  • The multimeter can clearly display voltage and current at the same time.
  • High precision, high reliability, suitable for high-end application.
  • With reverse protection, anti-not burned.



  • Measure voltage: DC 0 ~ 100V
  • Measure current: 0-50A
  • Operating voltage: DC 4 ~ 30V
  • Voltage error: ±0.1%
  • Current error: ±1%
  • External shunt specification: 75 mΩ
  • Operating current: <20mA
  • Refresh rate: about 300mS / times
  • Display: three 0.28" LED digital tube
  • Display color: A(red+red), B(red+blue)
  • Lead Length: 15cm
  • Dimensions: 48 x 29 x 22 mm, length X width X thickness
  • Opening Size: 46 x 27 mm
  • Net weight: 20g
  • Working Temperature: -10°C~65°C


  • Black line (thin): vacant or buck circuit (module) negative
  • Red line (thin): positive pole of power supply
  • Black line (thick): COM, common measuring terminal
  • Red line (thick): PW+, input terminal of measuring positive voltage
  • Yellow line (thick): IN+, the positive of current input
  • (Please refer to the wiring diagrams for more details)


  • The voltage between the thin red and thin black lines must be within DC 4.5-30V
  • The ammeter can only be connected to the negative of the device under test and can only test amp in positive direction
  • Exceeds 5A, long-term full load working continuously, we recommended test side of leads directly soldered to the socket
  • When black thin line vacant, it is better to use insulating tape around exposed part of wire to prevent short circuits
  • If just used voltmeter, we recommended yellow line and black line connected together to prevent ammeter's digit flashing
