The TN277NZHP is an ideal tool for checking the presence of AC high voltages and AC low voltages in cables, wall outlets, fuses etc. It provides a non-contact detection for AC voltages from 50V ~132kV. It is also suitable for industrial, utility and mine safety applications.
2 ranges for selection ( 2 function buttons )
LOW :50V~1.5kV. Press the LOW button for low voltage detection.
HIGH : 1.5kV~132kV. Press the HIGH button for high voltage detection.
Off : Less than 5uA
Low voltage detection mode: Less than 40mA High
Voltage detection mode: Less than 40mA
Circuit test function
Press the Test button to make sure the whole circuit is working well before testing actual high voltage circuits.
