). If I had the chance after a few hours, the video disc show up on my desk. When this happened, I was opening the dvd player that was in the Finder and the disc would play. I also tried to open the dvd first player and then insert the disc. That no longer works. Yesterday, only it just stop working. The reader still takes dvd and swirls and click as before but then ejects the dvd. Repeatedly stop and restart is no longer works. I make sure that the dvd be clean before I use it and have tried many different DVDs without success. I think it's a software issue. Does anyone have an idea/instructions a nearly dead grandmother brain that can follow to update or redate back to original factory setting to help this poor Smartdrive not so smart?
I have no TV, only my computer and phone at low prices. I need to watch that my library borrowed from the dvd.
Thank you.
Try a cleaning CD/DVD

How to clean a Superdrive DVD using a credit card!
I suspect the optical drive has failed. My 2009 Mac Mini could not shoot with same symptom 4 years ago.
To confirm a drive failure, insert a Snow Leopard installation DVD and try to start with the C key.
If this isn't the case, they drive could not be started.
I would just get an external optical drive, one powered with an AC adapter. The Superdrive Apple USB does not work without a hack.

"Read" notice on the application of instant messaging, a question?
IM Apple allows you to send a notice as a snapshot message was 'delivered '. I understand what it means. Recently, the opinion has changed to 'read '. I do not understand how the IM application knows whether or not the message has been read. I usually leave my IM window open when I use this app. It is therefore impossible to know whether or not I've read a message. I guess that more than others to do this. So that the 'read' notice means?
Messages has an option in the preferences/Messages/accounts, which allows the recipient to send read receipts.

Received message reading in 10 iOS Bug?
Hello
While I experienced it several times since the upgrade to iOS 10 (I had a 6s and now have an iPhone 7 more) I'm not find other reports of what I find curious.
I have a few friends who have read these receipts. I've seen for a long time (as I should) when they read my iMessage. However, I am certain that the following happened repeatedly since the iOS 10 update.
1. several iMessages will be displayed as "read" and time in a thread. The last will remain as "delivered", never change to 'read', but the recipient will respond to the message e-mail claims that they have not yet read. Obviously, it has been read, but does not display a confirmation of reading for all iMessages. That the final message never gets a read receipt, and then they return again as the conversation continues.
2. just the problem of this morning two took place once again so I know I'm not crazy. This morning I sent an iMessage. A moment later she clearly shows "read at 07:14. I went to my business, but it was strange for that person not to answer quickly. I looked back at the thread and now the same message showed as "delivered". The read receipt was missing.
The beneficiary was busy well, responded an hour later. When they sent their response confirmation of reading 'Read 07:14 ' returned. They had already read. Why the read receipt appeared, changed again to "deliveried" and then reappears only when they responded escapes me.
I'm positive these have two happen several times. I know major changes to Messaging. I can't imagine I'm the only user noticing it. Thoughts?
This certainly isn't a new issue with iOS 10. We have sporadic reports at least several months. There seems to be a relatively rare problem and I didn't follow it pretty close to remind that, if all solutions have been proposed. I recommend the forum search.

Adobe Reader can work with Safari 10.0?
These days, sites that require Adobe Reader to view content do not open in Safari. At least some of them, because who knows what technology is used to build each website that I visit?
What has changed here? Safari? Adobe?
I still do not see Adobe Reader as an extension that can be installed for Safari.

Try to install Adobe Reader. Usually, that installs a plugin Safari. You will need to go to preferences to set up.
