Programming Guide

XF

factory default values will be set

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 to lock the buttons. This allows access the unit only via software.

J=L

direct user input via mode buttons denied

Alternatively the unit can be unlocked by pressing the <Mode/Up> buttons simultaneously for three seconds.

11.6.6 Mode Setting for the Digital Input FTC3

The digital input FTC3 (see section 5.4.4 Trigger and Hold Function 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.
