2.5.2.1 Offset Calibrations
1. Ground the channel(s) you want to calibrate directly at the channel header(s), J17 and J22 for the voltage
channel, J24 and J26 for current channel. The channel(s) could also be grounded directly at the screw-type
terminals.
2. Press the corresponding AC or DC offset calibrate button (Cal V, Cal I, or Cal Both) beside or below the
offset register fields.
3. The calibration value(s) will automatically update when the calibration is completed.
2.5.2.2 Gain Calibrations
1. Attach an AC or DC calibration signal to the screw-type terminals, and make sure the corresponding chan-
nel headers (J17, J22, J24, and J26) are set to the input position.
2. Press the corresponding AC or DC gain calibrate button (Cal V, Cal I, or Cal Both) beside or below the gain
register fields.
3. The calibration value(s) will automatically update when the calibration is completed.
The Calibration window also contains the Power Offset Register display and adjustment. The user can
read and write the values in the Power Offset register (Poff).
