Hi,
we have been using the ke24xx.dll library for developing a own .vi program which controlled the operation and the measurements of a resistor. However, two days ago the program started to measure badly, that is, the measurement of the front panel window of the instrument didn´t correspond to the sent value to the PC.
We are using a NI-GPIB-USB-HS and we have installed the NI-488.2 driver (the same which has been used until the occurrence of the discrepancy) and we have been testing the device with other programs based on the same library, another NI-GPIB-HS, and another laptop. All the tests were wrong.
On the other hand , we have tested the same configuration using the Labtracer 2.0 supplied by Keithley (it is developed with Labview so I understand it is using the same driver) and this test has provided good results, the measurement of the front panel of the device coincide to the measurement of the sent data.
We do not understand what is happening. Has someone ever had the same problem? It is possible that the library could be corrupted?
We have been used different computers, different GPIB-USB devices and the problem is the same
Is there anything we can test? Could it be related to the driver (mismatch between 488.1(keithley) and NI-488.2?
Thanks in advance
Juancar
