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
•

Before performing the adjustment steps, refer to
(on page B-13).

1
Calibrate only the source for the 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-30. Calibration polarities must also be
set as shown in the procedures.
4
Output must be off before changing to the CALA sense mode.
