# «Percentages in labview»

Beginner,

How you would show a percentage of thin values by using an indicator in labview 8.2

Advertisement

Assuming that you know how to calculate these percentages, an indicator displays just the value. If you want the percentage under the number sign, use advanced formatting and make for example ' %f % ", the percentage of double will force the display of a single percent character.

• Image Matching with Labview or model

Hi all!

I am currently implementing a picture matching algorithm on two .png images (let's call them model and Photo).

The idea is that the template contains an examply of which must be shown in a certain part of the picture.

Model and photography have sizes of different images.

What we want to achieve is:

1 find the return on investment in the Photo where the model is likely to be found

2. compare the KING with the real model

3. get a percentage of similarity (e.g. 90% similar-> specific Match, 70 to 89 %-> accordingly Match Possible, <70%similar -="">not a match)

Do you have ideas on how we might put implement this?

We currently use LABView 2015 SP1 - 32 bit with the add-on of the Vision

We had to use a modified version of the model Inspection.vi Golden (can be found) but are blocked because the IMAQ compare continues Golden Template Module return the error message attached to this post.

Any comment on the possible debug is also welcome!

Thank you!

A model is *.png with info vision (for example, settings, info, etc.). You must create the model using model editor which should be installed and accessible from the start menu.

• by using labview co-simulation, how to control the PWM market factor in multisim

I am new to the use of Multisim with LabVIEW using co-simulation. I would like to ask if there is a PWM component in Multisim, which can have its cycle have to be controlled using LabVIEW? I have an algorithm in LabVIEW that returns the duty cycle values between 0 and 1, representing the percentage of duty cycle.

How can I control the PWM market factor in Multisim using LabVIEW co-simulation?

• How to make the difference in percentage between two matrices?

Hello everyone, I just want to ask how to make the difference in percentage between two binary matrices. This is to compare two images converted to matrices in LabView. Thank you.

Well, in the current image interesting pixels are zero in the reference image. Here is a small example that would take all the zero 100% pixel, then look at the pixels of same in the other image to see how are always 0.

Modify if needed.

• percentage of absolute units PID

Hello!

I want to update and make some changes on an old LabView project, done like 10 years ago.

I opened it in my 2012 LabVIEW. A VI make sure PID control, and it contains a VI the obsolete PID toolkit. I have attached the VI simplified with some notes made by me, I left only the relevant parts of the VI as a whole.

What I want to do is to implement the same control but in LabView 2012, using advanced PID VI. I would also use the absolute values for the PID, so don't not percentage values.

I got a little confused with this very old VI, I hope someone can clarify the situation for me.

My questions:

1, in my new LabView VI, I will automatically be set the range on the Keithley, when it is necessary during the control. Given that I'll use absolute value for the PID, which gain approach P should be used?

(I guess the I and D can remain the same) Should I use P = 0.03? Note, I want to the wire that the value of process directly to the advanced PID VI, not the difference between the PV and SV. Also, the PID on must be directly in Ampere, connected directly to Keithley screws.

2, in this old VI, what "iteration" means? I don't see any similar parameters between my toolkit LabView 2012 PID live...

3, I wonder, too, why the developer in the old days used dt = 20 s, and structure has been placed in a while loop traveled in 1 second. What that entails actually in control
I am interested because I would like to make a very close copy of this VI, but somehow new, as explained above.

Thanks much for any note, advice and help.

Best regards

You may think the P gain as a ratio of output devices to deal with variable units, which could help you to calculate the correct gain setting when you change units (in percentage of absolute units). However, I missed where the percentages here - are all PV is no logic not any sense. Why it calculate the difference between the setpoint and process variable, multiply it by a large number, then tighten it between-100 and + 100 and use it as the process variable? It's unlikely work well, because the variable setpoint and process should have the same units, they not here. You may be better off than fixing and then retune the controller.

Senior year "iteration" is somewhat similar to the entrance of "Reset". You can search in the VI and see what he does. For most it resets the Integrator and disables the derived control when it is 0 (the first iteration). It also disables the process variable of filtering for the first 3 iterations. The idea is that you connect directly to the terminal of the iterator of a while loop.

I don't see where the dt is set to 20. The dt is purely a mathematical structure, and assuming that the timing is consistent from one iteration to the next, you can set the I and the D values to match any dt value and get the same result. A detachment of the 1920s and a me 20s should be identical to a detachment of 1 s and an I 1 s (note, however, that in the current PID toolkit, I made a few minutes even if dt is in seconds) - in both cases, you are saying that the full time is a simple loop cycle. Definition of dt to do anything other than-1 is mainly useful to simulate a controller offline, for example in the simulation, if you can run the controller much faster than real-time.

• Conversion of coordinates to screen coordinates of part of LabVIEW

Hi all.

I have a reminder of .NET that returns percentages of screen which I want to convert them into LabVIEW Panel coordinates.  The goal is to have an indicator move to the right in the LV Panel coordinates when the .NET event fires.  The management of the events is supported, but I have a problem with the math converting the percentage of the screen in an accurate position on a glass of LV.

The first thing I did is to multiply the percentage by the resolution of the screen, but I'm stuck on how to take the screen pixel data and understand where it is compared to the part of the LV.

I'm sorry if this was not the message more clear, I'll try and clarify any questions if I can.  Thank you very much for your support.

• Summary report - percentage of successful tests

Hi all

I develop a sequence with many steps of pass/fail tests, and I would like to change/simplify the report so that the user could see the percentage

tests succeed on tests executed together, after the end of the sequence.

In addition, I would like the report to be displayed in the Excel file.

I don't have a lot of experience in TS and I don't know where to start.

Any ideas?

