AVT2004 B

Milivoltmeter with LED display is designed for a modular measurement set. The size and shape and, above all, the parameters make it suitable for incorporation in other devices, wherever there is a need for a digital, accurate voltage reading.
The kit uses the popular, ICL7107 integrated AC converter. The system directly controls seven-segment LED displays. They allow reading the measured value in the form of 3.5 digits. The polarization mark is also presented.
In the basic version, the module can work as a voltmeter with the range of 200 mV or 2 V.

The device is particularly recommended for designers of measuring equipment, wherever the measurement result must be clearly visible and in electronic laboratories

Selected voltmeter parameters:

• measuring range - 200 mV or 2 V
• input resistance> 10 Mom
• accuracy of the result - +/- 1 in the last position
• reading field - 3.5 digits
• signaling of exceeding the measuring range
• measuring cycle - approx. 0.3 s
• power supply - 5 V
• in the set a printed circuit board, a set of elements and documentation
