Error code 5005 Keithley 2602A not detected

[Ben_Arts]

Hi,

I use the Keithley source/meter 2602A in labVIEW2011.

An error code 5005 occurs (value to big) on the front display.

This error is not detected by the driver.

In the driver the global ErrorQuery keeps False even if an error occurs.

If i set the case to true manually then the error is readed back form the instrument.

I've attached the Driver where the problem occurs.

Why isn't it detected by the driver?

Kind Regards,

Bernard Arts

Hi Bernard, 

Please see the following thread for information and examples of interfacing with the Keithley 2602A.

If this doesn't help, please could you explain the issue a bit further. When exactly does this error occur? Where does it occur (what front panel)? 

You state that you expect the error to be in the global variable, where would this be written? 

Kind regards, 
Matt

Hi,

I'found the problem. At Initialize the error query global must be set true otherwise no errors are detected (read from instrument).

The error happens on the screen of the instrument (so i can see that an error occurs) but it was not detected by the sub vi because at initialize the error query was set false (default).
