Feature

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

Description

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: <20mA Display color: Red and Blue (two-color display)
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
