The Megger 230315 / 230415 / 230425 AC and AC/DC High-Pot Testers are designed for safety and ease of operation, and readily adapt
to development, maintenance or production testing. Three models are available: two ac and one ac/dc. The AC High-Pot
Testers feature a front-panel, NEMA 5-15R three-prong output receptacle. Booted, alligator-clip output and return
probes are also supplied with all models.
Test voltage is continuously adjustable from zero to full output, with a zero-start interlock. Leakage current trip
level may be adjusted from 0.3 to 12 mA by a front-panel knob. Pushbuttons are provided to select one-second or
continuous testing, to turn off the high voltage and to reset the instrument. All high-voltage connections are recessed
to prevent accidental contact with high voltage.
During testing, high voltage will automatically shut down within 50 ms of arcing or exceeding the preset trip level.
Visual and audible alarms alert the operator upon failure.
The instruments also feature an interlock that prevents the high voltage from being applied if the supply ground wire
is open or if the hot and neutral wires are interchanged. ATester Grounded lamp lights to confirm the instrument is
connected to a properly grounded power source.
The AC High-Pot Testers will automatically shut down if ground circuit resistance of the test object exceeds 15
ohms at any time during testing. This feature may bebypassed when testing double-insulated devices or when
using test probes. The AC/DC High-Pot Tester provides a slide switch to select either ac or dc test voltage. The slide
switch safely covers the output jacks not in use.
