Model 2635A/2636A calibration steps
Parameter values
The full-scale parameters are actually 90% of full-scale as indicated in
, and
. Note that you cannot send a value of exactly 0 for the two zero parameters, but must
instead send a very small value, for example 1e-10 or -1e-10.
Sense modes
list sense modes for the calibration steps. Note that all
source and measure ranges are calibrated using the LOCAL sense mode. In addition, the 100mV
or 200mV source and measure ranges are also calibrated using the REMOTE sense mode, and
the 1mA and 1V or 2V source ranges are also calibrated using the CALA sense mode.

1. Calibrate only the source for the SENSE_CALA sense steps.
2. Steps must be performed in the order shown.
3. Do not use actual 0 values for zero calibration points. Send very small values such as ±1e-10.
Calibration polarities must also be set as shown in the procedures.
4. Output must be off before changing to the CALA sense mode.
5. For Current Measure only.
