I.Introduction:
| ?Capable of measuring earth voltage. |
| ?Data hold 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. |
| ?Automatic warning when resistance of auxiliary earth spike is in excess of tolerance. |
| ?Designed to meet IEC1010-1 safety standard. |
| ?Zero ohm adjustment. |
