3.1 Testing Ports
Battery
-
The tester has four banana jacks which connect with A+/V+/V-/A-.A+ and A- ports are
connected with the positive and negative poles of the test objects, working as the current
channel in charging and discharging. V+ and V- ports are connected with the positive and
negative poles 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.
3.3 Input Power:
The tester works on a power supply of above DC 12V/3.5A and interface specification of
5.5/2.1 (inside positive and outside negative).

CC
–
constant current discharging
CP
–
constant power discharging
Ni
–
NiMH/NiCd charging
Li
–
LiPo/LiFe charging
Pb
–
plumbic acid battery charging
CV
–
custom constant voltage charging
PW
–
fixed voltage output (5V/2A)
The second line shows working process, working time (in minute) and capacity (automatic
switch between 0000mAh and 00.00Ah).
Working process reads OFF when the test stops and DSC or CHG in testing. It shows AT1 if
you choose automatic charging/discharging and 1 means the step 1 of current testing.
A short press on the
“SET”
button and the display changes to power and energy.
In automatic
“charging-discharging-charging”
test, you can check test results of each step by a
short press on
“INC”
or
“DEC”
buttons.
Press the
“ON”
button to start testing and one more press to stop.
You can open setting interface by press on the
“SET”
button for 2 seconds in the stop state
(This function is invalid when the tester being connected with the PC software).
4.3 Setting Interface
The cursor default is on mode setting. Press the
“SET”
button to move it to the value you want
to set up. One press on
“SET”
and the cursor moves one digital toward right. Press the
“INC”
and
“DEC”
buttons to modify the value. Press the
“ON”
button the move to the next item. It
will go back to the limit value if your setting exceeds the allowed range.
1) CC discharging
First line: mode and discharging current setting.
Second line: cut-off voltage (testing automatically stops when voltage reaches below this value)
and the maximum testing time setting (no time limit if being set 0).
2) CP discharging

First line: mode and discharging power setting
Second line: cut-off voltage (testing automatically stops when voltage reaches below this value)
the maximum testing time setting (no time limit if being set 0).
3) Standard charging
First line: mode and charging current setting. Modes include: NiMH, NiCd, LiPo, LiFe, Pb
Second line: batteries numbers (plumbic acid: 2V for each battery), charging time (no time
limit if being set 0) and auto mode setting:
²
NOR
–
normal mode, charging will finish soon.
²
AUTO
–
automatically finish the
“charging-discharging-charging”
process.
When cursor is on AUTO, a long press on
“ON”
and you will move to the second step of auto
discharging setting.
The first parameter: discharging current; the second parameter: cut-off voltage; the third
parameter: interval between step switches (a 5-10 minute waiting time is suggested in a switch
between charging and discharging to cool the battery).
4) Custom charging
First line: mode and charging current setting
Second line: CV voltage, cut-off current (testing stops when the voltage reaches below this
value, can be set above 0.06A) and automatic mode setting (same setting as standard charging).
5) Fixed voltage output
Select
“CHG-PWR”
for fixed voltage output and don’t need to set any other parameter. The
mode turns off if the current becomes 0 within 10 seconds of testing.
In setting mode, a long press on
“SET”
button to save data and return to testing interface.
When setting completes, press
“ON”
button on the testing interface and testing starts.
