Note:
The Minimum
Volumes are measured in the
standard measurement
required by each specific
report.
The number of digits allowed
for area to calculate volume is
limited to a 5 digit value for ft2
and a 4 digit value for m2.
Based on the minimum requirements displayed in Table 5-1, configure
the instrument as follows:
• Press MAIN to return to the MAIN screen.
• Press CONFIG to enter the Configuration screen.
• Press SAMPLE.
Note:
The Sample time
automatically changes to
31:42 (31 minutes, 42
seconds).
• Press the CYCLES button.
• Set the CYCLES value for 1 and press ENTER. Note that the
instrument beeps twice and clears the value. This is intentional as
the minimum cycles is 2 and changing to 1 will cause errors.
Entering more than 2 will work, though, if needed.
• Once the primary settings of Class and Area are entered, the values
are set for sample time/volume and cycles. Unless required by
SOP, there is no need to change these other values.
• Make sure to add the needed locations and press BACK.
Note:
This is all that is
needed to meet the minimum
requirements to classify the
report.
Increase any of the
configuration parameters in
order to meet additional
reporting needs.
• Press the MAIN button.
• Press START and allow the instrument to record the required
sample(s) at the first location.
Figure 5-81 Prompt to Change LOCation
• When it has finished, it will prompt to change to next location; a
YES response will change the Location but the user must press the
START button when set up and ready in the next Location.
• Move the instrument to the second location and press START.
