Soft Case Model
- 3-Pole and 2-Pole Earth Resistance
- The latest circuit design permits the instrument to operate with the minimum of influence from earth voltage and earth resistance of auxiliary earth spikes
- Dust and drip proof (designed to IEC 60529 IP54)
- Earth resistance value can be read directly from the scale
- Designed to meet IEC 61010-1 safety standard
- Capable of measuring earth voltage
- Small and lightweight. Shock-resistant new case material
- 2mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test
- Lead wire connection to C and P terminals and proper auxiliary earth resistance can be checked by “OK” lamp
Lead wire connection to C and E terminals is good when “OK” lamp is illuminated
