10) Four lines: voltage and current channels separated for high test accuracy
11) LCD display: voltage, current, time, capacity, and etc.
12) PC connection: the tester can connect to a computer through a designated USB-TTL cable
for more functions, like graphs, calibration, firmware upgrade, and test circulation.
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 charging and 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.
3.3 Input Power:
The tester works on a power supply of DC 12-19V, 4A or above and interface specification of
5.5/2.1 (inside positive and outside negative).
4. Display and setting
4.1 Buttons
4.1 Buttons
SET —— setting knob (rotate to left/right and press)
ON —— start
4.2 Testing interface
The first line shows testing mode, voltage and current. Testing modes include:
²CC –constant current discharging
CP –constant power discharging

²Ni –NiMH/NiCd charging
²Li –LiPo/LiFe charging
²Pb –plumbic acid battery charging
²CV –CC-CV charging
The second line shows working state (it shows OFF when the tester stops working and it turns
DSC or CHG at working. It reads ATI when you choose automatic
charging-discharging-charging mode, and 1 refers to current working step), working time
(minutes) and capacity (automatically switches between 0000mAh, 00.00Ah and 000.0Ah).
A short press on the SET”button can switch between power (W) and capacity.
In the automatic charging-discharging-charging”mode, you can check testing result of each
step by rotating the SET”knob.
Open the testing interface and press ON”button to start testing and press again to stop it. In
the halted state press SET”knob for two seconds or longer to open the setting interface (this
function disabled when the tester connects to a computer).
4.3 Setting interface
The cursor sets automatically on the testing mode and you can move it to the option you want
to change. One press on the SET”knob to move one step to right. Rotate SET”to left and
right to change the parameter. The parameter will change automatically if parameters set
exceed limitation. Press the ON”button to switch to next setting option.
1) Discharging at a constant current –DSC-CC
The first line shows testing mode and discharging current.
The second line shows cut-off voltage (testing stops automatically when voltage reaches below
the set parameter) and the testing time (0-999 minutes, no limitation when it’s set 0).
2) Discharging at a constant power –DSC-CP
The first line shows testing mode and discharging power.
The second line shows cut-off voltage (testing stops automatically when voltage reaches below
the set parameter) and the testing time (0-999 minutes, no limitation when it’s set 0).

3) Standard charging –CHG
The first line shows testing mode and charging current. Modes include: NiMH, NiCd, LiPo,
LiFe, Pb.
Second line: batteries numbers (for plumbic acid batteries, each battery counts 2V), charging
time (no time limit if being set 0) and auto mode setting:
²NOR –normal mode, testing stops when charging completes.
²AUTO –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
automatic discharging and it allows you to set discharging parameters.
The first parameter: discharging current; the second parameter: cut-off voltage; the third
parameter: waiting time between step switches (a 5-10 minute waiting time is suggested
between charging and discharging to cool the battery).
After completes settings, press SET”knob for a long time to save data and return to the
upper-level interface.
3) CC-CV charging
The first line shows testing mode and charging current.
The second line shows constant voltage, cut-off current (charging stops automatically when
current reaches below the set parameter, it can be above 0.06A) and the automatic mode setting
(same as in the standard charging).
During setting a long time press on the SET”knob allows you to save data and returns to the
testing interface. Press the ON”button to start testing.

5. Precautions
1) Positive and negative connections should not be reversed.
2) Always use the tester within the allowed range.
3) The maximum charging voltage should be set below power voltage–2V.
4) For batteries with a voltage larger than 10V, the maximum charging current should be lower
than power current-0.5A.
