Input A, B, C, D DC Voltage Accuracy Test

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 test steps for channel C and D are only for the models
190-104, 190-204, and 190-504.
