4.2 Testing interface

The first line shows mode (CC-constant current), voltage, and current.

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 auto test of “charge-discharge-charge”, you can check test results of each step by spin the

“SET” knob.

Press the “ON” button to start discharging test (shows DSC) and one more press to stop (shows

OFF).

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

set up. Spin the “SET” knob to change parameters selected by the cursor. It will go back to the

limit value if your setting exceeds the allowed range. Press “ON” button then move to the next

item.

1) DSC-CC (Constant current discharge)

First line: mode and 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) DSC-CP (constant power discharge)

EBC-A40L User Manual

First line: mode and 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) CHG-CV (constant voltage-current charge)

First line: mode and current setting.

Second line: constant voltage, cut-off current (testing automatically stops when current reaches

below this value; can be set above 0.1A), and the auto mode setting:

NOR —— normal mode，testing stops when charging finish.

AUTO —— automatically go through the “charge-discharge-charge” round test.

Put the cursor on AUTO and a long-time press on the “ON” button can lead to the setting of

auto discharging parameters:

The first parameter is discharging current, and the second the cut-off voltage, the third is the

waiting time for step switches (you are suggested to wait for 5-10 minutes between charging

and discharging for the battery cooling).

After you finish setting, press the “SET” button for a long time to return to the previous setting

interface.

Press “SET” button for a long time in the first-level setting interface to save data and go back

to testing interface.

After finish setting, press “ON” button to start testing.

4.4 Setting examples

1) Discharge setting (discharge the Lithium battery from 3.7V to 2.8V at 5A)

2) Charge setting (charge the Lithium battery from 3.7V to 4.2V at 2.5A, cut-off current is

0.11A)
