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, and J24 and J26 for the current channel. The channel(s) could also be grounded
directly at the screw terminals.
2. Press the corresponding AC or DC offset calibrate button(s) (Cal V, Cal I, or Cal Both) in the Offset
panel.
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 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(s) (Cal V, Cal I, or Cal Both) in the Gain
Panel.
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 fields. The user can read
