BLZZRD Portable Refrigerated Sampler
Section 5 Extended Programming
5-30
How Does It Work? –
The primary sampler sends a disable
signal out its flow meter connector. The secondary sampler
receiving the signal is held disabled until the primary sampler
completes its program.
When using a flow meter or flow logger a Dual Sampler Mode to
Flow Meter cable must be used. This cable is constructed so that
the pacing instrument receives only the event marks. Therefore,
a connected flow meter will not receive a bottle number signal,
nor will it be able to control the sampler inhibit.
5.15.5 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.
5.15.6 Display Backlighting
The display has a backlight that is adjustable so that the back-
light 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.
5.15.7 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.
