Compact size, light weight and portable, wear and can provide long sercive time. Large LCD display, you can see the voltage, current, capacity, time, power, energy and other test data clearly. 20A discharge, the maximum discharge power is 200W. Four-wire detection, voltage test and current channel are separate wiring, to measurement accuracy. 3 working modes settable design, you can set -CC, -CP according to your demands. With multiple discharge mode, suitable for all kinds of battery capacity test and powersupply test. Support c-omputer online control, curve plotting, calibration benchmarking, firmware upgrade, cycle discharge etc. Name: Battery Tester Model: -A20H Configuration: standard configuration EU-Plug Voltage setting: Discaharge: 0.00-30.00V, the minimum step 0.01V Current setting: Discharge: 0.10-20.00A Minimum step 0.01A (automatic limit current when power is overrun) Mode setting: -CC: the discharge current is constant, it can be used to test the battery capacity or powersupply current; -CP: the discharge power is constant, it can be used to constant power equipment or test the power of powersupply Voltage test: 0.000-4.500V (low pressure gear) accuracy to 0.003V, error 0.5%; 4.50V-30.00V (high presure gear) accuracy to 0.01V, error 0.5% Current test: 0.10-20.00A, accuracy to 0.01A, error 0.5% Capacity test: 10Ah, the resolution is 0.001Ah; 10Ah-100Ah, the resolution is 0.01Ah; above 100Ah, the resolution is 0.1Ah Standard configuration: 2000g / 4.41lb Note: The discharge current is limited by max power, less than 20A when above 10V, less than 10A when above 20V.
