I encounter several
problems with a K2000 Multimeter, during the acquisition of tensions on 4
different channels with Labview 7. The program uses the VI of the library of the
driver of K2000 for Labview 7.The stages are as follows:
2- Configure DC Volts: PLC = 10
3- Configure Trigger: Source = Bus, Initiate = Continuous, Custom count =
4- While loop containing a For loop of 4 iterations selecting the number of the
channel by mean of a condition structure which contains: a- Configure Route
Single: Close, n° channel b- Action send
trigger c- Wait for
1000ms d- Data Read Single
The list of the 4 channels is not an increasing list of consecutive
1- the execution stops after 5/6 measurements at Wait for RQS in spite of the
time out of 25000ms.If I remove Wait for SRQ in Data Read Single I do not have
this problem any more.
2- the error -211(trigger ignored) appears at the beginning of the execution.
If I choose don't reset in Initialize this error does not appear any
3- if I apply a filter with Moving Average and 10 Readings, I obtain incoherent measurements
and this, whatever are the values of the time delays introduced in Trigger and
before Data Read Single.
I read all documentation on the site of Keithley but I did not find a solution.
So I need some indications especially for the third problem because I must
imperatively filter measurements.
I thank you for the assistance which you could bring to me
