The document introduces a 9 segment LCD color scale auto-zero 1V d.c. full scale reading meter, suitable for panel mounting, no calibration required, splashproof. This product features low cost and compact design, ideal for low or high volume applications. Other voltages and currents can be measured by adding 2 scaling resistors. The meter is suitable for applications where the order of magnitude of the reading is more important than the value of the reading itself, allowing the operator to quickly scan the display and receive visual feedback. Installation is very easy, requiring only a single round hole drilled in the panel.
The EMA 1710 9‑segment LCD meter provides a low‑cost, compact indication of a 1 V dc full‑scale reading. It is intended for applications where the order of magnitude of the measurement is more important than precise value, offering a quick visual cue for operators. The meter can be adapted to other voltage or current ranges by adding scaling resistors.
Installation is straightforward: a single round hole in the panel is required, with a rubber seal for splash‑proof protection. Wiring is done via three wires (V+, V‑, and Vin) and a screw‑stud, washer, and nut. The manual also includes safety notes to comply with the Low Voltage Directive and BS EN 61010.
