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 making it truly an outdoor instrument. The ground tester has been designed
to be easy to use - a large selector 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 instru-
ment 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 by a 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 stringent
safety standards and are rated CAT IV 100 V.
