MH10 is an electronically controlled miniature instrument, in which the high-voltage insulation resistance test has 4 rated test voltages to measure the insulation resistance. Suitable for measuring the insulation resistance of various electrical equipment and insulating materials such as motors, cables, switches, electrical appliances, etc. and for maintenance, repair, test and verification of various electrical equipment. The rated output voltage can use the function knob, MH10 is at 100V, 250V, 500V, 1000V. High pressure indication: The LED lamp (HV ON) and the "HV" on the left of the display indicate the high pressure output in the instrument and the danger of shock. The operator should pay special attention to safety. Measuring range MH10 is 0.1-1999M, and the range is changed manually. AC voltage range 1~750V, AC voltage frequency 40~70Hz.
