This is a very handy, easily portable and simple to use

earth tester. A large liquid crystal display shows

earth/ground resistance and continuity.

The E1610 uses the four terminal measurement method

in which the resistance of the current circuit test leads

does not affect the reading. The resistance of the

potential circuit test leads can also be ignored because

the measuring circuit has an input buffer stage to

prevent loading of the earth resistance under test.

The carrying case, supplied, has been designed to

allow the tester to be operated in the case.

Vital for very low resistance testing.

Requires earth spike kit (see below).
