Instructions for use:
1.Product switch on and off:
The product has no switch key, power on automatically turn on, power off shutdown
2.Language switching:
Live in the “menu / M” key and then power on, the screen displays the main interface, release the “menu / M” key, wait 10 seconds to restart after the shutdown can be
3. Switch channel display:
Each channel is independent of each other, do not interfere with each other, click the “channel / CHN” button to switch the display channel, and can view the parameters of each channel, and set the parameters of each channel
4.Test internal resistance:
Install the battery, power on, wait for 10 seconds, display the battery voltage and internal resistance test results, this product uses DC two-wire method to test internal resistance, subject to the limitations of the test principle, may not be able to identify the battery, the internal resistance is always displayed in the case of 9999.
When the battery is not installed, the test circuit is disconnected, which is equivalent to the infinite resistance value, and the internal resistance shows 9999 milliohms.
5. Charging function (not suitable for lithium iron phosphate battery charging):
Install the battery in the battery holder, adjust the mode to “charging” mode, click “start/stop/R/S” to run the program; after the charging is finished, the status indication is complete; the charging process records the capacity, energy, charging time, charging metering capacity is for reference only, please take the discharging capacity as the standard
6. Test capacity:
Capacity test needs to be discharged, need to wait for time, capacity test is carried out through the resistance discharge, discharge resistance heat generated high temperature, do not touch directly with your hands to avoid burns outside. Capacity test results are only the capacity measured during the test phase when the battery starts discharging and stops triggering.
7. Battery capacity dividing and running cycle:
Capacity dividing and running cycle is a process of charging, discharging and recharging, the stopping voltage can not be lower than 2.8V, otherwise it can not be charged and the program can not run normally.
8. Data zeroing:
Shutdown, switch mode, capacity, energy, time data is automatically cleared to zero

Package include:
