Meters for DC and AC Voltage or Current with Moving Coil and a Rectifier CQ
Meters with a moving coil and a rectifier are intended for measurement of AC currents or voltages in the frequency range from 40 Hz to 65 Hz (higher frequency range on request), where low meter consumption is required. The meters measure the mean value of rectified current or voltage. The scale is expressed in rms values at the sine form of the measured quantity. Distortion or deviation from the sine form of more than 1% entails additional errors. The scale is interchangeable. The accuracy class is 1.5.
Meters are available with different front frames:
CQ 0507 – 45 x 45 mm
CQ 0407 – 48 x 48 mm
CQ 0307 – 72 x 72 mm
CQ 0207 – 96 x 96 mm
CQ 0107 – 144 x 144 mm
CQ 2507 – 45 x 45 mm
CQ 2407 – 48 x 48 mm
CQ 2307 – 72 x 72 mm
CQ 2207 – 96 x 96 mm
CQ 2107 – 144 x 144 mm
CQ 3207 – 96 x 96 mm (4-stage selector switch is built in the meter for measurement of current in three individual phases)
Their dials can be 90 degrees in the CQ 0x07 and 240 degrees in the CQ 2x07.Special meters can also be made, according to you wishes.
