Megohmmeter М1628
The M1628 megohmmeter is used to measure for a short time (up to 1 minute) the insulation resistance of AC and DC networks that are under operating voltage, including those that have a galvanic connection to the AC network through semiconductor rectifiers, as well as de-energized DC networks and alternating current. Megohmmeter М1628.1 with additional device Р1828.1 in a splash-proof housing is designed to measure high electrical resistances to direct current, mainly insulation, electrical wires, cables, windings of electrical machines. Megohmmeter М1628 technical characteristics: frequency 50/400 Hz, measurement range from 0 to 5 megohm, voltage of the monitored network 220v Weight of the indicating device 1 kg, Weight of the additional device 1.8 kg. The overall dimensions of the indicating device are 120 × 120 × 126 mm. Measurement range - from 0 to 2 MΩ; from 0 to 5 MOhm.
