The “UP” and “DOWN” buttons are used for setting the digital
display to the desired value, and the “ENTER” button is used for
saving a value previously set on the digital display. These buttons
are used when programming: the set points and other optional
settings and during calibration of the detector.

The rotary selector switch (labeled “MENU SELECT” on the panel-
mounted circuit board) is used for performing functions such as:
•
Setting the information displayed on the front panel
•
Programming set points
•
Displaying system information
•
Calibrating the detector
When the detector is in operation, this switch is typically set to
position “0” to continuously display the ammonia concentration.
