and gre FEATURES DMS-20PC Series, 3½ Digit, LED Display, Digital Panel Voltmeters combine a precision A/D converter; a factory-trimmed, highly stable, voltage reference; and a large
(0.37"/9.4mm), easy-to-read LED display in a single package that is only slightly larger
than the display itself. Displays are offered in either red, orange, amber, yellow, green or
blue colors. High-intensity and low-power (35mW total) red LEDs are also optional.
These low-cost meters are fully self-contained and fully functional. Their subminiature
(1.38" x 0.88" x 0.48"), epoxy-encapsulated cases incorporate built-in color filters and
bezels; are moisture and vibration proof; and function well in the harshest environments.
Their 12-pin, dual-in-line configuration offers component-like, plug-in convenience and
maximum versatility. Operating temperature range is 0 to +60°C.
The meters come with one of four, differential, input voltage ranges: ±200mV, ±2V
±20V or ±200V. Input impedance is a minimum 800kΩ. CMRR is typically 86dB (dc to
60Hz), and CMV is ±2V. Input overvoltage protection (on the non-inverting input) is ±250V.
Devices are fully calibrated at the factory to an accuracy of ±1 count (±0.05% of full scale
range) and never require calibration or adjustment.
A DISPLAY ENABLE function permits the display to be disabled for "power-down"
operation. All models have a DISPLAY TEST function. Standard red LED models offer an …
