6712SR Refrigerated Sampler
Section 5 Extended Programming
5-30
Bottle Full Detection – The sampler can detect a full bottle
condition when collecting samples in a single bottle (composite
sampling). When the sampler detects a full bottle, it stops the
sampling routine.
A BOTTLE FULL condition will also stop a sampling routine
that is set to RUN CONTINUOUSLY.
The Bottle Full Detect screen allows you to enable or disable this
feature. Selecting “YES” enables the sampler to detect a full
bottle and stop the sampling routine. Selecting “NO” disables
this feature. The Bottle Full Detect setting is part of the sam-
pling program. Because it is a program setting, full bottle
detection can be enabled or disabled for each of the four extended
programs. If the Bottle Full Detect setting is critical to your sam-
pling program, always check this Software setting after you
select a different Extended Program.
This feature relies on a post-purge after each sample. When
using the Bottle Full Detect, make sure that post-sample purges
greater than 100 are used.
Bottle Full Detect is always disabled in the Standard Pro-
gramming mode.
Display Backlighting – The display has a backlight that is
adjustable so that the backlight is always off, timed or always on.
In the timed backlight mode the sampler turns the backlight off
after detecting no key strokes within 60 seconds. Any keystroke
(except ON-OFF) turns the backlighting on again. In this mode
the backlight must be on before the sampler accepts a menu
choice or number entry. If you press a key and a screen does not
respond, it is because the keystroke turned the backlight on.
It is recommended that you use either BACKLIGHT ALWAYS
OFF or TIMED BACKLIGHT when using a battery.
Event Marks – The sampler generates an event mark at each
sample event, sending it through the flow meter connector to a
connected instrument. The event mark may also control an
external device; a connected solenoid relay, for example. When
using the event mark for a data logger or to control external
devices, you may need to adjust the mark by changing the factory
settings.
The event mark is adjustable through the software setup screens.
You can set up the sampler to generate an event mark for
EVERY SAMPLE or for COMPLETE SAMPLES.
If you select COMPLETE SAMPLES, the sampler sends a
three-second pulse only after it successfully collects a sample.
The sampler will not send an event mark if an error occurs, such
as “No Liquid Detected.”
If you select EVERY SAMPLE, the sampler will send an event
mark every time a sample is initiated. The event mark signal can
be a:
• 3-second pulse at the beginning of the pre-sample purge.
