LKG 610
Netech Corporation
110 Toledo St, Farmingdale, NY 11735,
Operating Instructions
1. Line Voltage Measurement:
The default measurement setting is line voltage (LINE VOLT). When the LKG 610 is
plugged into an AC outlet, the LCD will display the measured line voltage in Volts. If the
outlet polarity is reversed the display will indicate ‘- POL’ and line voltage will not be
displayed.
2. Device Current Measurement:
Plug the Device Under Test (DUT) into the test receptacle. Set the polarity switch to
normal. Press the “DEVICE CUR” key. Turn the Device Under Test (DUT) On. The
display will present the Device Current in Amps.
3. Earth Leakage Current Measurement:
Press the “EARTH LKG” key. See Figure 2. The Earth Leakage (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 CHS GND switch is momentarily pushed to
the LIFT GRND position. The display will present the measurement in
µ
Amps. No other
connection is required.
Both Earth and Case Leakage Current measurements should be made in all power
switch combinations: the Polarity Switch in Normal, Reverse, and off; and with the
Neutral Switch Open and Closed.
Caution
When switching from Normal to Reverse or vice versa, make sure to pause the
rocker switch in the OFF position (middle). Power to the outlet will be OFF in the
open neutral position.
