SEW ST-1520

SEW ST-1520

● Capable of measuring earth resistance and earth voltage.
● 2mA measuring current permits the testing of earth
resistance without tripping earth leakage current
breakers in the circuit under test.
● Auto power off function.
● 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.
● Timer for test function (count 3-5 minutes).
● Battery operated.
● Data hold function.
● Small and light weight.
● Calibration performed with supplied test leads.
