Earth Resistance Tester 3-wire method
รายละเอียด:
| FEATURES : | |
| |
| ? Capable of measuring earth voltage. | |
| ? 2mA measuring current permits the testing of earth | |
| resistance without tripping earth leakage current circuit | |
| breakers in the circuit under test. | |
| ? The leads are supplied as standard accessories for | |
| simplified two-wire measuring system. | |
| ? 0? adjustment. | |
|
| ? Data hold function. | |
|
| ? Battery operated. | |
|
| ? Battery life indicator. | |
|
| ? Designed to meet EN 61010-1 CAT III 200V. | |
| IEC 61557-1 IEC 61557-5 EN 61326-1 | |
| ? Calibration performed with supplied test leads. | |
