A device that uses lights to monitor the working or positionstatus of circuits and electrical equipment. The indicatorlight is usually used to reflect the working state of thecircuit (powered or not), the working state of the electricalequipment (running, out of service or test) and the positionstate (closed or open).

The indicator light that reflects the working status of theequipment, usually a red light is on to indicate that it is inoperation, a green light is on to indicate that it is in a stateof shutdown, and a milky white light is on to indicate thatit is in a test state; the indicator that reflects the status ofthe equipment is usually lit to indicate that the device ischarged. Off means that the device is de-energized; theindicator light that reflects the working status of the circuit,usually a red light on means live, and a green light onmeans no electricity.

In order to avoid misjudgment, check the condition of thebulb or light-emitting diode frequently or regularly duringoperation.

 

1, Ultra-thin power display, 5 LED indicators, the displayis more intuitive and beautiful.

2. lt can be used in a wider range, lithium batteries, lead-acid batteries, lithium iron phosphate, electric vehiclebatteries and electric equipment can be used.

 

1.Connect the positive and negative terminals of thedisplay board to the positive and negative ends of thebattery under test, lightly press the red button with yourfinger, and the lED light will light up to display the real-time battery power.

2. Release your finger, the ED light will be off after a delayof 3-10 seconds, and it will not consume electricity whenit is static.

3.With reverse connection function, it will not burn even ifthe positive and negative connections are reversed, justadjust it.

 

(the following data is a reference value, there will be

a 2% error range, do not shoot if high accuracy isrequired)

Reminder: 3.7V lithium battery uses 1 red powerindicator, 4 green battery indicators (other voltageranges are 1 red power indicator, 4 blue batteryindicators)

(Note: N is the number of battery cells)The first power indicator is red

The battery voltage is greater than N×3.3V,the second blue light is on

The battery voltage is greater than N×3.5V,the third blue light is on

The battery voltage is greater than N×3.7V，the fourth blue light is on

The battery voltage is greater than N× 3.9V,the fifth blue light is on

12V lead-acid voltage range: (4 strings of lithiumiron phosphate batteries can be used)

The battery voltage is greater than 11.0V,the second blue light is on

The battery voltage is greater than 11.3V,and the third blue light is on

The battery voltage is greater than 11.6V,the fourth blue light is on

The battery voltage is greater than 12.9V,the fifth blue light is on
