Ok, I've been able to calibrate voltage in both channels without problem, and now it is looking much better. But with current I have a problem. When I clear the calibration parameters for CH1, at 0.100mA I get no current at all through the electronic load, the multimeter is even measuring -0.0013mA. I'm able to adjust the 'b' parameter without problem and in fact at 2.5A everything matches to the mA, but when I start to go down in current, it starts to diverge, at 200mA I read 70mA and at 100mA I read 0. Any clue what should I do? I've tried several times, calibration only display current, only setting current and both values at the same time, with no change. I always start the calibration by clearing the values with
*CLCLS 2
*CLCLS 3
then set the display current values with the corresponding
CALibration:CURRent ch1,1,0.000 (I've also tried with -0.0013)
CALibration:CURRent ch1,2,2.3687 (or whatever I measure, usually after clearing the values I always get to 2.3687A)
and the same for setting current
CALibration:CURRent ch1,3,0.000
CALibration:CURRent ch1,4,2.3687
Any clue? Voltage calibration was so easy and effective, but I'm lost with this 0A at 0.100mA setting. I've also tried with a very small value, 0.0001 or something like that, just in case 0 is not a nice number for the firmware.
Thanks!
