APPLICATIONS
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
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
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.
Input Power Requirements
Supply Voltage 6-15 Vdc Unregulated
Power 72 mA @ 9 Vdc (300mA at Power Up)

When outputting data the LCD display
is divided into four quadrants. Each
quadrant being 8 segments wide.
When connected to the HMR2300
Smart Digital Magnetometer the
display outputs magnetic field strength
data in the X, Y and Z axes along with
Magnitude. Magnitude is calculated
using the formula: √ X2 + Y2 + Z2.
Figure 1 illustrates this output in both
the “Gauss” and “Counts” mode.
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. Figure 2
shows the compass output in both
Degree and Mils mode.
