3. Connecting patterns
3.1 Testing Ports
The tester has four banana jacks which connect with A+/V+/V-/A-. A+ and A- ports are
connected with the positive and negative ends of the test objects, working as the current
channel in discharging. V+ and V- ports are connected with the positive and negative ends of
the test objects, working as the voltage channel in voltage tests. This way of using four
individual cables will help eliminate the effect of wires on the test result and improve the test
precision.
3.2 PC Connection
The tester can be connected with a computer through a designated USB-TTL cable (with aerial
socket).
3.3 Input Power
The tester works on a power supply of DC 12V, 1A and interface specification of 5.5/2.1
(inside positive and outside negative).

4.2 Testing interface
The first line shows testing mode (CC/CP), voltage and current. Testing modes include:
CC: in this mode, the tester supports discharging at a constant current. It allows you to set
discharging current and cut-off voltage. Discharge stops when voltage in tests reaches below
cut-off voltage. Discharge stops automatically when setting time ends. Using this mode you
can test output current of power supplies and battery capacity. When testing power supply, you
can either choose automatic stop or set cut-off voltage a minimum value to turn off auto stop.
CP: in this mode, the tester supports discharging at a constant rating. It allows you to set
discharging power and cut-off voltage. Discharge stops when voltage in tests reaches below
cut-off voltage.
The second line shows working state (it shows OFF when the tester stops working and it turns
DSC at working), working time (minutes) and capacity (automatically switches between
