Revision 5 56 August 2021
Below the Back Purge Indicator are two check boxes which can be used to manually set the
analyzer into back purge or sampling mode. To choose which mode is active, select the
desired mode using the F4 / F3 buttons and press
↵
to choose. Alternatively, pressing the
F6 key will switch to the currently inactive mode (i.e. pressing F6 while the analyzer is
sampling will cause it to switch to back purge mode and vice versa).
Prior to performing any maintenance, particularly if any sample system tubing is
to be disconnected, the analyzer should be placed into back purge mode and
purged for at least 5 minutes. This will prevent any toxic gases from remaining in
the sample system if tubing is to be disconnected.
If Sample is selected but the back purge indicator remains red, this indicates that a fault
condition likely exists. Once the fault condition(s) are cleared, the analyzer will automatically
return to sampling mode after first performing a zero calibration cycle. If the analyzer is set
to back purge mode while a fault condition exists, the analyzer will NOT automatically return
to sampling mode when the fault condition(s) are cleared.
