    DMIs have been designed with features to provide you with a versatile and functional instrument that can be learned in a very short time. The RAC-200 contains all of the features of the RAC-100 with the addition of memory storage and data output. This allows for saving of information for later download to a computer or printer.

  • Page 7: How Do They Work

    Chapter 1 — Introduction How do they work? To use the RAC-100 or 200 DMI to accurately measure distance, either a modular distance sensor (MDS) or mechanical transmission interface 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-100 and 200 User’s Manual Quick Start Guide The RAC-100 and 200 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 instru- ment.

    Distance Sensor. If you are installing a different type of sensor, refer to the instructions that came with the sensor itself. The JAMAR RAC-100 and 200 distance measuring instruments (DMI) are very reliable instruments. However, there can be some external variables that could affect proper operation and the ability to accurately measure dis- tance traveled.

Route the red and black end of the 20’ grey VSS cable through the firewall. This can usually be done by using an exist- ing rubber grommet where other wires pass through the firewall.

    RAC-100 and 200 User’s Manual Automatic Calibration Procedure In order to accurately measure distance, your RAC-100/200 must know the exact distance that the vehicle will travel based on pulses from the vehicle's transmission. The calibration number is the automatic calculation that rep- resents the number of pulses received over a set distance.

The count you see represents the pulses seen from your transmission sensor and not the distance being traveled, so don't panic when the display doesn't equal the actual length of your course. Step 6 When you reach the end of the course, stop your vehicle so that you are exactly aligned with the end marker using the reference point on the vehicle used at the beginning of the course Press the...
