Additional Description


The MDMV is a small panel or printed circuit board mount digital voltmeter. With advantages of accuracy, size, and ease of installation, it is an ideal replacement for analog meters. The unit has a 3½-digit LCD display with 0.4' (10.2 mm) high digits. The display is positive image reflective (black digits, reflective background).

The integrated circuit is bonded directly to the printed circuit board and is mechanically protected. Internal electrical interface connections use elastomeric connectors to provide a corrosion resistant connection. This reliable construction also reduces the space requirements.

The MDMV module is designed to operate from a +5 VDC supply. The module measures input voltages from 0 to ±199.9 mV DC relative to the supply common.

Auto-zeroing is provided by the module, therefore no zero adjustment is required. If the input signal exceeds the input range, the unit display will indicate an overrange condition.

The module has three selectable decimal point positions and five selectable annunciators (BAT, V, A, m, µ). The BAT (Battery) annunciator is used to indicate a low battery condition, while the others are used to indicate Volts and Amperes.
