1. પાવર કનેક્શન: Connect the tester to a 5V DC power source using one of the two Type-C interfaces. An adapter and cable are typically included.
2. બેટરી દાખલ: 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.
3. સ્થિરીકરણ: 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. ઓપરેટિંગ સૂચનાઓ

The tester allows for independent operation of its four channels.

આકૃતિ 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

• નો ઉપયોગ કરો Channel /CHN Key (16) to switch between the four independent channels (CHN 1 to CHN 4).
• આ Menu /M Key (13) is used to enter or exit menu settings.
• આ Adjust /S Key (14) is used to change values or select options within a menu.
• આ 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).

1. Select the desired channel using the Channel /CHN Key.
2. દબાવો Menu /M Key મોડ પસંદગી દાખલ કરવા માટે.
3. નો ઉપયોગ કરો Adjust /S Key to select 'AUTO' mode.
4. Adjust the number of cycles (LOOP: 1-9) using the Adjust /S Key જો જરૂરી હોય તો.
5. દબાવો 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).

1. ઇચ્છિત ચેનલ પસંદ કરો.
2. Enter the menu using the Menu /M Key.
3. Navigate to the 'STOP' voltage સેટિંગ.
4. નો ઉપયોગ કરો Adjust /S Key to select the desired stop discharge voltage (2.5V, 2.6V, ..., 3.5V).
5. સેટિંગની પુષ્ટિ કરો અને મેનૂમાંથી બહાર નીકળો.

૬.૩. મહત્વપૂર્ણ ઉપયોગ નોંધો

• Discharge current is fixed at a maximum of approximately 1A (non-adjustable, non-constant current).
• ચાર્જિંગ વોલ્યુમtage is fixed at 4.2V.
• This tester is સુસંગત નથી with LiFePO4 batteries.

6. સલામતી માહિતી

The device incorporates several safety features to ensure safe operation:

• ઓવરહિટીંગ પ્રોટેક્શન: The integrated radiator fan (11) and internal sensors help prevent the device from overheating during operation.
• સ્વચાલિત પાવર-ઑફ: Settings are automatically saved in case of power loss.
• Charge Cutoff: Automatic charge cutoff prevents overcharging of batteries.
• ડિસ્ચાર્જ સ્ટોપ: Configurable stop discharge voltage prevents over-discharging.

Always ensure correct battery polarity when inserting batteries to prevent damage to the device or batteries.

7. જાળવણી

• ઉપકરણને સ્વચ્છ અને ધૂળથી મુક્ત રાખો. સફાઈ માટે નરમ, સૂકા કપડાનો ઉપયોગ કરો.
• Avoid exposing the tester to moisture or extreme temperatures.
• Ensure the cooling fan (11) is not obstructed to maintain proper airflow.
• જ્યારે ઉપયોગમાં ન હોય ત્યારે ઉપકરણને સૂકી, ઠંડી જગ્યાએ સંગ્રહિત કરો.

8. મુશ્કેલીનિવારણ

• 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.
• ઉપકરણ ચાલુ નથી: 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.

9. સ્પષ્ટીકરણો
