 1000 V ac/dc

 600 V ac/dc

 Indefinitely for voltages up to 240 V

 For voltages between 240 V and 600 V the duty cycle is 30 s on / 300 s off

 For voltages above 240 V the tester must connect to a voltage source only for a MAXIMUM of 30 s and then disconnect for a MINIMUM of 300 s

 LEDs turn on at voltages > 30 V ac/dc ± 35 %