Thank you very much

Levi S

I enclose a simple sequence that displays pass fail statistics in the report.

I use additional results for report pass and fail. You can change as a result of performance if necessary.

Please note that the steps to calculate the col and not having results tombstone.

All results are loaded in the list of locals.result and analysis of the sequence of this variable to determine the pass-fail.

Some useful links for the customization of the report (excel)

• How to change the picture proportions in LabVIEW?

I would change the aspec ratio of my image. Is this possible in labview.

Can show the example. I would like to take this picture:

• percentage of data

Hello

I have a table 2D (dimensions 62 x 24 models lines) and cary values in the range 0... 20. in addition, there are 3 limits (L1 = 1.22, L2 = 2, L3 = 10). What I have to do is to see how many values in each column, are below L1, how between L1 and L2, L3 and L2 and how many of them are bigger than L3. These figures, I need to be saved in 4 tables 2D.

For example if the original 2D array is:

1 3 7

0 5 11

3-6-2

tables 1 d of output are:

A1 (for values less than L1)

2 0 0

A2 (for values between L1 and L2)

0 0 1

A3 (for values between L2 and L3)

1-3-1

A4 (for values greater than L3)

0 0 1

Please help, I'm new to Labview...

 The title is the percentage of occurrence Data... I need tables 1 d as indicated above, because after that, it is very easy to turn that into percentages (by dividing by the total number of lines)

Sounds like a job for the General histogram VI.

Set the locations (e.g.,-Inf, 1.22; 1.22,2; 2.10; 10, Inf) and enter your data in the VI (a single column at a time).

• iPhone battery percentage 6 stuck

Hello, I have an iphone 6 purchased from Apple about the release two years ago, never had any problems until this Friday, 10 March 16 when I noticed my battery percentage was is no longer draining after moderate use. He would stay at 100 percent every day and then turns off randomly. I have iOS 10.0.2, have tried to reset, power on/off, restore factory... nothing works! Is someone able to please shed some light on why this might be the case? Google tells me that there was a similar problem earlier this year when those who have no zone defined as auto has encountered a similar problem with the battery percentage being stuck and not up-to-date (i.e. no reflective battery drains with use). I went to settings and noticed that my time zone was not set as automatic. Does anyone else have this same problem and what is the reference for this?

I'm surprised that factory reset did not fix this problem... help...

Hello.

First, plug in your iPhone, let the screen off and do nothing for a long period of time. Leave it plugged in all night while you sleep is perfect for that.

Then, restart your iPhone by pressing and maintaining the sleep/wake and home buttons.

You can also try following the suggestions of battery life. Go to settings > farm > find 'Suggestions of battery life.

In addition, it is preferable to follow the Apple recommendations given in this article http://www.apple.com/batteries/maximizing-performance/

• iPhone battery percentage 6 unreliable

Hi all! I use an iPhone 6 with the updated iOS (10.0.1 for now). Since iOS 9.3.4, I noticed a lack of reliability of the battery of my iPhone.

During normal use, the percentage jumps down about 10-15%. If at this time that I plug the battery pops up by about the same percentage. In other cases, the iPhone still for a long period of time even with the battery that may not be true, or it shuts down even if it is not 1%.

I went to the Genius Bar and the genie made a diagnosis called 'mobile Inspector' who has not revealed something strange. The employee told me to calibrate my battery, follow these steps:

(1) restore settings (no);

(2) use the iPhone until it stops;

(3) leave here 2 hours without connection;

4) recharge 100% free to use it and leave it there for 2 hours more.

(5) repeat step 2-4 once.

I did what she suggests, adding a force restart after point 4.

The problem is still there. Day before yesterday, the percentage rose from 85% to 90% (without connection) and yesterday he jumped from 40% to 30% and then stayed at 3% for 1 hour.

I booked a call of support for tonight see what I can do. The iPhone is still covered by the warranty of 2 years Italian.

I encountered this problem a few months ago. I went to a Genius bar and my iPhone has been replaced. I don't know if genius made the same tool of diagnosis or a closer, but he acknowledged that the problem was due to hardware, perhaps due to the battery connector. They do not have to replace the battery, but gave me a refurbished iPhone.

Someone at - he seen this problem and found a solution?

Thank you

Hello, first try the following general steps. They could help.

1 reset your iPhone by pressing and holding the sleep/wake and home buttons.

2 disconnect you from your iCloud account and reconnect again.

• 6 iOS10 incorrect percentage battery iPhone

On my 6 running latest iOS iPhone 10 (10.0.1) my battery indicator in percentage is incorrect most of the time. I can't tell if the percentage indicator is stuck or something. This happened 9 w/IOS, but seems aggravated with iOS 10. Here are two typical scenarios:

1. indicator indicates the value > 50%, but then stops

2. indicator indicates the value ~ 10%, but then when it is plugged in charge indicator of cable past at 30%.

I see that when people are complaining about this preliminary response was to "upgrade to iOS 9.3 +'-well, which obviously does not work for me." I would like to have an indicator that represents the amount of battery life I have left.

• Find the percentage of double pairs false in five two sets of columns

The situation is that I have four sets of two related columns, and these four sets are repeated during 17 sheets. They are all checkboxes (essentially and or or), and I've already configured to do a little when one of them is checked.

What I want to understand, is if it is possible to indicate the percentage of a pair of two time column to be false. I want to compare, over time (represented by worksheets), how each pair of column.

Here is a screenshot. Currently, I am tagging manually false lines double red, but I would like to than my 18 leaf, which collects information about the rest, to quickly view how each column pair done.

You can count double false according to the following formula:

= COUNTIFS (A, B, FALSE, FALSE)
