Description <br> Brand new and high quality. Digital LCD screen gives clear crisp number readings. Handles up to 100 amps intermittently and 50 amps continuous duty. <br> Connecting load end to the battery provides real-time battery charging reading. Handles 0 to 60 volts. Works on 12, 24, 36, and 48 volt battery bank systems. Extremely low power consumption of 7 mA. More efficient than any LED meter. Measure energy(wh),charge(ah), power(w),current(A) and voltage(V). <br> Accurate precise 0.01 A cuurrent and 0.01 V voltage resolutions. Measures peak Amps, peak Watts(except for Doc Wattson) and Voltage minimum(sag).Rugged- handles 50A continuous and 100 A peak at 60V. <br> Acts like a wire so doesnt affect models performance. Precision Alu-Chrom current sensing resistor, with only 0.001 Ohms resistance and circuitry that draws only 36 mA. USes DSP to increase ADC resolution and differential measurement amplifiers to increase noise immunity. <br> <br> Voltage:(0)V-4V-60V 0.01V (Resolution). <br> Current:0-100 A peak 0.01A (Resolution). <br> Power:0-6554 W 0.1W (Resolution). <br> Charge:0-65 Ah 0.001Ah (Resolution). <br> Energy:0-6554 wh 0.1 Wh (Resolution). <br> Measurement Update period:400mS. <br> Signal Sampling Rate:sample/s. <br> Data Queue Sequence time: 2 seconds. <br> In Circuit Resistance:0.001 Ohms. <br> Operation Current: 36 mA. <br> Material:plastic <br> colour:blue <br> <br> Package Contents: <br> 1 x Watt Meter <br> <br> Only the above package content, other products are not included. <br> Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. <br>
