Case Leakage Current Measurements:
Move the Mode switch to CASE LEAKAGE. See Figure 2.
The Earth Leakage (or Ground Leakage) Current is measured through the ground
conductor of the Device Under Test. This is only applicable to devices with a three-
conductor power cord.
The leakage measurement is made internally when the Ground switch is momentarily
opened. The LCD will display the measurement in Micro Amps. There is no other
connection required.
To measure the Case Leakage of devices with plastic enclosures, wrap aluminum foil
around the case and connect the test lead to the foil.
The Case Leakage Current is measured through the test lead cable. Connect the test
Lead to the case of the DUT (Device under test). The leakage measurement is made
when the Ground switch is momentarily opened. The LCD will display the
measurement in Micro Amps.
Both Earth and Case Leakage Current measurements should be made in all power
switch combinations with the Polarity switch in Normal and Reverse, and the Neutral
switch Open and with the DUT On and Off.
CAUTION
When switching from Normal to Reverse or vice versa, make sure to pause the
rocker switch in the off (middle position). Power to the outlet will be OFF in the
open neutral position.
Device Current Measurements:
Move the Mode switch to DEVICE CURRENT. Set the polarity switch to normal. Turn
the DUT On. The LCD will display the Device Current in Amps.
CAUTION
Do not attempt to open the unit. There are no user serviceable parts inside.
Further, the warranty will be void if the unit is opened by other than Netech
trained personnel.
