The OPERATE Menu
The DOWN arrow can be used to set the Operation Mode from ON to OFF. This will stop the measurement cycle, but
will not power-down the APDA-371. NOTE: If the operator sets the Operation Mode to OFF, or the unit stops itself
due to an error, it will still automatically set the mode back to ON at the top of the hour, and try to run a new
cycle! The only ways to prevent the unit from automatically starting a cycle are to power off the unit, leave the unit in a
TEST or SETUP menu, or leave the pinch rollers latched in the UP position.
The OPERATE menu has three soft-key options for viewing the operating status and sensor measurements while the
unit is operating: NORMAL, INST, and AVERAGE.
3.11 The NORMAL Screen
Normal Mode is the primary operation screen which displays most of the important parameters of the sample progress
in one place, as shown below. Many operators leave their APDA-371 in the NORMAL screen whenever the unit is
operating, instead of the Main menu.

The NORMAL Menu
The LAST C value indicates the last concentration record, updated at the end of the cycle. The LAST m value indicates
the last measured value of the reference span membrane. The value should be very close or equal to the expected
value (ABS). The other values are instantaneous measurements.
3.12 The INSTANTANEOUS Screen
The INST (Instantaneous) screen displays the instantaneous data values that are being measured by the APDA-371.
This screen is useful for monitoring the current reading of any optional sensors that may be connected to the APDA-
371. All values except Conc (concentration) and Qtot (total flow volume) are current. The Conc represents the
concentration of the last period. Qtot represents total flow volume during the last period.
