Product Review
Our "Watt's Up" model WU100 meter is a general purpose test, measurement and battery monitor and condition tester designed to be used in a wide range of RC, RV solar, wind, Airsoft DC applications. Connect between any power source (e.g., battery, charger, solar panel) and the load (e.g., motor, battery, inverter, amplifier, appliance, LED, circuit) that's using the power to be measured. This forces current through the meter so it can be measured. Has reverse connection protection. Current and voltage are directly measured and the six other measurements (e.g., power, Ah, Wh, peak current, etc.) are computed by the meter's DSP. No setup, programming or computer needed. Volts, Amps and Watts are continuously displayed. Ah, Wh, Amps peak, minimum voltage and peak Watts values are displayed sequentially in the "Data Queue" position at lower left corner of screen. Powered (~ 0.007A) by your circuit, so needs no batteries. Or eliminate circuit power draw with external 4 to 60 Volt DC source connected to meter's 3-pin socket. Typ. accuracy: 1% Volts, 1% Amps. Repeatable, high-resolution measurements. Accurately measures RMS value of time varying DC voltage. Built-in current shunt resistor's low 0.001 Ohm resistance so meter doesn't affect your circuit. Current only measured in one direction. From Source to Load through the black "negative" lead. Easily reset accumulated readings by adding a pushbutton switch to auxiliary power connector cable. Comes with 14 gage, 3.8" long, high-flex, high-temp. silicone insulated wires. Without connectors. Dimensions & weight: 2.8" L x 1.7" W x 0.83" D, 2.3 oz. 1.7 oz. with case removed. Full user's manual/tutorial online. Dust-proof plastic case: Black is opaque ABS, Blue is translucent K-resin. 1-year warranty against manufacturing defects. r2.2.2
