Tool and Appliance Tester
DESCRIPTION
The Tool and Appliance Tester combines, in one portable
instrument, the three most frequently specified electrical
safety tests for tools and appliances. In conformance to UL
and ANSI test requirements, the instrument performs test
of ground continuity, leakage current, and electrical
insulation. It also checks the nameplate current rating of
the device.
APPLICATIONS
Poorly maintained electrical tools can become a safety
hazard and cause injury to personnel. Testing electrical
tools on a regular basis is not only safe practice against
costly repairs, but may even reduce liability. Applications
for this handy instrument include in-plant OSHA safety
surveys and production line, tool r
safety checks.

Leakage Test
This test measures the current that would result from the
ground conductor being accidentally severed; that is the
current to which the operator would be subjected if
providing a path to ground at normal line voltage. A
switch is provided to select testing at normal or reverse
polarity. Measurements from 0 to 10 mA are indicated on a
large, 3.5-in. (89 mm) analog meter with sensitivity greater
than 0.01 mA. To ensure the accuracy of the meter, a
calibration check can be initiated at the push of a button.
