Simply apply power to the two rear terminals and the unit is operational. No additional components are required! The large, 0.37"/9.4mm, LCD display, with built-in "VDC" annunciator, can be easily read from 10 feet. Two models are available: one for 12Vdc nominal operation (+6.50-18.00V range, 0.01V resolution), the other for 24Vdc nominal operation (+8.0-50.0V range, 0.1V resolution). Reverse polarity protection is standard on both models. The DMS-20LCD-DCM utilizes a precision analog-todigital converter and ultra-stable passive components to achieve excellent performance over the operating temperature range of 0 to +60C. A rugged, ABS plastic package provides excellent protection against shock and vibration. DMS-20LCD-DCM's are without a doubt the most costeffective, LCD-display, digital voltmeters available anywhere, at any price.
