OTHER FEATURES ---- automatic statistics of discharge capacity and discharge time; set maximum discharge capacity OAH and maximum discharge time OHP (to realize unattended aging experiments); with intelligent temperature-controlled fan; with powerfully serial communication function. PARAMETER ---- input voltage range DC 5v~30v; load voltage range DC 1.5v~25v; rated current 5A max; rated power 35W max; other displayed value: capacity, discharge time. PROTECTION ---- reverse connection protection; over-voltage protection (OVP); over-current protection (OCP); over-power protection (OPP); low-voltage protection (LVP); over-temperature protection (OTP). LOCKABLE CURRENT ---- with rotary coding potentiometer, can accurately adjust the current, accuracy can reach 0.01A; the current can be locked to prevent misoperation. DATA GROUP FUNCTION ---- can choose whether to add up the capacity value and running time of the previous stage. Features Simultaneous display of voltage and current and mAH data for easy viewing Can detect mobile power output mAH Multiple sets of test data are saved, power-down save function Does not affect data transmission Higher precision, the current parameters will not jump USB male and MicroUSB ports are dual-powered to detect MicroUSB line quality Current sampling 25 milliohms, less loss With precision current calibration, current accuracy is higher (it has been calibrated at the time of shipment) Performance parameters Input voltage: 3V-15V (actually within 15V) Voltage resolution: 0.01V Test current: 0.05A-3.50A Current resolution: 0.01A Capacity range: 0-19999mAH Accuracy: plus or minus 1% Line loss: about 0.1 ohm Test content: battery voltage, current, discharge capacity (total 10 sets of data) List 1x digital voltage measuring instrument
