SPECIAL NOTICE FOR THE THM1176-HF and THM1176-HFC
Remember that the THM1176-HF is only calibrated to 14.1 T (formerly 3 T),
and the THM1176-HFC only to 1.5 T. Consequently, the 20 T range on these
instruments is only calibrated up to these limits. You should try to use the
lower ranges whenever possible; the best is to leave the instrument in auto-
ranging mode (the default).
SPECIAL NOTICE FOR THE THM1176-HFC
The probe is fragile. Be very careful when handling; even the weight of the
instrument cable is sufficient to damage the probe. Damage to either the
sensor package or signal cable will destroy the sensor. We strongly suggest
storing the probe in its protective case when not in use.
The sensor is sensitive to Electrostatic Discharge (ESD). Be sure to ground
yourself and follow proper procedure when handling the sensor.
SPECIAL NOTICE FOR THE TFM1186
Do not use the zero-offset correction feature with the TFM1186. In fact, the
fluxgate sensor is so sensitive that most zero-gauss chambers are completely
inadequate, and the zero-offset procedure will introduce a large offset error. If
the zero-offset procedure is nonetheless executed, you can restore the factory
offset as described in the EZMag3D manual.
