Vehicle Installed Distance Measuring Instruments

Accurate, reliable and easy to operate, the RAC Plus I and RAC Plus II units are THE BEST distance measuring instruments on the market. These cost-effective units save time and money by allowing personnel to measure distance, accurate to 1 foot per mile, while driving as fast or slow as necessary. They also incorporate our exclusive Modular Distance Sensor technology to provide you with the highest degree of accuracy.

Much safer than the old 'Hand-Wheel', these units will pay for themselves in increased productivity in a matter of days.

The RAC Plus series of DMIs replace the older RAC-100 and RAC-200 units, which were originally introduced in 1993 and quickly became an industry favorite. The RAC Plus series offers new features and improvements to the older RAC-100/200 units.

RAC Plus I and RAC Plus II - Shared Features

Shallow Case Design
Light weight, high-impact ABS plastic case (7.8"W x 2.3"H x1.2"D) allows you to mount the DMI to the front of the dash board or virtually anywhere inside the vehicle.
Dual LED Displays
Dual 6-digit LED Displays are easy to read at any angle both day & night. The dual displays separate distance data from speed, calibration number, vehicle number, time and menu selections.
Four Brightness Levels
Select the level best suited for ambient light conditions.
Menu Driven
Simplifies user selection for various operational capabilities.
Automatic Calibration
Allows quick, simple calibration on all vehicles. Stores four separate vehicle calibration numbers for multi-vehicle usage.
Extremely Accurate
Distance measurements accurate to 1 foot per mile, even in slow speeds.
Change Distance
Pre-Distance if starting at a known point, count up/down or add/subtract distance from current display.
Count & Display Hold
Freeze the display while continuing to accumulate distance with Display Hold or stop accumulation of distance with Count Hold.
Interval Distance
Display distance intervals between points of interest (i.e. Telephone Poles, Signs, Pavement, Markings, etc.)
Distance Conversion
With a simple push of the Unit key, convert distance from Feet to Miles to Kilometers.
Distance Pulse Output
Send calibrated distance pulses to a lap top computer or ancillary equipment. The interval and duration of the output signal are user selectable from key board.
Dependable
A power-on self test (POST) is performed each time the DMI is turned on. As part of the POST, the calibration number is displayed for your verification.

RAC Plus II - Additional Features

Memory
The RAC Plus II will allow you to store up to 3500 events in memory. Ideal for inventory applications, the Events are identified by using a four digit numeric code (0 thru 9999) to identify signs, guide rail, pavement marking, intersections, railroad crossings or other highway features. Events are stored in nonvolatile RAM (NVRAM). This NVRAM will hold your data for approximately 50 years, or until you clear the memory.
Data Output
Download the stored data to your PC or laptop. The downloaded data contains the memory location (0-3500), event code (0-9999),distance, interval distance, time and speed for each event.
Real-Time Output
If you prefer to use a laptop computer in the vehicle, the RAC Plus II will send distance data direct to the computer on a real-time basis. This provides virtually unlimited memory.
