To prevent possible electrical shock, fire, or personal injury,
ensure that the calibrator is in standby mode before making any
connection between the calibrator and the Test Tool.
Dangerous voltages are present on the calibration source and
connection cables during these steps.
The adjustment steps for channel C and D are only for the models
190-104 and 190-204.
To do the Input ABCD (AB) Volt Gain calibration:
1. Press
2. Connect the Test Tool to the 5502A as shown in Figure 5-16.
