Accessories: Blank covers types Q72, Q96, Q144
Blank covers are typically applied to cover panel cut-outs provided for later extension of the switchboard.
The blank covers consist of a standard bezel with spring clamp for mounting in the panel, mounted with a white, opal PVC
plate instead of glass. (Depth behind panel: Approx. 12 mm).

Application: Measurement of AC currents and AC voltages, adjusted for frequency range
16..65Hz. Calibration for other frequency ranges (see page 2). The instruments
measure true R.M.S.
Working range: Ammeters are designed with a 2 times overload range. The instruments will
withstand starting currents up to 10 times normal load for 5 secs and 5 times
continuously
Scale range: The scale is standard designed with a 2 times overload range (non-standard scale
