Volt and Insulation Functions
To verify the accuracy of the UUT volt and insulation functions:
1. Turn the UUT rotary switch to VOLTS V position.
2. Press < until L-PE appears in the upper left corner of the display.
3. Connect the L and PE input jacks of the UUT to the 5320A V, HIΩ, mA~ Output
terminals as shown in Figure 5.
4. Apply the Input Level for steps 1 through 3 of Table 3.
5. Compare the UUT display reading with the Display Reading Limits in Table 3.
6. Set the 5320A to .
7. Set the UUT rotary switch to INSULATION R
ISO.
8. Press  on the UUT to set to the requested range.
9. Repeat steps 4 and 5 for each step of the Insulation function.
10. Use the UUT  to start each measurement.
