This self-powered and watertight tester was designed for measuring earth connection
resistances in outdoor sites.  It is particulary adapted to harsh environments and may be used
in all weather conditions.

It is very easy to use thanks to:
■ a single pushbutton for triggering your measurements
■ a large galvanometer, directly graduated in Ω
■ three lights indicating any fault liable to vitiate test results
■ a low-battery indicator built in the galvanometer
■ three color-coded screw-on terminals making test connections easier
■ one captive bar
