Logging Data 3-5
March 2008
END DATE Prompt
13.
Press
[F1]
to accept the displayed end date or press
[F2]
to enter a
different end date. To end the log today, press
[F3]
.
•
If
OK
or
TODAY
was selected, proceed to the
TIME INCREMENT
prompt. Refer to Figure A-7 on page A-7 for a flow diagram of
the programming sequences.
•
Otherwise, complete the steps below.
a.
Enter the desired Year and press
[ENT]
. The acceptable range is
0 to 99.
b.
Use the [
←]
, [
→]
and
[F1]-[F4]
keys to select the desired
Month .
c.
Enter the desired Day and press
[ENT]
. The acceptable range is
1 to the number of days in the selected month (28, 29, 30 or
31). The program proceeds to step 15.
DURATION Prompt
If a circular log was specified, the programming sequence continues
here after the log start time and/or start date is entered.
14.
Press
[F1]
and enter a log duration in hours or press
[F2]
and enter a
log duration in days. When the desired value has been entered,
press
[ENT]
. The program proceeds to step 16.
LOG TIME Prompt
If
TIMED
was selected at step 12, the programming sequence continues
here.
15.
Use the [
←]
, [
→]
and
[F1]-[F4]
keys to select the desired log
duration.The available options are: 10min, 30min, 60min, 3 HR, 6
HR, 12 HR and 24 HR.
TIME INCREMENT Prompt
Regardless of which of the various options were selected during the
previous programming steps, all of the paths converge at this point.
16.
Use the [
←]
, [
→]
and
[F1]-[F4]
keys to select the desired Time
Increment . The available options are: 5sec, 10sec, 30sec, 1min,
3min, 6min, 12min, 30min and 60 min.
The time increment is the frequency at which the Model GS868 takes
and records data measurements. If any reading takes longer than the
programmed time increment, the log is filled in with the next
consecutive reading. For example, assume that a velocity value of 3
ft/sec is recorded at 12:00:00 in a log with a time increment of five
seconds. If the next reading is 8 ft/sec and it takes the meter 12
seconds to read this value, then both of the missed readings (12:00:05
and 12:00:10) will be filled in with the 8 ft/sec value.
