|
| |
|
| • |
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 529 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. |
