Description

4 1/2 digit LCD, 20V

The DP-2000A Series is a highly accurate, high-resolution measurement device in a miniature panel meter package. This 4 1/2-digit LCD meter consumes very little power (about 15mW), and requires only 0.83" of space behind the panel. The combination of small size, low power, and high performance make this the meter of choice for a broad range of applications requiring portability and precision.

Three input voltage ranges are offered: ±200mV, ±2VDC, and ±20VDC. Automatic polarity, overrange indication, adjustable decimal point, and display HOLD are standard features.

The snap-in bezel packaging enables easy and rapid installation of the meter. A 13-pin connector is available as an option. Call to ask about backlit versions of this meter.
