Description:

This table has fast reaction speed and high precision;

Clear display, intuitive reading and good stability;

The circuit design is advanced and reasonable, with strong anti-interference ability, which can effectively suppress high-frequency interference;

The kit features good materials, good workmanship, beautiful appearance, long service life, convenient installation and use, etc.

Voltmeter suitable for DIY enthusiasts to weld and assemble.

Parameter introduction:

Working voltage: DC5V

Working current: 35mA

Measurement accuracy: it can be calibrated to obtain high accuracy, and there is no parameter temporarily.

Measuring range: divided into three grades:

Measure small voltage at 0-2V gear

Measure medium and low voltage at 0-20V gear

0-200V gear, measure higher voltage.

PCB size: 70.6 * 39mm

Opening size for meter head installation: 77 * 40mm

Display window size: 51 * 24mm

Display color: red

Tools required for production (not included): multimeter, electric soldering iron, nozzle pliers

Range selection method: there are solder joints for gear selection on the board,

When two points of 0-2V gear are welded together and RX welding resistance is 1K, the measurement range is 0-2V;

When two points of 0-20V gear are welded together and RX welding resistance is 100K, the measurement range is 0-20V;

When the two points of 0-200V gear are welded together and the RX welding resistance is 1M, the measurement range is 0-200V;

Over range display: 1 or - 1 in the first place

In the kit, there are two types of RX: 100K and 1M, and welding can be selected according to your own measuring range.

This voltmeter can also be changed into an ammeter.

The method to change the ammeter is to reserve a 2W

0.1 ohm high-precision resistance welding position on the board, weld this resistance, and then RX does not need to be welded. This is a 0-2A ammeter.

The function of the measurement and calibration potentiometer: input a voltage, and then adjust the potentiometer. The value displayed on the meter head is the same as the measured value of the multimeter.
