Insulation Resistance Testers
The Laboratory offers calibration for DC Insulation Resistance Tester with output test voltage not exceeding 1 kV for resistance range from 0.1 MΩ* to 600 GΩ or 5 kV for resistance range 10 MΩ to 600 GΩ.
The tester under test will be calibrated against the high-valued standard resistors of the Laboratory. At each calibration point the indication on the tester will be compared with the value of the applied resistance and the output voltage of the tester will also be measured.
As test leads that are used with a tester may have leakage resistance, it is advisable that the client submit these leads for test together with the tester.
Calibration charges
| Fee in HK$ | |
|---|---|
| Calibration of a single range DC insulation resistance tester for one output voltage (normally not exceeding 5 test points). | $2150 |
| Calibration for each additional range at the same output test voltage (5 test points). | $850 |
| Calibration for the same range at a different output test voltage (5 test points). | $850 |
(Note* Resistance range was extended to cover 0.1 M£[ to 1 M£[ in February 2008.)
