The DP-650 Series is an ultra-compact, low-power LCD meter requiring only 15mW of

power. This meter is ideal for applications requiring a highly reliable LCD display in a

small package. The snap-in bezel packaging enables easy and rapid installation of the

meter. The simplicity of design, overvoltage protection, and low power consumption all

contribute to the high reliability of this device.

Three input voltage ranges are available: ±200mV, ±2VDC, and ±20VDC. A 4-20mA

current input adapter (DP-670) is also offered. Automatic polarity, overrange indication,

adjustable decimal point, and display HOLD are standard features. The DP-650 Series

employs a dual slope integrating A/D converter, and operates from an internal 100mV

reference via a precision DC-to-DC converter. Typical accuracy is ±0.1%.

1. The connection shown utilizes differential inputs. For single-ended operation, INPUT(-) is

2. Display holds reading when HOLD is high (+5V). Readings are updated when HOLD is low

3. The decimal point is user selectable by connecting the decimal point pins (4, 5, or 6) to DP

4. Full-scale input span is adjusted prior to shipment. Further calibration is possible by adjusting

5. Unused pins should be left open.
