Calibration adjustment overview

The following topics contain an overview of the entire calibration adjustment procedure.
Parameter values
The full-scale parameters are 90 percent of full-scale as indicated (see the table in
page A-19)). Note that you cannot send a value of 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.
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
(on page A-19).
