  • Page 7: How Do They Work

    Chapter 1 — Introduction How do they work? To use the RAC Plus I or Plus II DMI to accurately measure distance, either a modular distance sensor (MDS) or mechanical transmission sensor is used to send pulses to the DMI. The Quick-Kit, which is a modified version of the MDS, can also be used.

  • Page 8: Quick Start Guide

    RAC Plus User’s Manual Quick Start Guide The RAC Plus I and II DMIs will allow you to accurately measure distance quickly and easily. However, before you can do this a few basic steps must be taken to ensure that you get the optimum performance from your in- strument.

    RAC Plus User’s Manual Before You Begin Note: The following instructions are for installing a RAC with a Modular Distance Sensor. If you are installing a different type of sensor, refer to the instructions that came with the sensor itself. The JAMAR RAC Plus I and Plus II distance measuring instruments (DMI) are very reliable instruments.

  • Page 11: Installing The Modular Distance Sensor

    Chapter 2 — Installation Installing the Modular Distance Sensor Most vehicles (1992 and newer) have an electronic speed output rather than a mechanical speedometer cable coming from the transmission. With these vehicles you will need to install either a Modular Distance Sensor (MDS) Vehicle Kit or a Modular Distance Sensor Quick Kit.

If you cannot locate an existing hole, CAREFULLY drill a small hole large enough for both the VSS cable and the +12Volt/Ground wires. EXTREME CAUTION must be taken to insure you do not drill into anything mounted on the opposite side of the firewall or cut any existing wiring.
  • Page 13 Chapter 2 — Installation is switched off with the ignition key. We also recommend the circuit should have as few devices as possible to avoid voltage fluctuations from Turn Signals, Brake Lights, etc. Plug the power cable Fig. 2.4 –Power Plug-in into the hole labeled Power on the MDS, as shown in Figure 2.4.

    RAC Plus User’s Manual Automatic Calibration Procedure In order to accurately measure distance, your RAC Plus must know the exact distance that the vehicle will travel based on pulses from the vehicle's speed sensor. The calibration number is the automatic calculation that represents the number of pulses received over a set distance.

  • Page 20 RAC Plus User’s Manual Step 7 Press Enter and the unit of measurement will return to your desired unit of feet, mile or meter. Press Enter again to exit the menu function and return to normal operation. Your calibration number for the vehicle selected is now stored in the RAC's nonvolatile (permanent) memory.

    Chapter 3 — Calibration If Your RAC Fails to Calibrate If your RAC fails to count during calibration, perform the following op- erational checks: Step 1 Locate the Sensor Test button on the front upper right of the MDS, shown in Figure 3.5.
  • Page 22 RAC Plus User’s Manual Step 2 The Tap Test will determine if the dis- tance pulses being sent from the MDS are getting to, and being processed by, the RAC. The Tap Test is performed using the rotary switch shown in figure 3.6.

    Manual Calibration Procedure It is very common to share one RAC on a plug-in basis between a number of different vehicles that have been equipped to accept the instrument. Installing additional vehicle kits on other vehicles is an inexpensive and cost effective means to greatly expand your measuring capabilities.
