Replace the desiccant filter when its silica gel turns a pinkish color. Note
that the filter’s silica gel can be rejuvinated by either running pure N
2
through the filter at a low flow rate, or by baking the filter in a 250°F
(120°C) oven until its blue color returns.
When storing the desiccant filter, install rubber caps P/N 19-0001 on
both ends of the filter. The caps will seal the filter when not in use and
extend its life.
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.
