DMS-40PC Series, 4 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 +50°C operation.
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.
