DROK DC 0-300V Amp Volt Digital Multimeter, 0-20A Five-wire Ammeter Voltmeter, Digital Tester Multimeter with 0.39" Voltage & Current Dual LED Display, Electronic Meter Panel Gauge for Car Auto

Description

Parameters:
Voltage Measuring Range: DC 0.0-300V
Voltage Operating Range: DC 3.5-30V
Voltage Resolution: 0.1V under 100V, 1V over 100V
Current Measuring Range: 0.0-20.0A
Current Resolution: 0.01A under 10A, 0.1A over 10A
Power Supply Voltage (non-isolated meter): DC 3.5-30V (wide range); Note: the max input voltage can t exceed 30V, or the meter will burn.
Isolated Meter (isolated power supply meter): DC 8-18V
Working Current: <20mA
Display: 0.39" LED
Measuring Velocity: ≥500mS each time
Accuracy of Measurement: 1% (±1 digit)

Connecting Method:
1.Power Supply of Meter:
Thin Black Wire: Negative pole of power supply
Thin Red Wire: Positive pole of power supply (Note: voltage between thin black wire and thin red wire can t exceed 30V.)
Isolated Meter (isolated power supply): Power supply terminal and test terminal are totally insulated and isolated each other; several meters can share one power supply, and don t worry any interference caused by sharing power supply;
it is suitable for factory aging test, test bed or any other devices which need many meters; power supply voltage: DC 8-18V
2. Test Terminal:
COM: Common terminal of test terminal
V+: Input terminal of testing positive voltage
A+: Input terminal of testing positive current
( This meter adopts common-ground design that earth wire of measuring terminal is interlinked with earth wire of power supply, so A+ only can be connected bewteen the tested device negative pole and power supply negative pole.
the meter will be burnt if connected wrong.)
Note: If the meter is just used as voltmeter, it is suggested that the yellow wire and black wire are connected together.

Package Included:
1 x DC meter
