MeterMatch allows you to mix and match different gauges and senders, or to make gauges more accurate. It can be used with many gauges that have resistive senders - such as fuel, oil pressure and temperature gauges. In addition, it allows you to have low and/or high set-points that will trigger a bright, blinking, LED indicator to alert if the gauge exceeds normal values.
It is housed in a small (2.4" x 1.85" x .93") enclosure that can be located behind the dashboard near the gauge. Wire connections are made via a screw-terminal strip inside.
This MeterMatch video describes MeterMatch installation and use. While it contains a lot of detailed information, most of the information you will need for the typical installation and programming (calibration) is included in the first few minutes. If you would like to move around to see particular topics, here are the start times for the various sections: 0:00 Introduction/Overview, 1:51 Wiring, 3:19 Basic Calibration, 6:34 Calibration with known values, 10:46 Alarm LED, 14:45 Voltage Correction, 17:02 Reading Averaging, 18:38 Other Calibration Ideas. Note that all of the information included in the video is also in the instruction manual which may be used for reference to augment the video. The video is also available on YouTube, click here.
