Measures 0 to 60 volts. Works on 12, 24, 36 and 48 volt battery bank systems. Precision Alu-Chrom current sensing resistor, with resistance of only 0.001 Ohms and circuitry drawing only 7 mA. This is the all-in-one meter: a power meter, voltmeter, ammeter, ammeter and energy meter. A digital LCD display gives clear and accurate readings. Perfect troubleshooting tool: It is essential for analyzing, testing and troubleshooting any DIY DC power supply project. The professional RC power meter is a great addition to your RC hobby systems, DC circuits, solar system, boat/RV and backup battery!Feature:100% brand new and high quality.Digital LCD display gives clear and accurate readings.Handles up to 100 amps intermittent and 50 amps on duty continuous.Connecting the load to the battery allows a real-time reading of the battery charge.Handles from 0 to 60 volts. Works on 12, 24, 36 and 48 volt battery bank systems. Extremely low power consumption of 7mA. More efficient than any LED meter. Measure energy (wh), charge (ah), power (w), current (A) and voltage (V). Accurate and accurate current resolutions of 0.01 A and 0.01 V. Measures for peak amps, peak watts (except Doc Wattson) and minimum voltage (sag). Heavy duty - handles 50A continuous and 100A peak at 60V. Acts like a thread so as not to affect the performance of the model. Precision Alu-Chrom current sense resistor, with resistance of only 0.001 Ohms and circuitry drawing only 7mA. Uses DSP to increase ADC resolution and differential measurement amplifiers to increase noise immunity. Features :Blue colorVoltage: (0)V-4V-60V 0.01V (resolution).
