Specification:

Voltmeter Kit
Kit model: VOT-8
Operating voltage: 3.5V ~ 25V
PCB size: 33 x 52mm
Measuring range: 0V ~ 30V
Measurement accuracy: 0.1V

Feature:

The VOT-8 voltmeter kit is controlled by key-switch and can work well under the condition of two-wire or three-wire system
The two-wire ( by measuring voltage of the the VOT-8 power supply ), the measurement range of 3.5V to 25V
The three-wire ( by the external power supply voltage of 3.5V ~ 25V the VOT-8 power supply ), the measurement range 0V to 30V

Production steps:

Welding resistance
Welding capacitors, diodes, potentiometers
Welding of the key switch,Attention to the direction
Welding IC socket
Installing digital tube
Installation of single-chip and copper pillar (Note microcontroller direction)
Produced clip cord
Calibration voltage table:
Multimeter voltage profile, or a known voltage source voltage adjustment the VR1 potentiometer calibration

Principle of Operating:

The measured voltage is inputted via J1 PIN3. And it's inputted to the SCM PIN23 after the pressure resistance through R1, VR1 and R2. The analog voltage will be transferred to digital signal through the A/D converter inside of the SCM. At last, the measured voltage will be displayed on the digital tube after scanning the digital tube.
The system power is connected reversely through S1 polarity. And the IC of diode (from D1 to U2) outputs voltage 3.3V.
