- Page 2 The DME uses ultrasonic impulses to determine a distance. The speed for the ultrasonic signals to travel in the air depends on factors such as air humidity, air pressure and above all, the air temperature. The DME has a built-in temperature sensor that automatically will compensate divergences and give correct distance measures even if temperature changes.

Once you have set the prism factor, select DBH Measuring at [F2] by pressing the red button twice. When you take a reading the number displayed is the minimum diameter that a tree should have to be counted in the plot, a calculation based on the set prism factor and distance to plot center.

Questions and answers
my calibration function does not seem to be working
To fix the calibration function on your Haglof DME, follow these steps:
1. Measure Distance: Use a tape to measure a 10-meter distance between the transponder and the front of the instrument.
2. Enter Calibration Mode: Press the red button repeatedly until function F9 appears on the display.
3. Check the Display: The screen should show "10m" indicating calibration is ready.
4. Ensure Correct Interval: The instrument will approve calibration only if the measured interval is between 9.6 and 10.4 meters.
5. Temperature Adjustment: Allow the instrument enough time to adjust to the current temperature (function F7). If carried in a pocket, it may take up to 10 minutes for full adjustment.
6. Consider Temperature Error: The temperature-dependent error is approximately 2 cm per degree Celsius.
If calibration still fails, ensure the instrument is used in proper conditions and repeat the process.
