Equipment to
be measured
・ If measurements are taken between exposed metal components (components
that are electrically connected to ground) and hot power lines, the resulting
condition is the same as a short to ground and the leakage breaker trips. For
class I equipments, disconnect the protective earth conductor before
measuring.
・ Use the insulating transformer when the standard requires it. Do not alter
the contact conditions with the test lead left connected to the leakage current
measurement terminal. In some cases, this may be the same as the earth.
(2) When setting to "between the enclosure and the earth."
1. On the enclosure leakage current measurement screen, set the contact
condition to "between the enclosure and the earth."
2. Plug the power cord of the equipment to be measured into the auxiliary
power socket found on the right side of the 3155.
No connection is made for
internally powered equipment.
3. Connect the red 9170 TEST LEAD to the leakage current measurement
terminal T2.
4. Touch the red 9170 TEST LEAD to the enclosure of the equipment to be
measured.
If the enclosure or any part thereof is made of material with insulating
characteristics
If the enclosure or any part thereof is made of material with insulating
characteristics, attach the 9195 ENCLOSURE PROBE to the enclosure across
the entire surface.
