Alternate Source for DP-650

Series, 3½ Digit, LCD Display

Digital Panel Voltmeters

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 +60°C)

• Rugged, epoxy-encapsulated

plastic packages

• Large (0.4"/10.2mm) LCD displays

• Made in the USA!

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 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!
