DMS-3019X Series
Actual Size
Alternate Source for DP-650 Series, 3½ Digit, LCD Display Digital Panel Voltmeters
DATEL's new DMS-3019X Series, 3½ 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!
