GENERALDESCRIPTION.

TheMeggerDET62DDigital Earth Tester is a compact portable instrument designed to

measure earth electrode resistance quickly and accurately. Powered by six LR6battery

cells, the instrument is very robust and has a tough case moulded in ABS plastic.

The instrument uses the three-terminal method of measurement in which the '

X' terminal

is connected to the earth electrode under test, and the 'C' and 'P' terminals are connected

to Current and Potential test spikes. Test frequency is 128 Hz to avoid problems from electrical

mains ‘Noise’.

Test leads and auxiliary electrode test spikes can be supplied as part of an earth testing

field accessory kit which is available as an option.
