• When it shows “1-U”, Press the white button for 3s then you can adjust the voltage admeasuring apparatus. Press it for a longer time, the voltage goes up. Then Press it for another longer time, the voltage goes down. Do it again and again. To save and exit Automatically after the screen is twinkling.
• When it shows “2-b”, you can change the type of battery.
  • 12V: 1pc 12V Lead-acid battery
  • 3.7V: 1pc 3.7V Lithium polymer battery
  • 3.2V: 1pc 3.2V Lithium iron phosphate battery
  • 1.2V: 1pc 1.2V NiMH battery
• When it shows “3-c”, you can adjust the number of batteries.

Please refer to the following:

• 12V Lead-acid battery: 1-10pcs
• 3.7V Lithium polymer battery: 2-28pcs
• 3.2V Lithium iron phosphate battery: 3-32pcs
• 1.2V NiMH battery: 10-70pcs
• When it shows “4-d”, you can adjust the display mode. “V” is voltage mode. “%” is percentage mode. “V %” is voltage& percentage cycle mode.
• Note: This tester for Lithium and lead-acid batteries Universal, the factory default setting for 24V lead-acid battery power and voltage cycle display, If you need to test other specifications can be re-set by yourself.
