b. In the Enter Level fields, enter the value of Flow (Q),
Velocity (V), and Depth (D) that will trigger the Burst
Sampling rate.
c. Enter the Exit Levels in the exit fields. When Q,V, or D
drops below its Exit value, the ADFM will switch back
to the normal operating sample interval, conserving
battery power and data storage space.
14. Under Included Data Types, select all boxes. Select the
appropriate output (Serial, unless a modem is used).
15. To activate recording and storage of flow information,
check the Record Internally box, and select Slate or Wrap
mode.
In Slate mode, the recorder will stop recording when full.
In Wrap mode, the recorder will continue recording when
full, overwriting the oldest data readings with the newest.
16. If using the Record Internally function, select the maxi-
mum number of intervals from the dropdown list. If the
ADFM serial data is output to an Isco 4-20 mA Analog
Module, select the same number, or 1 less, than the Data
Interval.
17. Under Data Format, select Reduced.
18. The reading interval for Record Raw Data (Figure 2-12,
below Data Format) is based on the sampling (reading)
interval. Recording raw data for a single reading includes
additional diagnostic information embedded within the Q,
V, and D reading. The additional raw data creates a larger
file.
The recommended raw data interval is 10 minutes, i.e., if
the sample interval = 1, the raw data interval would be
every 10 readings; if the sample interval = 10, the raw data
interval would be every 1 reading, etc.
19. Click OK to save the programming information.
