It is a Digital Meter/Battery Capacity Voltmeter Tester/Adjustable Digital Panel Meter, Voltage measuring range: DC6~120V (wide range),the maximum input voltage can not exceed 120V, Suitable for Lithium and lead-acid batteries, Applications: Various instruments and meters; portable device; power bank; medical device, electromobile, self-balance car or other products Voltage Capacity measurement.

• Suitable for battery pack based on lead-acid battery.
• The screen can display voltage, power, percentage of electricity at the same time.(note: these three can be switched by the key.)
• Can measure adjustable voltage range of 6-120V.( Lead-acid battery 12V for this item)
• Anti-water and easy to connect with only two wires.

• 1. Power on( red for + and black for - .
• 2. Press a few seconds to setting mode: from 1-U, 2-b, 3-C to 4-d.
• 1-U: adjust voltage
• 2-b: setting battery type
• 3-C: setting number of battery
• 4-d: setting "showing mode"
• 3. Adjust Voltage:
• While on 1-U, press the button to enter into adjusting voltage mode, release it and press again,  volatge will be step-up adjusted; release the button and then press it to step-down adjust; Repeatly adjust and save the setting while the screen flash and exist setting.
• 4. Adjust battery type:
• While on 2-b, press the button to change the type of battery press one by one will showed: 1.2V__2V__3.2V__3.7V__12V ( While adjust to appropriate battery type, release the button, save and  exist setting when the screen flashing.)
• 1.2V: NI-MH battery, each battery 1.2V
• 2 V:  Lead-acid battery, each battery 2V
• 3.2V: Lithium iron phosphate battery, each battery 3.2V
• 3.7V: Polymer battery,each battery 3.7V
• 12 V: Lead-acid battery, each battery 12V
• 5. Setting number of batteries:
• ◆ While on the "3-C" setting, press the button to enter into setting number of batteries.
• ◆ Release the button and press again,value will be step-up adjusted; release the button and then press
• it to step-down adjust; Repeatly adjust to appropriate number of batteries.
• ◆ Save the setting while the screen flash and exist setting.
• ◆ Different range for different type batteries:
• 12V Lead-acid battery: 1-10 sections
• 3.7V Lithium battery: 2-28 sections
• 3.2V Lithium ion battery: 2-32 sections

• 1.2V NI-MH battery: 10-70 sections
• 6. Setting showing mode:
• ◆ While on "4-d", press the button to enter into setting showing mode.
• ◆ Release the button, press it once showed one mode: V - voltage, % - percentage of power( these two
• will be in cyclic display)
• ◆ Adjust to appropriate mode,save the setting while the screen flash and exist setting.
