Battery Capacity Tester Electronic Load Power Tester Battery Discharge Meter 20A 200w Detector with EU Plug Specifications: The tester is an electronic load with a variety of discharge modes. It can be used in various battery capacity tests, power tests, support for connecting computers, and more extensions via online software. Power Supply: Dc 12V Voltage setting: 0.00-30.00V, the minimum step 0.01V Current setting: 0.1-20.00A Minimum step 0.01A (Automatic limit current when power is overrun ) Test mode: DSC-CC: discharge current is constant, used to test battery capacity or supply current. DSC-CP: dischage power is constant, used to simulate constant power equipment or test power Voltage test: 0.000-4.500V (low pressure) accuracy to 0.003V, error 0.5% 4.50V-30.00V(high presure) 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 of 0.001Ah 10Ah-100Ah, the resolution of 0.01Ah above 100Ah, the resolution 0.1Ah Dischage power: Max 200W. It should be controlled within 90% for a long time working. Connection: four-wire detection, voltage and current channel separate wiring, to ensure measurement accuracy. Lcd display: voltage, current, capacity, time so on test data. Computer Online: dedicated usb to TTL serial port (Mini usb port, not an ordinary usb cable) . curve plotting, automatic current test, calibration reference,upgrade equipment. Note: 1. Due to the light and screen difference, the item's color may be slightly different from the pictures. 2. Please allow 1-3cm differences due to manual measurement.
