## Description

From the manufacturer Digital Voltmeter Ammeter By Robotbanao DESCRIPTION This is Red-Blue LED Digital Dual DC 100V 100A Ammeter Voltmeter. This meter will measure up to 100 VDC with a 0.1-volt resolution. One thing to note is, this meter has 2 wiring harnesses. One harness is to provide power for the meters, that’s the 2 poles with a RED and a BLACK lead. Small size, portable, the magnitudes of voltage and current are displayed on the same screen at the same time. Digital Voltmeter is an instrument used to measure the electrical potential difference between two points in a circuit. Digital Voltmeter displays the voltage readings of a circuit numerically. APPLICATIONS Digital Voltmeter is used to know the actual voltage of different components. DVM is widely used to check if there is power in the circuit, such as the mains outlet. Knowing the voltage across a circuit, current can be calculated. DIGITAL VOLTMETER AMMETER SPECIFICATIONS Operating Voltage(VDC) - 5V Current Consumption (mA) - 60 Test Voltage (V) : 0 - 100 V Test Current (A) - 1 to 100 Amp Refresh Speed (ms) - 500 (one time) Operating Temperature (°C) : -10 to 60 Dimensions (LxWxH) mm - 48 x 29 x 21 APPLICATION FEATURES It measures up to 100V and 100A DC. Very handy and small in size. It requires a power supply of 5V. 100% Brand new and high quality. IN THE BOX 1 x Dual LED Panel Ampere Voltage Meter.

Review: Good product for creating 3 digit DMM! - Negative voltage cannot be measured and return path current you cannot check ( these two things present it will be a higher cost in market) other than that very good product. If you want to measure current then connect the ammeter in positive side. Worth for price and delivered on time. I don't know current is not showing while taking load. But it's okay to me. I would like to measure only voltage ⚡.
Review: Good Device if connected correctly. Calibration is needed for amps. - The product is very good. You may find a slight difference in the amps but that can be calibrates by turning the star screw at the back labelled I. The screw labelled V is for votage, and that will mostly not need calibration. When I received the device, the amps were high by 800 mA (0.8A). After calibrating the amps is now high by only 30mA (0.03A). PS. Its not possible to calibrate the Amps to exact 0.000 if you do so the actual reading during a load test will show a lesser value. The lowesr value the amps can be calibrated to is 0.03A and the reading will always show 30mA - 60mA more. At 0.00A the reading will show 0.03A and around 1.00A the reading will show 1.06A The Meter can be connected in 2 correct circuit methods. The Thick Black wire is the Neutral Line The Thick Red wire is used to check the Amps The Thin yellow wire is to check the Volts The thin red wire is to power the meter. The thin Black wire is also neutral line but is to be only used when the meter power source is seperate from the load power source. If power source is same DO NOT CONNECT this wire any where. Also the Amp meter wire has to be connected in series AFTER the load, NOT Before else it won't work. 1. Correcting to the same power source as the Load. Here the power source has to be 4V to 30V else the meter will not work. This will help you measure voltage from 4V to 40V. Below 4V the meter will go off. 2. Correcting to a seperate power source from the Load. Here the power source for the meter has to be 4V to 30V else the meter will not work. This will help you measure voltage from 0V to 40V.
