....................................................................................................................................................................
Autonomous and watertight, this tester is a worksite instrument designed for earth resistance
measurements. It is particularly suited to measurements in difficult conditions such as when
there are stray voltages present, high telluric currents, high value auxiliary electrode
resistances, etc...
For ease of use, this instrument has the following features:
I a single press button to trigger the measurement
I an autoranging system for measurement range switching
I a large digital display which is readable even in shadow
I three indicators that signal the presence of faults which can lead to errors during measurement
I three colour coded screw terminals to simplify connection of leads
I an attached connection rod
