15 - Active Sampling
This mode allows the operator to program active sampling periods for each day of the week. The operator
enters the days to sample and an active time period (start time to stop time) for each day that sampling is to
occur. The operator also chooses if the sampler will restart sampling (clears program parameters) or resume
sampling (keep the program parameters from the last active period) when a new active day and time is
started. In order for Active Sampling (
*
15) to work correctly, the sampler clock must be correctly
set, and a sampling program (TIME, FLOW,
*
02,
*
05) must be programmed.
If an end of sequence event (such as a bottle full) occurs before the active sampling period expires, then the
active time period will have no effect. If the active time period expires while a sample is in process the
sample will be completed and no more samples will be taken. After active sampling is set up in Program15,
the operator then programs the sampler with whatever time or flow-paced program is required. During the
active time period of an active day of the week, the sampler collect samples based on the sample program
that is running. At the end of the active time period no more samples are collected until the next active
day/time period.
If Active Sampling is programmed, The right-most position (position 20) on the top line of the LCD display
indicates the Active Sampling status. A blinking “A” indicates that the sampler is in an active time period
and sampling is allowed. A blinking “I” indicates that the sample is in a inactive time period and no
sampling is allowed. If the last active period of the week has passed, the second line of the display indicated
“NO MORE”, meaning that no more sampling will occur that week. A week starts on Monday and ends on
Sunday. Active sampling is turned turn off by entering the Program
15 mode and entering a 0 at the
ACTIVE SAMPLING? prompt.
The major use of the active sampling period will be in industrial monitoring situations where (as dictated by
the EPA) a valid sample period cannot be longer than a specified period of time (i.e., 24 hours), or in
sampling situations were sampling is only required for a certain part of the week (i.e., Thursday 8:00AM
until Sunday 8:00PM).
Display on LCD Explanation
SAMPLER READY
04/30
04:30:02
This display indicates the sampler is ready to program and
alternately displays the current time and date. Press the
*
key
to begin programming.
The sampler is now prompting for a star mode to be input. Enter
ENTER PROGRAM #
__ __ 07/30FRI
the numbers which represent the star mode of choice, in this
example 15, and press <ENTER>.
ACTIVE SAMPLING?
0 04:30:02
The sampler then asks if Active Sampling is to be turned on. Enter
a “1" and press <ENTER> . To turn off Active Sampling, enter a
“0" and press <ENTER>. If Active Sampling is turned off, the
display will return to the SAMPLER READY prompt.
