DC0-100V 1A 10A 50A 100A Digital Voltmeter Ammeter 2 In1 Multimeter DC4-30V Voltage Ampere Meter Volt Amp Gauge Panel Dual Display

With small sized x 29 x 21 mm ), wide measuring range(dc 0-100v; 0-10A) and high accuracy percent (± 1 digit))

Display Voltage and current simultaneously in different colors, red for Voltage, Blue for current (the current is Measured in the negative rail)

Require external power supply; with reversed connection protection

Ground wire of testing end and power supply terminal is the same wire; quick refresh of about 500 MS/time

With built-in shunt, has Voltage and current calibration potentiometers

Features:

Operating voltage:DC 4.5 - 30V

Measure voltage: DC 0 - 100V

Minimum resolution(V): 0.1V

Measure current :10A (measure directly,built-in shunt)

Minimum resolution(A): 0.01A

Operating current:

Dimensions: 48 x 29 x 21mm

Mounting cutout: 45.5 x 26.5mm

Refresh rate: about 500mS / times

Measure accuracy: 1% (± 1 digit)

Operating temperature: -10 to 65° c

Operating Humidity: 10 to 80% (non-condensing)

Applications:Suitable for automotive/electric cars/motorcycles battery monitoring or other products voltage current measurement

Wiring: Black line (thin): vacant or buck circuit (module) negative

Red line (thin): power supply+ Black line (thick): COM, common measuring

Red line (thick): PW+, measuring terminal voltage input positive

Yellow line (thick): IN+, current input+ (Please refer to the wiring diagrams for more details)

Notice: 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 10A below ammeter (include 10A), built-in shunt, does not require external shunt

When the black thin line vacant, it is better to use insulating tape around the exposed part of the wire, to prevent short circuits If just be used as a voltmeter, it is recommended that the yellow line and the black line were connected together, to prevent the ammeter digital flashing

Package include: 1x Digital Volt Ampere Meter
