SENSOR PRODUCTS Preliminary APPLICATIONS Compassing Navigation Systems Hand Held Display Module HMD5000 Attitude Reference Magnetic Anomoly Detection Proximity Detection Laboratory Instrumentation Traffic and Vehicle Detection H and Held Display Module for digital magnetic sensor products. Displays heading, pitch and roll information when connected to the HMR3000 Digital Compass Module. If used with the HMR2300 Smart Digital Magnetometer, magnetic field readings in the X, Y and Z directions, as well as the magnitude of all three axes combined are shown. FEATURES AND BENEFITS Hand Held Portable, runs on batteries, easy to use in field applications Flexible Design Works with Honeywell's HMR3000 Digital Compass Module or Honeywell's HMR2300 Smart Digital Magnetometer GENERAL DESCRIPTION The HMD5000 is a small hand held unit with actual case dimensions of 3.60 x 5.70 x 2.09 inches. It weighs 0.54 pounds. The interface cable is 3 feet long and has a female 9-pin "D" connector. The accuracy and resolution of the HMD500 is dependent on the instrument with which it is used -- the HMR3000 Digital Compass Module or the HMR2300 Smart Digital Magnetometer.

Magnitude is calculated using the formula: X2 + Y2 + Z2. Figure 1 illustrates this output in both the "Gauss" and "Counts" mode. 2 , 0 3 4 Counts Mode Figure 1. Sample output when connected to an HMR2300 HMD3000 Heading - If the display is interfaced to an HMR3000 Digital Compass, the output consists of Heading, Pitch and Roll data with Status indicators for each reading if it is out of range.
