Figure 7. Source Voltage Accuracy Test, "R" Nominal
Source Voltage Accuracy Test, Open Circuit
The open circuit source voltage accuracy can be determined, by calculation, using the
Meter Voltage Reading Error % previously noted. Complete the following test to verify
the actual open circuit source voltage.
1. Set the UUT rotary function switch to an insulation test function.
2. Press T and record the UUT display reading for each step in
Table 6.
