The digital voltmeter-ammeter is designed to measure the DC voltage and current of the connected power source. The module can be used in power supplies that require visualization of output parameters. It can also be used to measure voltage and current readings within a circuit of devices.

The module consists of two seven-segment red indicators. The voltage measurement range is from 0 to 99.9 V, and the current is from 0 to 9.99 A. The accuracy of the device readings is ± 1%. The measurement update rate is about 200 ms/time. This voltmeter-ammeter features a built-in shunt, which eliminates the need for an external shunt to measure current.

The meter board has 5 pins:
red wire: external device current measurement 0 - 9.99 A
black wire: "ground"
yellow thin wire: external device voltage measurement 0-100 V
red thin wire: power supply of the device with a voltage of 4.5 - 30 V
black thin wire: "ground"

There are two ways to connect a digital voltmeter-ammeter:
If the voltage of the measured power source is in the range from 4.5 to 30 V and has a common wire with the meter, then the device can be connected to its power supply.
If the voltage of the measured source is higher than 30 V, it is necessary to use an external power supply with a voltage of 4.5 to 30 V to power the device.
This meter is sold already calibrated. If necessary, calibrate the device, you need to use two tuning resistors. Using the I_ADJ potentiometer, the accuracy of the current measurement is adjusted, and the variable resistor V_ADJ changes the accuracy of the DC voltage.
