MESTEK DM100 Digital Multimeter Maintenance Tool - Black

parameter:

Battery measurement: 0~1 5V (discharge current about 40mA); 0~9V (discharge current about 20mA)

Buzzer detection: 2kHz/2.7kHz/3V (can detect active or passive small horn buzzer)

True RMS: 1kHz

AC frequency measurement: measure the AC voltage and display the frequency value of the current voltage

High-speed sampling: sampling rate 10 times per second

V.F.C: Variable frequency voltage measurement, frequency response: 40Hz 400Hz true RMS (VFC: 2KHz attenuation 3dB)

Fuse alarm: 600mAV10A current gear insurance ratio is blown, the screen will prompt FUSE and buzzer alarm

Wrong insertion alarm: The test pen is inserted wrongly and the anti-burning alarm can effectively prevent the meter from being burned out due to the misoperation of the current gear. When the wrong plug is inserted, it will display LUSE and buzzer alarm.
