Peacefair PZEM-010 Digital Battery Voltage & Internal Resistance Tester | LCD Meter for Lead Acid & Lithium

Product Description

Description:
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.
Function:
Measure the voltage and internal resistance of 18650 lithium battery and AA / AAA alkaline battery and display them through LCD.
Display Interface:
HTN wide viewing angle LCD: voltage + internal resistance + SOC + green backlight(seeFigure 2)
Display description:
1.VoltageMeasurement range: 0.5-9.99V (Forward); -0.5-(-9.9V)(Reverse)Accuracy: ??1%2.Internal ResistanceMeasurement range: 0-999m??Accuracy: ??1%3.SOCThe 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 lossWhen 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 (See Figure 3).5. BacklightDefault 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.SleepIn 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.
Button:
In normal display status: short press the button will turn on/off the backlight; In normal display status: long press the button for 3 seconds will turn off the backlight and display and enter the sleep mode;In sleep mode: short press the button will wake up the display, If display, LoH for 1 second and there is no other display, please charge in time.
Specification:
Specification of standby battery: 3.7V/1000mACharging time: 1.5hPower consumption: sleep mode: 3uA;Working status: backlight off: 22mA; Backlight on: 40mA;Working time of standby battery: backlight off: 45h; Backlight on: 25hCycle charging times of standby battery:> 1000 times
Note:
1.This product is not applicable to AA/ AAA carbon battery measurement;2.During measurement, if the voltage or internal resistance of the tested battery is 0, it maybe caused by poor contacting. Please reinstall the battery and measure again.3.This product is not waterproof.
Package included:
1 x Resistance Tester
