6b PROGRAM STOP?
When the advanced program features are enabled, this message appears after the
delay time/date has been entered. Press
YES to enter the time and date for the
program to stop. After the stop time and date have been entered, the display advances
to the prompt shown in item 6c. If you press NO, the sampler will remain dormant until
the delay time is reached. This will prompt item 7.
6c PROGRAM RESTART?
This message appears after you enter the desired program stop time and date. Press
YES to allow the user to enter the time and date on which the program will restart.
Press
NO to cause the sampling program to stop when the sampler's clock reaches the
stop time and date entered in item 6b.
You can enter up to 12 start/stop intervals by entering successive
YES responses and
time/date entries to PROGRAM STOP? and PROGRAM RESTART?.
7TIMED MODE
If selected, the sampler will operate on a timed cycle basis. Press
YES to prompt the
user to enter the number of minutes desired for the time interval between samples.
Press
NO to prompt the question described in item 8.
7a VARIABLE INTERVAL
Press
YES to enter up to 99 different time intervals between samples. When the last
desired interval is displayed, press the NO key to repeat the last interval for all
subsequent samples.
7b INTV = _ _ _ _MIN Enter the value for the interval between samples (in minutes).
8FLOW MODE
Press YES, the cause the sampler to operate on a flow proportional basis. It will prompt
the you to enter the number of flow signals that you want the sampler to count down
between samples. Press
NO to prompt the question in item 7.
8a VARIABLE INTERVAL
Press
YES to enter up to 99 different flow pulse intervals between samples. When the
last desired interval is displayed, press the NO key to repeat the last interval for all
subsequent samples.
8b INTV = _ _ _ _CNTS
Enter the value for the number of pulses (counts) that you want to accumulate between
samples. To determine the appropriate number, refer to the programming instructions
for flow proportional operation in section 5.15.
8c TIMED OVERRIDE
This message appears only if the Advanced Program is enabled. If a sample is not
collected in proportion to flow within a specified time period, a sample is taken when
the default time elapses. Press
YES to enter a default time. The default time resets after
each sample collection. The message in item 8d will also appear.
8d MAX TIME = _ _ _MIN Enter the desired default time.
9 OTHER CHANGES
Press NO to retain the previously entered program entries for all remaining
programming steps, and return to the
READY TO START standby state. Press YES to
change the previously programmed entries for all items 10 through 16.
10
COMPOSITE MODE,
CONTINUOUS MODE
This message appears if only one bottle is entered for the total number of bottles in the
parameter entry mode. Press
YES to the CONTINUOUS MODE? prompt to take samples
at the programmed interval. The program will terminate only with a full bottle when
using the full bottle float switch (Cat. No. 8847). Press NO to cause the display to read
SAMPLES = _ _ _. This permits you to enter the desired number of samples, after which
the program will terminate.
10a COMPOSITE MODE
With the advanced program features enabled, this question appears if more than one
bottle is entered in the parameter mode (
ENTER NUMBER OF SAMPLE BOTTLES, TOTAL
BOTTLES = __ __). Press YES to collect sample in all bottles with each sample initiation.
After sampling, the distributor arm returns to bottle 1 and waits until the next initiation
where the cycle repeats for subsequent samples. The display then indicates the
message explained in item 10b.
In this mode, all bottles represent the same composite sample. This 'multiple bottle
composite' sampling feature is particularly useful when using 2, 4, or 8 bottles with a
different preservative in each, or when it is necessary to split the sample for
independent analysis.
10b CONTINUOUS MODE?
Press
YES to collect samples as described in item 10a. Press NO to display the
message explained in item 10c.
