16. charging stops when the charging current is less than 0.1A.
17. Save after powering off: Only the setting parameters are saved, not the measurement data.

Instructions for Use:

1. Turning the Product On/Off:
   The product has no power key, and will automatically turn on when the power is turned on and turn off when the power is turned off.
2. Language Switching:
   Press and hold the “Menu/M” button and then turn on. After the main interface is displayed on the screen, release the “Menu/M” button. Wait for 10 seconds, then turn off and restart the machine.
3. Switching channel display:
   Each channel is independent of the other and does not interfere with them. Click the “Channel/CHN” button to change the display channel, and you can view and set the parameters of each channel.
4. Internal resistance test:
   Install the battery, turn on the power, and wait for 10 seconds. The results of the battery voltage and internal resistance test are displayed. This product uses the DC two-wire method to test the internal resistance. Due to the limitations of the test principle, the battery may not be recognized, and the internal resistance remains unchanged. Display of the situation 9999.
   When the battery is not installed, the test circuit is open, which corresponds to infinite resistance. The internal resistance shows 9999 milliohms.
5. Charging function (not suitable for charging lithium iron phosphate batteries):
   Install the battery into the battery holder, adjust the mode to “Charging” mode, click “Start/Stop/R/S” to run the program; after charging is complete, the status indication is complete; the charging process records capacity, energy and charging time, and the charging capacity measurement is for reference only, please refer to the discharge capacity.
6. Test capacity:
   The capacity test requires discharge and waiting time. The capacity test is carried out through the discharge of the resistor. During discharge, the resistor heats up and generates a high temperature. Do not touch it directly with your hands to avoid burns. The capacity test result is only the capacity measured from the start of battery discharge to the trigger stop during the test phase.
7. Battery capacity distribution and run cycle:
   The capacity distribution run cycle is a process of charging, discharging, and charging. During use, the stop voltage should not be lower than 2.8V; otherwise, charging is not possible, and the program will not work normally.
