Latest circuit design permits the instrument to operate with a minimum of influence from ground voltage and ground resistance of auxiliary ground spikes
Ground resistance values can be read directly from the scale
Capable of measuring ground voltage
2mA measuring current permits ground resistance tests without tripping ground leakage current breakers in the circuit under test
Lead wire connection to C and P terminals and proper auxiliary earth resistance can be checked
Designed to meet IEC61010-1 Cat. III 300V
New shock resistant case material is also dust and drip proof
Includes one set of color-coded test leads, one set of auxiliary ground spikes, one simplified measurement probe, batteries, neck strap, hard carrying case and instruction manual
