DC Voltage Measure Verification
To do the dc voltage measure verification test:
1. Push

repeatedly until VOLTS is shown on the third row of the Product
display.
2. Connect the Product red banana jack (V mA) to the Calibrator HI VOLTS
output.
3. Connect the Product black banana jack (COM) to the Calibrator LO VOLTS
output.
4. Set the Calibrator for the voltage setting in Table 4, and verify the display
reading on the Product.
