The battery tester is deigned for measuring the internal resistance and output voltage of lead storage cell, nickel-cadmium, lithium-ion and nickel metal hydride batteries. Features: On-line testing without shutting down battery AC four-terminal method to eliminate lead resistances and contact resistances, which provides the most accurate results Dual LCD display simultaneously shows the internal resistance and voltage of the battery Built-in data logger Pin type and alligator type 4-terminal Kelvin leads for quick and accurate resistance Comparator function with storage of up to 99 sets of resistance and voltage values for battery deterioration characterization Memory capacity to store up to 999 manually stored data points or up to 9600 points stored using interval data logging RS-232 data port to upload data to your PC Low battery indicator built in zero adjustment Audible tone for warning and failure alerts (can be disabled) Green, yellow and red LED indicators Specifications: Temperature coefficient: (0.1% reading 5digits)/C Measuring currency frequency: 1kHz 10% Measuring burden voltage: 1.5mVAC Resistance Ranges: Resolution Approximate Measurement Current 40mΩ 10μΩ 37.5mA 400mΩ 100μΩ 3.75mA 4Ω 1mΩ 375μA 40Ω 10mΩ 37.5μA Resistance accuracy: (1% reading + 10digits) Voltage Ranges: 4V with 1mV resolution 40V with 10mV resolution Accuracy: (0.1% reading 6 digits) Conditions to guarantee accuracy: Temperature: 23 C Humidity: 80% RH or less (non-condensing) Zero adjustment: after zero adjustment for each range Maximum input voltage: 50VDC (no AC voltage) Power: 6 AAA batteries Maximum power consumption: 1.0vA Battery Life: approximately 7 hours Dimensions: 9.75″ x 4″ x 1.75″ (250 x 100 x 45 mm) Weight: 17.5oz (500g) including batteries Supplied with: Owner’s manual Hard blown carrying case RS-232 to serial (DB9) PC interface cable Windows 95/98/NT/2000/ME/XP
