Digital Ground Tester
DESCRIPTION
The new ground testing instrument family from Megger
offers a unique solution to your ground stake testing needs.
The complete kit of instrument, test leads, stakes, batteries
and calibration certificate are delivered in a tough poly-
propylene carry case - everything you need to start testing in
one kit.
The ground rod tester is rated to IP54 meaking it truly an
outdoor instrument. The ground tester has been designed
to be easy to use - a large selectror switch makes selection of
2 pole or 3 pole test easy with gloved hands - and the design
makes the fitting of shorting links to perform 2 pole tests
a thing of the past. Using the optional clamp around the
ground rod connection allows the testing of the rod without
the need for disconnection, leaving the earthing system
intact during testing (ART). A large, clear, easy to read LCD
display and thumb sized test button again makes the
instrument particularly suited to the outdoor conditions of
ground testing.
In addition to this ease of use, the ground tester also auto-
matically checks the connection of the P spike and C spike,
indicating the status on the display. The instrument also
includes a voltmeter to allow you to measure the ground
voltage. The ground tester can measure resistance from
0.01 Ω through to 2000 Ω and earth voltages up to 100 V. To
allow accurate testing in noisy environments the instrument
is capable of rejecting noise of up to 40 V peak to peak.
The Megger digital ground tester is powered by eight AA
batteries which are widely available and also give excellent
testing time - the status of these batteries is given bya bar
graph on the LCD display allowing you to decide when to
change the batteries, before they expire.
The Megger ground testers are designed to meet stringnet
safety standards and are rated CAT IV 100 V.
