Description

DMS-40PC Series, 41/2 Digit, LED Display, Miniature DPM's are fully self-contained,component-like, plug-in meters that provide scientific-grade accuracy (typically ±2 counts or ±0.005% of full scale) and outstanding reliability at a very affordable price.

Within its miniature (2.17" x 0.92" x 0.56"), epoxy-encapsulated package, each meter contains a precision reference circuit; a high-resolution, autozeroing, factory- calibrated A/D converter; and a large (0.52"/13.2mm), easy-to-read, LED display. LED's are available in red, yellow and green colors.  Red LED's are also offered in high-intensity or low-power versions.

The versatile design of the DMS-40PC Series assures trouble-free installation and long-term operation.  Differential input voltage ranges include ±2V, ±20V and ±200V. Input impedance is a minimum 800k?.  Non-inverting inputs are overvoltage protected to ±250V, and CMRR is typically 86dB (dc to 60Hz).

The DMS-40PC's epoxy-encapsulated package has an integral bezel and color filter.  The moisture and vibration-proof package is extremely rugged and well suited for harsh environments and extended temperatures.  Devices are fully specified for 0 to +50operation.

All models operate from a single +5V supply and typically consume 500mW.  Low-power models, whose display is just as bright as standard models, typically consume 175mW.  DISPLAY TEST and HOLD functions are standard on each meter, and a complete set of BCD outputs are optional for sending data to CPU's or remote displays.
