Ground Wire (Protective Earth) Resistance Test
The Ground Wire (Protective Earth) Resistance test
measures the impedance between the PE terminal of the
test receptacle and the exposed conductive parts of the
DUT that are connected to the Protective Earth of the
DUT.
Note
Before you do leakage tests with the Product, it
is best to make sure the ground connection is
good.
Do this test between the test receptacle ground and the
Protective earth ground of the DUT or DUT enclosure.
To access the Ground Wire (Protective Earth)
∅ /Null
Resistance Test menu push .
Note
The DUT is turned off for this test.
To do a ground wire resistance test:
1. Make sure the power cord from the DUT is
connected into the test receptacle.
2. Push  to reveal the resistance function menu.
3. Connect one end of a test lead to the V/ Ω /A jack.
4. If you use an accessories probe, connect it to the
other end of the test lead and put the probe tip into
the
∅ /Null jack. If you use an alligator clip accessory,
connect it to the other end of the test lead, put the
null post adapter in the
∅ /Null jack, and clamp the
alligator clip to the null post adapter.
Note
The ∅ /Null jack does not accept the test leads
supplied with the Product.
5. Push the Zero Leads softkey. The Product zeroes
out the measurement to cancel the test lead
resistance.
6. Connect the test lead from the V/ Ω /A jack to the DUT
enclosure or protective earth connection.
