Portable Surge Protective Device Tester
FUNCTION SELECTION
FOR VOLTAGE-LIMITING SPDS (MOV-TYPE)
1 Standard Test: the break-over voltage and the leakage current are displayed. A buzzer will sound if the deviation
exceeds the default value by ± 5%.
2 Precise test to verify the current outputs (1mA) and test the break-over voltage: the constant current(1mA) outputs and
the break-over voltage will be continuously displayed.
3 Precise test for the leakage current: the break-over voltage is displayed first, then the 75% value of the break-over
voltage and the leakage current will be alternately displayed.
4 Customized test the leakage current by positive deviation: the 75% value of the break-over voltage and leakage current
will be alternately displayed. Press the TEST button to boost the voltage in increments of +1Ad (1Ad=0.293V); then the
value of leakage current under the boosted voltage will be alternately displayed with the Ad value.
5 Customized test for leakage current by negative deviation: the 75% value of break-over voltage and leakage current
displays alternately. Press the TEST button to reduce the voltage in negative increments of -1Ad (1Ad=0.293V), then the
value of leakage current under the boosted voltage will be alternately displayed with the Ad value.
FOR SWITCH-TYPE SPDS (GDT-TYPE)
6 Standard Test: boost the voltage at a rate of 100V/sec, and the voltage boosting progress bar is displayed. Finally, the
breakdown voltage of the Switch-type SPD will be displayed.
7 Precise Test: boost the voltage at a rate of 100V/sec, and the voltage boosting progress bar is displayed; next, the
breakdown voltage of the Switch-type SPD will be displayed; hold the TEST button to boost the voltage rapidly again at a
rate of 100V/sec until it reaches the point that differs by 100Ad (1Ad=0.293V) from the value previously tested. Then lower
the voltage boosting speed to 2Ad/sec. The highest voltage value finally shown in the DISPLAY is the breakdown voltage
of the Switch-type SPD.
THE DEFAULT VALUE OF BREAK-OVER VOLTAGE FOR MOV-TYPE SPDS
8 Set the default value of the break-over voltage: when the default value of the break-over voltage blinks in the DISPLAY,
※
Press TEST button to increase the value; hold the TEST button to increase the value rapidly.
※
Press FUNCTION SELECT button to save the value. Then the tester will return to testing standby status with 1 in the
display.
