B: Calibration Series 2600B System SourceMeter® Instrument
B-22 2600BS-901-01 Rev. B / May 2013
Step sequence
Adjustment steps must be performed in a specific sequence. See the following table that is specific
table to your model. Note that all steps are performed using 2-wire (local sensing) except as noted.
Adjustment of each range is performed as a four-point calibration:
• + ZERO
• + FULL SCALE
• − ZERO
• − FULL SCALE
Before performing the adjustment steps, refer to Parameter values (on page B-21) and Sense modes
(on page B-21).

1. Calibrate only the source for the CALA sense steps.
2. Steps must be performed in the order shown.
3. 10 A range for changing calibration of range only and is not available for normal use.
4. Do not use actual 0 values for zero calibration points. Send very small values such as ±1e-30. Calibration polarities must also be
set as shown in the procedures.
5. Output must be off before changing to the CALA sense mode.
