2-4 STARTING TO MEASURE
•
Start the EZMag3D software.
The first time you run EZMag3D, it will open the Connection Screen.
•
Plug in the THM1176 or TFM1186.
The magnetometer will take approximately 10 seconds to boot and should
then appear on the Connection Screen, allowing you to connect to the
instrument.
•
Place the probe in the magnet. On the THM1176-MF and THM1176-HF,
you can remove the probe cap to access narrow gaps
– see Chapter 3-
Overview. See the EZMag3D Manual for details on using the software.
•
(
Does not apply to TFM1186
– see Section 2-6!
) Check the offset before
each series of measurements by placing the probe in the Zero Gauss
Chamber. If the offset is higher than desired, leave the probe in the Zero
Gauss Chamber and perform the User Offset Correction procedure.
2-5 USING THE HANDHELD KIT
The ruggedized Windows tablet included in the Handheld Kit is like any other
Windows computer; all the procedures in the previous sections apply. Here are
some additional hints:
•
Use the adapter included to plug the THM1176/TFM
1186 into the tablet’s
Mini-USB connector.
•
The Mini-USB connector is also used to recharge the tablet, so the tablet
cannot be recharged while measuring. However, a fully charged tablet
should provide roughly four hours of operation, making for a compact and
lightweight handheld solution.
•
The hand strap on the back of the tablet is very practical, but it is
unfortunately made for using the tablet in portrait mode, which is not the
optimal orientation for EZMag3D.
•
The pistol grip, on the other hand, places the tablet in landscape mode,
and also dramatically extends the battery life, to more than a day. In fact,
by plugging the power supply into the pistol grip rather than the tablet itself,
you can recharge while measuring. However, note the precautions below.
