11.6.5 Lock Mode
The access to the unit is possible via serial interface (software) and
via the direct user input (mode buttons, LCD display). It is possible

11.6.6 Mode Setting for the Digital Input FTC3
The digital input FTC3 (see section 5.4.4
on page 28) can be used as follows:
XN=T
FTC3 as trigger
XN=H
FTC3 with hold function
11.6.7 Changing the Sensing Head Calibration Data
If it is necessary to exchange the sensing head, you must set the
calibration data for the new sensing head:
XZ=0123 4567 FFFF FFFF
according to the head calibration data
For MID/MIC‐models the last eight numbers are not used and must
be set to „F“ like shown in the example above. For MIH‐models and
specials (like MTB or G5) all sixteen numbers are used.
11.6.8 Ambient Background Temperature Compensation
In case of compensating the ambient background temperature, the
following modes are available:
AC=0
no compensation
AC=1
compensation with a constant temperature value set
with command A.
