- Page 2 Another new feature of the DTM-152 is its data logging capability where user can now do their data gathering on the DTM itself and saves the output CSV file on to an external memory drive such as a USB drive or hard disk. This eliminates the need for a separate computer terminal and software to do a data log of a particular session such as field mapping of a magnet.

Page 6: Connecting The Hall Probe
Before handling the probe, please read the following: Group3 Hall probes are built to be as robust as possible for a small, precision device. However, it is most important that certain precautions be taken when handling and installing probes so that they are not damaged or destroyed, and to preserve their accurate calibration. -
Page 7: Installation Techniques For Electrically Noisy Environments
INSTALLATION TECHNIQUES FOR ELECTRICALLY NOISY ENVIRONMENTS The DTM-152 is a precision electronic measuring device. Because of the nature of the measurements it is asked to do, it is frequently exposed to conditions that are considerably worse than are normally encountered by precision instruments. Therefore, the teslameter has been carefully engineered to be as immune as possible to sparks and other forms of interference through the use of several kinds of power input filtering and a special high-isolation switchmode power module built into its circuitry. -

Range 3 3.0T 0.3T NETWORKING: USING DTM-152 LABVIEW VI Attach Ethernet connector RJ45 to the port found at the rear of unit marked to connect to the local network or router. Ethernet communication is automatically set to ON and DHCP when a network is detected using the Ethernet port. - Page 9 Once activated, user can access and control the DTM remotely using the Group3 DTM-152 LabView Virtual interface. See separate manual on “How to install DTM-152 LabView VI”. B. GRAPH The graph displays the reading in real time and can be configurable to auto scaling, unipolar or bipolar field. The graph window also shows if there is a current data log session as well as a counter for out of range readings (if on unipolar and bipolar).
- Page 10 User can also set an offset if user needs to add or subtract a field value to set as benchmark field. User can erase the offset that was added to return to the original field reading. Press OK to save and exit the configuration dialogue box or press Cancel to exit without saving the configured settings. GROUP3 TECHNOLOGY LIMITED WWW.GROUP3TECHNOLOGY.COM...
- Page 11 C. DATA LOG The DTM-152 has the capability to data log a field measurement session. This feature makes field measurement quite easy and eliminates the use of additional computer and specialized software to do the operation. All the user needs is a USB memory stick (at least 4 GB and max 256 GB) to save the file.
