Issues with the Fluke 725 Calibration Procedure
Has anybody been having problems with the Fluke 725, FM ver. 2.20, failing the current source tests? I have stepped through the program line by line and I have found the program feeds the com port 1 bit at a time. This is fine if your testing at 9ma and below but go any higher than that and it fails. Example: the source test is 24mA. The global variable is @command is set to a24 (a is setting the lower screen to source mA). The sub routine loads the first value (a) and then increments the local register (L) by one and then reads and loads the next value (2). The UUT is then set to output 2mA. Then L is incremented again to grab the last value of 4. On the load, the UUT inputs 4mA. Bingo - an automatic failure. The UUT is not set to 24mA but to 4mA. I have tried everything in my tiny knowledge to fix this but to no avail. Thoughts?????
