## Overview

The Murphy by Enovation Controls AT-30 Analog Tachometer is a robust, solid-state instrument designed for accurate engine RPM measurement. Compatible with 12 or 24 VDC systems, it features a large 240° dial sweep for easy reading, a single push-button for quick calibration, and an illuminated display for night use. Engineered for inductive ignition systems, it mounts easily into a standard 3-3/8 inch dash hole, making it a reliable upgrade for professional-grade vehicle monitoring.

## Description

The AT-30 tachometer is a rugged instrument with solid-state circuitry for indication of engine RPM. It is equipped with a ring nut for mounting into a standard 3-3/8 in. (86 mm) dash mounting hole. A full 240° sweep of the pointer gives an accurate indication on a large easy-to-read scale, and the dial can be illuminated for night reading. This AT Series tachometer indicates engine speed in revolutions per minute (RPM). Calibration has been improved and is now accomplished with a single push button on the back. Not intended for use with Capacitive Discharge (CD) ignitions or magnetos, only for inductive, automotive-type ignitions. The tachometer is for negative ground or isolated electrical systems. If the instrument is connected to reverse polarity, it will not operate until proper connections are made. It is powered by a 12- or 24-volt battery (operating range: 10-32 VDC). Replaces Murphy part numbers: ATS-30-12 (20700188), ATS-30-24 (20700202), ATS-40 (20700227), ATA-30-12 (20700175), ATA-30-24 (20700198), ATA-40 (20700134).
