Bright blue backlit LCD display, easy reading. 12 gauge wire take higher volt and current. It is indispensable for analyzing, testing and troubleshooting any DIY DC power project. Very accurate in giving DC volt, ampere and wattage Operates from 8V to 60V or 0V to 60V with optional auxiliary battery. Measures 0-200A, resolution 0.01A; Measures 0-60V, resolution 0.01V; Measures 0-6554W, resolution 0.1W; Measures 0-65Ah, resolution 0.001Ah; Measures 0-6554Wh, resolution 0.01Wh Measuring Current (A), Voltage (V), Watts (W), Amp-hours (Ah), Watt-hours (Wh), Peak Amps (Ap), Minimum Volts (Vm), Peak Watts (Wp). Widely application battery tester, can test Solar Power batteries and chargers Multifunctional Tester: Evaluate RC battery charging efficiency. Measure power and energy consumption of any battery powered device. Predict model airplane flight time,Choose the best propeller/most efficient motor .Check for wiring and connector power loss.Ensure peak currents are safe for motor, ESC & Battery as well as wiring and connectors Notice: This watt meter was designed to be safe in systems unsing less than 60V and carrying current up to 200A. DO NOT EXCEED THE LIMITES This device only requires a tiny 7mA draw to operate, there will be no significant reduction in your power production during usage.

Conection:
Connect "SOURCE" Red wire to positive(+) and Black to Negative of battery or any DC electricity source.
Similarly,"LOAD" wires should be connected to any DC electricity based load.
Once there is power flowing through, the device will initialise and show you a full range of ratings including:
Current (Amps/A) at the present moment
Voltage (Volts/V) at the present moment
Power (Watts/W) at the present moment
Total Amps (Amp hours/Ah) since device initialised
Total Power (Watt hours/Wh) since device initialised
Highest Voltage Maximum (Vm) since device initialised
Highest Power Peak (Watt Peak/Wp) since device initialised
Highest Current Peak (Amp Peak/Ap) since device initialised
