Withstanding Voltage Testers
The Laboratory offers calibration for withstanding voltage testers with sinusoidal output voltages (50 Hz) not exceeding 11 kV (r.m.s. value). The calibration will normally include measurement of output voltages and test for leak current detection accuracy. Clients may be required to provide appropriate loading resistors for the leak current test.
For calibration of testers having additional functions, or higher output voltages additional charges will be quoted upon request.
Calibration charges
| Fee in HK$ | |
|---|---|
| Measurement of output voltages from a Withstanding Voltage Tester (normally for not more than 2 output ranges). | $2260 |
| Measurement of output voltages from the same equipment for each additional output range. | $570 |
| Leak current detection accuracy test for the same equipment (normally for not more than 7 leak current settings). | $2260 |
| Leak current detection accuracy test for each additional leak current setting. | $180 |
