Insulation Function, External Sense; Source Voltage Accuracy Test, "R" Nominal - Fluke 150X Series Calibration Manual

150X Series
Calibration Manual

Insulation Function, External Sense

This test verifies that the Tester will sense a voltage >30 V when present on the circuit under
test.
1. Connect the DUT
terminals.
2. Set the 5320A to the voltage output function (V).
3. Turn the DUT rotary function switch to an insulation function.
4. Apply 35 V, 50 Hz to the DUT.
5. Verify that the DUT displays >30 V in the primary display, and the red LED lightning bolt
comes on.

Source Voltage Accuracy Test, "R" Nominal

Complete the test steps in
load. If you use the Fluke 5320A, use the high resistance function to verify source voltage.
1. Connect the Fluke 5320A high resistance output terminals to the DUT
terminals.
COM
2. Put the Fluke 5320A in the high resistance function (H).
3. Set the Fluke 5320A for the applied load shown in
4. Press T and verify that the DUT and Fluke 5320A voltage reads within the limits of
Table 6. Record both readings.
5. Use the Fluke 5320A voltage reading as the reference and calculate the DUT voltage
reading error %, (5320A V - DUT V / 5320A V) x 100, and record for later use.
