Users Manual

Prior to conducting any leakage tests with the Analyzer, it is best to test the integrity of the ground connection between the Analyzer’s test receptacle ground and the DUT’s Protective earth ground or enclosure with this test.

To access the Ground Wire (Protective Earth) ∅/Null Resistance Test menu press O.

Note

The DUT is powered off for this test.

To perform a ground wire resistance test:

1.Ensure the power cord from the DUT is plugged into the Analyzer’s test receptacle.

2.Press Oto reveal the resistance function menu.

3.Connect one end of a test lead to the V/Ω/A jack as shown in Figure 9.

4.If using an accessories probe, connect it to the other end of the test lead and place the probe tip into the ∅/Null jack. If using an alligator clip accessory, connect it to the other end of the test lead, place the null post adapter in the ∅/Null jack, and clamp the alligator clip to the null post adapter.

5.Connect the other end of the test lead to ∅/Null jack.

6.Press the softkey labeled Zero Leads. The Analyzer zeroes out the measurement to cancel the test lead resistance.

7.Connect the test lead coming from the ∅/Null jack to

the DUT enclosure or protective earth connection.

8.The measured resistance is displayed as shown in Figure 8 after the DUT connection(s) is/are made.

WX Warning

To avoid electric shock, remove the null post adapter from the ∅/Null jack after a test lead zero is performed. The ∅/Null jack becomes potentially hazardous during some of the test conditions.

A low resistance reading is required to confirm a good ground connection through the power cord. Refer to the appropriate electrical safety standard for the specific limit value to be followed.
