Voltmeter Ammeter Description

| This Voltmeter Ammeter was designed to measure output voltage of 0-70V / 0-500V with 100mV resolution and 0-10A or more current with 10mA resolution. It is a perfect addition to any DIY laboratory power supply, battery chargers and other electronic projects where voltage and current consumption must be monitored. Thanks to added calibration via SETUP, UP & DOWN buttons it is now possible to calibrate the meter to measure voltage that is higher than 70V and current that is greater than 10A.
The heart of the Voltmeter Ammeter is PIC16F876A microcontroller with built-in analog to digital converters (ADC) and 2x16 green / blue backlighted LCD display.

Voltmeter Ammeter uses very few external components making it possible to fit this handy meter on a small PCB. The meter provides exeptionally accurate readings due to buit-in software based calibration and the use of 1% metal film resistors. It needs only one supply voltage that can be acquired directly from the main power supply. Entire
