( Fig. 5).
This includes:
 the current gas concentration

 the value for the upper reaction point ("
HI" "ALARM")
 the minimum oxygen concentration ("
LO") – only for oxygen version
 the measured peak values ("
HI", "LO")
The measured peak values can be deleted. For this, press the test
button when displaying the relevant value.
During the display of the peak value, press the [TEST] key:
 Value is deleted

 If an IR interface is detected in the test mode, the instrument bypasses
the IR mode.
 If no IR interface is detected in test mode within 30 s, or the [TEST] key
is pressed, the instrument exits this mode.
