Digital Earth Resistance Testers ST-1520, 085282731888
Ï Capable of measuring earth resistance and earth voltage.
Ï 2mA measuring current permits the testing of earth
resistance without tripping earth leakage current
breakers in the circuit under test.
Ï Auto power off function.
Ï The timer operates automatically for about three to five minutes
when the " PUSH BUTTON SWITCH" and " TIMER ON BUTTON"
are pressed together. This will keep test " ON" for the duration of the
timer.
Ï Timer for test function ( count 3-5 minutes) .
Ï Battery operated.
Ï Data hold function.
