DATEL's new DMS-3019X Series, 3½ Digit, LCD Display, Digital Panel Voltmeters
pro vide 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 a vailable: ±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 changeo ver and a factory-
calibrated 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 competi-
tors: 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!
