Insulation Function, External Sense

The following test verifies that the Tester will sense a voltage > 30 V when present on the
circuit under test.

Source Voltage Accuracy Test, "R" Nominal

Complete the test steps in Table 6 to verify source voltage of the insulation function
under load. If using the Fluke 5320A, use the high resistance function to verify source
voltage.

voltage output terminals.
2. Set the 5320A to the voltage output function (V).
3. Turn the UUT rotary function switch to an insulation function.
4. Apply 35 V, 50 Hz to the UUT.
5. Verify that the UUT displays > 30 V in the primary display, and the red LED
lightning bolt comes on.
1. Connect the Fluke 5320A high resistance output terminals to the UUT
and

2. Put the Fluke 5320A in the high resistance function (H).
3. Set the Fluke 5320A for the applied load shown in Table 6 for Steps 1-5.
4. Press T and verify that the UUT and Fluke 5320A voltage readings are
within the limits of Table 6. Record both of these readings.
5. Using the Fluke 5320A voltage reading as the reference, calculate the UUT
voltage reading error %, (5320A V - UUT V / 5320A V) x 100, and record for
later use.
