Analyzer 2825/2830/2835
Instruction 19-9320 7
2.7 Current / Peak Gas Reading Mode
The analyzer can display either the current readings of all measure-
ments, or peak gas readings. While displaying a gas reading, pressing
and holding the f
3
button for 3 seconds switches the analyzer to its peak
reading mode. Note that a peak reading is the highest reading taken
since the analyzer was switched ON.
When using the 2825 / 2830 in its peak-reading mode, pressing the f
3
button toggles the display between ‘peak CO2’ and ‘peak O2’.
To return the analyzer to its current-reading mode, again press and hold
the f
3
button for 3 seconds.
To reset the peak gas readings back to the current readings, switch the
analyzer OFF and then back ON.
2.8 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 3 seconds starts the
continuous data logging of the readings at a preset interval (factory set
at 30 seconds).
The analyzer can store from 100 to 200 readings based on the analyzer’s
conguration. Logging will stop once the analyzer’s storage capacity has
been reached.
The stored data can be downloaded to a personal computer using the an-
alyzer’s IrDA link and the optional BACH-COM software. This software
can also be used to alter the data-logging interval; produce tables and
plots of time-based CO
2
readings; and clear all logged data from memory.
