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 optional DISPLAY HOLD function. Small size, low cost and adjustment-free reliability make the DMS-20PC Series the best choice for all your 3½ digit, LED, DPM applications.
