<Temperature Unit>
the temperature unit can be set to °C or °F. Note that this setting influences the
digital interfaces like RS485 for both object and head ambient temperature.
<Key Enter Lock>
the box has a user interface lockout feature that keeps the box from being
accidentally changed from the control panel (locked by default under
DataTemp Multidrop Software and Profinet communications). This lockout
mode denies access to the
button to avoid the saving of adjustable
parameters. The unit can be unlocked by pressing the
button and the
button simultaneously for 3 seconds or alternatively by pressing the
button
for 5 seconds.
<Display Backlight>
defines the switching behavior for the display:
<ON>: switches the backlight on
<OFF>: switches the backlight off
<60sec.OFF>: switches the backlight off after the giving time
To preserve the display’s longevity, the backlight should be turned off in case of
not using it!

Averaging
Averaging is used to smooth the output signal. The signal is smoothed depending on the defined time
basis. The output signal tracks the detector signal with significant time delay but noise and short
peaks are damped. Use a longer average time for more accurate damping behavior. The average time
is the amount of time the output signal needs to reach 90% magnitude of an object temperature jump.
Figure 35: Averaging
A low level input (GND) at external input FTC3 will promptly interrupt the averaging and will start
the calculation again.
