For those situations where water droplets may be present in the sample
line, you will need to install a water trap between the Naon tubing and
the incubator’s sample port as described in Section 2.14.
After completing a test, continue to run the pump while sampling fresh
air until the reading is below 0.1. This will purge out any residual CO
2
and moisture before proceeding to the next test.
2.6 Storing Readings
There are two reading-storage modes available:
• Snapshot
• Continuous Data Logging
Pressing the f
1
button once stores (takes a snapshot of) the reading
shown on the display.
Pressing and holding down the f
1
button for at least 2 seconds starts the
continuous data logging of the readings at a preset interval (factory set
at 30 seconds).
The analyzer can store up to 100 snapshot readings and 800 sets of
continuous-data-logged readings. Once the storage capacity has been
exceeded, the latest readings will overwrite the oldest stored data.
The stored data can be downloaded to a personal computer using the
analyzer’s IrDA link and the optional BACH-COM software. This soft-
ware can also be used to alter the data-logging interval, and produce
tables and plots of time-based CO
2
readings.
2.7 Battery Low Display
When the battery voltage falls below a pre-determined level, the display
will alternate between its normal gas display and
In addition, the beeper will emit three rapid notes every 30 seconds. At this time
the analyzer should be given a full charge per Section 3.6 as soon as possible.
