The DPM 2000 is a 3½ digit LCD module that offers a combination of high performance, elegant appearance, and low cost. The module uses a bandgap reference for extra temperature stability. The DPM2000S is a single rail version with a built-in negative rail generator, allowing the meter to measure a signal referenced to its own power supply 0V.
The DPM 2000 LCD module offers a 3½‑digit display with a 15 mm digit height and programmable decimal points. It features a band‑gap reference for temperature stability and, in the single‑rail version, an internal negative rail generator.
The document details scaling resistor options, pin assignments, safety limits (max 60 V on pins), operating temperature range, and various operating modes. Special notes cover annunciator handling and on‑board link configuration for different measurement applications.
