## Description

parameters: 
 Operating voltage: DC 4.5 ~ 30V 
 Measure the voltage: DC 0 ~ 100V 
 Minimum resolution (V): 0.1V(when >10V) 
 Minimum resolution (V):0.01V(when  Measure current: 2A / 5A / 10A / 50A / 100A (> 10A, need external shunt) 
 Minimum resolution (A): 0.01 A 
 Operating Current:  Display: three 0.28 "LED digital tube 
 Display Color: Red + Red; Red + Blue (Dual Display) 
 Dimensions: 48 x 29 x 21 mm 
 Refresh rate: 500 ms / times 
 Measuring accuracy: 1% (± 1 digit) 
 Operating temperature: -10 - 65 ℃ 
 Humidity: 10 to 80% (non-condensing) 
 Working pressure: 80 to 106 kPa 
 
 wiring: 
 Black line (thin): vacant or buck circuit (module) is negative 
 Red line (thin): Power Supply + 
 Black line (thick): COM, common measurement 
 Red line (thick): PW +, measuring terminal voltage input positive 
 Yellow line (thick): IN + input + current 
 
 Please note: 
 The operating voltage must be DC 4.5-30V. 
 The ammeter can be connected only to the negative of the device. 
 ≤10A, built-in shunt, no need external shunt; > 10A, need external shunt. 
 When the black thin line free, it is better to use insulating tape around the exposed portion of the wire to prevent short circuits 
 If only be used as a voltmeter, connect together the yellow and black line. 
 
 Package Included: 
 1x digital amp volt meter

## Features

- Display voltage and current simultaneously(the current is measured in the negative rail)
- Ground wire of testing end and power supply temninal is the same wire; quick refresh of about 500 ms / times
- Require external power supply;With reversed connection protection
- 0.28" DC digital LED display in two colors (red+blue/red+red), bright LED, easy to read
- With built-in shunt,has voltage and current calibration potentiometers
