AC-DC Current Transfer Instruments
At power and audio frequencies, AC current measurements at highest accuracy are made using AC/DC current transfer instruments, of known AC/DC current differences.
SCL has set up calibration facilities for AC/DC transfer instruments. This new service has been accredited by HOKLAS. The details of the service are as follows:
Items, materials or products tested |
Specific tests or properties measured |
Best measurement capability expressed as an uncertainty or detection limits (where appropriate) |
|---|---|---|
| AC/DC Transfer Instruments | Calibration of AC-DC current difference for AC/DC current transfer instruments in the range 5 mA to 20 A and 40 Hz to 10 kHz. | 20 ppm |
For calibration fees, please contact Mr. Y.K. Yan at (852) 2829 4855 or ykyan@itc.gov.hk.
