| (R) (R) DMS-3019X Series Actual Size Alternate Source for DP-650 Series, 31/2 Digit, LCD Display Digital Panel Voltmeters DATEL's new DMS-3019X Series, 31/2 Digit, LCD Display, Digital Panel Voltmeters provide DP-650 users with a superior-quality alternate source. The DMS-3019X Series input/output connector is pin-compatible with nearly all DP-650 applications. Only minor sheet-metal modifications are needed to attain all the advantages offered by the DMS-3019X Series digital voltmeters. Three differential, high-impedance, input voltage ranges are available: 200mV (DMS-30193), 2V (DMS-30194) and 20V (DMS-30195). Provisions are also included for the addition of custom input-scaling resistors-- a feature found only on DMS-3019X meters. Autozero calibration, autopolarity changeover and a factorycalibrated ultra-stable reference circuit are standard. A reliable, epoxy-encapsulated DMS-30LCD digital voltmeter, with large (0.4"/10.2mm) LCD digits, is used in all three models. All internal and external connections are 100% soldered-- no elastomeric connectors are used. The DMS-3019X Series offers many noteworthy improvements over its competitors: wider operating temperature range, lower power consumption and higher input impedance, to name a few. And, most importantly, all DATEL digital panel meters are designed and manufactured in the USA! Features * Replaces DP-650, DP-652 and DP-654 meters * Connects directly to existing wiring * Available in three input ranges: 200mV, 2V and 20V * Low power consumption * Wider operating temperature range (0 to +60C) * Rugged, epoxy-encapsulated plastic packages * Large (0.4"/10.2mm) LCD displays * Made in the USA! +5V V+ 1 V+ R4 R3 V- +2.0V 3 DP COM 0 Vdc A/D CONVERTER DATA DP 3 4 1.23V REF.
