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
