3-7 HOST COMPUTER AND SOFTWARE
The THM1176 family of magnetometers requires a host computer for power and
control. With the Handheld Kit, this host computer is a ruggedized Windows tablet;
otherwise, it is your computer. The probes supplied with the Desktop and
Handheld Kits are identical; in other words, you can also plug a probe from a
Handheld Kit into your computer.
The THM1176/TFM1186 are supplied with software, called EZMag3D. See the
included electronic manual for how to use this software. You can also integrate
this software into a larger measurement system, or even write software from
scratch; please see Chapter 4-Options for Computer Control for your different
options.
3-8 CALIBRATION, MAINTENANCE, REPAIR AND WARRENTY
•
Calibration procedure:
The THM1176 family of instruments can only be calibrated by Metrolab.
This is because special magnets, tooling and software are required to
calibrate all three axes, at multiple fields and temperatures, and write the
results to flash memory.
•
Recommended calibration interval:
You are of course free to fix the interval at which you send your instrument
back for calibration, within the context of your quality assurance policy.
Metrolab’s recommendation is to send the instrument back for calibration at
least once every eighteen months.
•
Recommended calibration dates:
To minimize costs, Metrolab establishes a limited number of dates in the
year when batches of THM1176 family magnetometers will be calibrated.
To avoid substantial extra charges, you should ship the unit back to
Metrolab in order to coincide with one of these dates. Please see Section
6-9 for a list of these dates.
•
Upgrades:
Via its website, Metrolab makes available improvements and bug fixes for
the THM1176 firmware, software and manual. The Download page of the
