How To Use Wrist Strap and Earth Tester

When testing, the operator simply connects their wrist strap to the tester via the 4mm banana plug socket or 10mm stud.

To test, make finger contact with the stainless washer and push the button then “press to test”. A green LED will illuminate for pass or the red LED will illuminate for fail. An audible buzzer will sound if the red fail LED illuminates.

If the resistance through the wrist band and person exceeds 35 meg ohms, the high red fail LED will light. If the resistance is below 750 kilohms, the low red fail LED will light. If the 9-volt PP3 battery falls below 6.5 volts during the test, the yellow battery low LED will light. E4Sure can be powered by a 9-volt PP3 alkaline battery.
