4. Enstalasyon
- Koneksyon pouvwa: Connect the tester to a 5V DC power source using one of the two Type-C interfaces. An adapter and cable are typically included.
- Ensèsyon batri: Insert flat-top 18650 batteries into the designated battery holders (3, 4, 5, 6). Ensure correct polarity (+ and -). The tester supports flat-top 18650 batteries.
- Estabilizasyon: After installing a battery, allow a few seconds for the voltage and internal resistance readings on the display to stabilize before proceeding with tests.
5. Operasyon Enstriksyon
The tester allows for independent operation of its four channels.

Figi 4: Display and control buttons. This image provides a detailed view of the tester's screen and the four control buttons located below it, used for navigation and operation.
5.1. Basic Navigation and Channel Selection
- Sèvi ak la Channel /CHN Key (16) to switch between the four independent channels (CHN 1 to CHN 4).
- La Menu /M Key (13) is used to enter or exit menu settings.
- La Adjust /S Key (14) is used to change values or select options within a menu.
- La Start/Stop /R/S Button (15) initiates or terminates a test cycle.
5.2. Automatic Charge and Discharge Cycles
The tester supports fully automatic charging and discharging cycles (1-9 cycles adjustable in auto mode).
- Select the desired channel using the Channel /CHN Key.
- Peze a Menu /M Key pou antre nan seleksyon an mòd.
- Sèvi ak la Adjust /S Key to select 'AUTO' mode.
- Adjust the number of cycles (LOOP: 1-9) using the Adjust /S Key si sa nesesè.
- Peze a Start/Stop /R/S Button to begin the automatic cycle. The charging process automatically stops when the battery is full.
5.3. Internal Resistance Measurement
The device utilizes the DC two-wire method to provide reference internal resistance values.
- For the most accurate reading, measure internal resistance when the battery is fully charged.
- The internal resistance value is displayed as 'mR' on the screen (5).
5.4. Setting Stop Discharge Voltage
You can choose from 11 stop-discharge voltage levels (2.5V to 3.5V).
- Chwazi kanal la vle.
- Enter the menu using the Menu /M Key.
- Navigate to the 'STOP' voltage anviwònman.
- Sèvi ak la Adjust /S Key to select the desired stop discharge voltage (2.5V, 2.6V, ..., 3.5V).
- Konfime anviwònman an epi sòti nan meni an.
5.5. Nòt Enpòtan sou Itilizasyon
- Discharge current is fixed at a maximum of approximately 1A (non-adjustable, non-constant current).
- Chaje voltage is fixed at 4.2V.
- This tester is pa konpatib with LiFePO4 batteries.
6. Enfòmasyon sou Sekirite
The device incorporates several safety features to ensure safe operation:
- Pwoteksyon Surchof: The integrated radiator fan (11) and internal sensors help prevent the device from overheating during operation.
- Otomatik Power-Off: Settings are automatically saved in case of power loss.
- Charge Cutoff: Automatic charge cutoff prevents overcharging of batteries.
- Sispann egzeyat: Configurable stop discharge voltage prevents over-discharging.
Always ensure correct battery polarity when inserting batteries to prevent damage to the device or batteries.
7. Antretyen
- Kenbe aparèy la pwòp epi san pousyè. Sèvi ak yon twal mou epi sèk pou netwaye.
- Avoid exposing the tester to moisture or extreme temperatures.
- Ensure the cooling fan (11) is not obstructed to maintain proper airflow.
- Sere aparèy la nan yon kote ki sèk, fre lè li pa itilize.
NAN. Depanaj
- Internal Resistance Readings Appear High at Low Voltages: If internal resistance readings seem unusually high, reinstall the battery. This can often provide a more accurate measurement.
- Aparèy pa limen: Ensure the Type-C power cable is securely connected to a functional 5V DC power source. Try a different cable or adapter if necessary.
- Battery Not Detected: Verify that the battery is correctly inserted with the correct polarity and that it is a compatible 18650 flat-top lithium battery.
