7 Operation
Once you have the sensor positioned and connected properly, the system is ready for continuous
operation.
The operation of the sensor can be done by means of the built-in control panel in the sensor’s housing
or by means of the software that came with your sensor.
7.1 Control Panel
The sensor is equipped with a control panel in the sensor’s housing, which has setting/controlling
buttons and an LCD display. The panel is used primarily for setting up the instrument and is sealed
during operation. The buttons and the display are defined in the following sections.
Figure 12: Control Panel
The sensor has a user interface lockout feature that keeps the unit from being accidentally changed from
the control panel (locked by default in multidrop mode). This lockout mode denies access to all the
adjustable parameters on the control panel. Access to the display modes of the panel while in a locked
condition is provided.
7.2 Operation Modes
When you first turn the unit on, the display shows the current temperature. Pushing the keys of the
control panel will change the figures on the display as shown in the menu tree below.
