Item Type: Multimeter Model: DM100C Material: ABS Power Supply: 2 X AA 1.5V (Battery Not Included) Purpose: Electricity numerical measurement Main Functions Model: DM100CRangeAccuracy DC Voltage0~999.9V(1.2%+3) AC Voltage0~750V(1.5%+3) DC Current0~10A(1.0%+3) AC Current0~10A(1.0%+3) Range GearHand?automatic integration (auto range + manual range) Display Count1000 count Screen DisplayReverse display VA screen, analog bar + digital dual display True RMS1kHz AC Frequency MeasurementThe frequency value of the current voltage is displayed at the same time as the AC voltage is 0-1kHz. V.F.CFrequency conversion voltage measurement Frequency response: 40Hz-400Hz true RMS. Fuse Alarm600m/A10A current gear. After the fuse is blown, the screen prompts FUSE and buzzer alarm. Wrong Plug AlarmThe anti-burning alarm when the meter pen is incorrectly inserted can effectively prevent the meter from being burnt out due to the incorrect operation of the current gear.
