DescriptionAccurate & precise 0.01A current and 0.01V voltage resolutions. Measures peak Amps, peak Watt and minimum voltage.This minisize watt meter can worked well like these larger size one, sometimes even more better.Feature-Color: As Shown. - Material: Plastics+Electronic Components+LCD. - Size: 8.5 x 5 x 2cm. - Current: 0-100A resolution 0.01A persistent current 50A. - Voltage: 0-60V resolution 0.01V. - Capacity Accumulation Function: 0-65AH. - Power Accumulation Function: 0-6554WH. - Voltage Peak Detection Function. - Rugged-handles 50A continuous and 100A peak at 60V. 14ga, super fine stranded, high temperature, silicone rubber insulated wire.- Small & light with a tough plastic case available in several colors.- Acts like a wire, so doesn't affect model's performance.- Precision Alu-Chrom current sensing resistor, with only 0.001 ohms resistance and circuitry that draws only 7 mA.- Powerful, 8 MIPS micro-controller.
