2 FEATURES AND SPECIFICATIONS
2.1 Features
 Measures energy (Wh), charge (Ah), power (W), current (A) and voltage (V)
 Connector to use an optional receiver battery for measurement down to 0 V
 Accurate & precise – 0.01 A current and 0.01 V voltage resolutions
 Measures peak Amps, peak Watts (except for Doc Wattson) and voltage
minimum (sag)
 Rugged – handles 50 A continuous and 100 A peak at 60 V
 14 ga., 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
 Uses DSP to increase ADC resolution and differential measurement amplifiers to
increase noise immunity
 Factory calibration stores constants in EEPROM to compensate for component
tolerances
 Powerful, 8 MIPS micro-controller
 Made in USA to ISO 9001:2000 quality standards
 One-year warranty and complete user manual
