Series 2600B System SourceMeter® Instrument Reference Manual Appendix B: Calibration
Parameter values
The full-scale parameters are actually 90% of full-scale as indicated (see the table contained in Step
sequence (on page B-22)). Note that you cannot send a value of exactly 0 for the two zero
parameters. Instead, you must send a very small value, such as 1e-30 or -1e-30.
Sense modes
The preceding table for your specific model lists the sense modes for the calibration steps. Note that
each source and measure range is calibrated using the LOCAL sense mode. In addition, for the
Model 2601B/2602B/2604B, the 100 mV source and measure range is also calibrated using the
REMOTE sense mode, and the 1 V and 1 mA source ranges are also calibrated using the CALA
sense mode; for the Model 2611B/2612B/2614B/2634B/2635B/2636B, the 200 mV source and
measure range is also calibrated using the REMOTE sense mode, and the 2 V and 1 mA source
ranges are also calibrated using the CALA sense mode.
