When the battery is not installed, the test circuit is disconnected, which means the resistance value is infinite, and the internal resistance shows 9999 mOhm.

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 programme; after charging, 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 by 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.

Separate the capacity to run the cycle is a process of charging, discharging and recharging, the use of the stopping voltage can not be lower than 2.8V, otherwise it can not be charged, the programme can not run properly

8.Data zeroing:

Switch off the machine, switch mode, capacity, energy, time data is automatically cleared to zero
