详细内容
- Capable of measuring earth voltage.
- Data hold , MAX / MIN function.
- Auto power off function:
The timer operates automatically about
3 minutes when the " Test Button Switch "
are pressed to keep the tester power on. - 2mA measuring current permits earth
resistance tests without tripping earth
leakage current breakers in the circuit
under test. - In addition to the facility for precision
measurement, test leads for simplified two
wire measuring system also supplied as standard
accessories.(unit can be hung from the neck for
simplified measurement). - Automatic warning when resistance of auxiliary
earth. Spikes is in excess of tolerance. - Designed to meet IEC1010-1 safety standard.
