Product Type：Battery Internal Resistance Meter

Product Model：PZEM-010

Product Function：

This tester use four wire principle to test battery voltage and internal resistance with high precision, and is powered by built-in rechargeable standby battery; The innovative built-in four wire battery measurement cabin structure, high integration, small volume and convenient carrying. It is suitable for mobile battery detection.

Measure the voltage and internal resistance of 18650 lithium battery and AA / AAA alkaline battery and display them through LCD.

Measurement range：

1. Voltage

Measurement range: 0.5-9.99V (Forward); -0.5-（-9.9V）(Reverse)

Accuracy: ±1%

2. Internal Resistance

Measurement range: 0-999mΩ

Accuracy: ±1%

3. SOC

The SOC symbol is composed by battery frame + three battery cell indications, it is used to display the SOC of the standby battery; When the standby battery is blank, the battery frame will flash to indicate that it is time to charge; When charging, the battery cell will flash in turn to indicate that it is charging

4. Power loss

When you short press the button, if the LCD screen displays "Lo" for 1 second and there is no other display, it means the built-in lithium battery has lost power and needs to be charged in time, otherwise it cannot be used normally.

5. Backlight

Default status: the backlight is off, it can be turned on/off through the button When the battery is blank or in power loss status: the backlight will automatically turn off and cannot be turned on.

6. Sleep

In non charging status: if there is no operation on the button or no testing action within 30 seconds, the LCD and backlight will automatically turn off and enter the sleep mode.
