High-voltage Voltmeter
DC voltmeters with measuring ranges from 1 kV to 100 kV will be calibrated by comparing their readings with the known values of applied high voltages.
Low-voltage voltmeters, and detachable high-voltage probes for range extension may be calibrated together as a single high-voltage voltmeter.
Customers may be required to provide appropriate adaptors if their equipment cannot be connected directly to the Laboratory's measurement system.
For single-range voltmeters, calibration will be made at cardinal points (maximum 5 points).
For multi-range voltmeters, the basic calibration will include measurements at full range for each range and linearity check on one basic range. Linearity check on additional ranges may be offered at extra cost.
