The ZQ 0107 pointer frequency meter has a 144x144 mm front frame and a 90 degree dial. It is the same as the ZQ 0107 (see photo), except it is larger. It is designed for measurement of mains voltage frequency within five different measuring ranges (45-55 Hz, 48-52 Hz, 45-65 Hz, etc). Dial has to be exchanged, when the measuring range is changed. Meter consists of: power supply unit, measuring unit with microprocessor and instrument with moving coil. The meter is powered through measuring terminals. One of the following voltage ranges can be used: from 57V to 110V, 230V, 400V, 500V. Voltage range is factory preset according to customer order. ZQ 0107 is available also for mounting on ships.
