FEATURES:
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.
