Operating Modes 71
7.6 Thermo Scan
This operating mode is only usable if the optional device FS-Thermoscan is connected. The FS-
Thermoscan enables users to conduct a thermal mapping of what is in the ground or what may be
behind walls. The “Thermo Graph” and “Thermo Scan” functions of the eXp 4500 can help to locate
hidden items inside of walls or cave openings.
In operating mode Thermo Scan you have the possibility to create a graphical representation of the
distribution of temperatures. Also this operating mode is only available when the FS-Thermoscan is
connected to the eXp 4500. The scanning of the measured area is generally similar to the operating
mode “Ground Scan” (see section Ground Scan on page 51), with the only difference that instead of an
antenna the FS-Thermoscan is connected to the device. As soon as you confirmed the operating mode
and adjusted all necessary parameters, you will be asked if you like to do a calibration. If you confirm
this question with “Yes” you will first enter into the “Thermo Graph” operating mode to calibrate the FS-
Thermoscan. After you finished the calibration of the device, depress the multi-function control knob.
Now you have to start to scan the field. Therefore you have two possibilities:
•
Scan the area as usual
In this method the FS-Thermoscan has to be used like a conventional antenna. Hold the FS-
Thermoscan in your hand and point the Temperature Sensor towards the surface of the ground.
According to your adjustments of the scan mode move the device over the area while walking
next to it, in the Parallel or Zig-Zag mode.
•
Scan an area from the distance
Stand in front of the area you like to inspect, hold the FS-Thermoscan in your hand and point the
Temperature Sensor to the start point of your field. Now you can scan the area by moving the
Temperature Sensor continuously over the measure field. You don’t have to stand directly over
the measure point, it is enough if you orientate the FS-Thermoscan with the Temperature Sensor
