Adjusting alarm set points
The following procedure is very similar for setting either Alarm 1 or Alarm 2:
Whilst the
Analox
CO
Clear
is switched on, enter Technician Mode by
pressing the mode switch 3 times. If entered successfully the green LED
will flash off for 1.5 seconds and on for 0.5 of a second.
From Technician Mode, press the Mode switch 2 times to set Alarm 1 or 3
times to set Alarm 2. The buzzer will bleep on each press. If this is done
successfully, the instrument will show the Fault indicator and the
appropriate Alarm indicator. If this is done inadvertently, or if another
mode is selected, press the Mode switch once to return to Technician
Mode and then repeat this selection.
The display will indicate the present value of the alarm.
Press the Mode switch twice to proceed to define a new setting, or once to
abort and return to Technician Mode.
When setting Alarm 1 or Alarm 2, the display will show the maximum
display value (full scale).
Press and hold the Mode switch. The displayed value will count down at
approximately one count per second. Release the switch when the
displayed value is equal to the desired alarm value.
Upon release of the Mode switch, the display will continue to show the
new value. Accept the new setting by pressing the Mode switch twice, or
alternatively ignore the new setting by pressing the switch once. This will
return to the Technician Mode.
To exit from Technician Mode, press the Mode switch once. The
Analox
CO
Clear
then restarts by performing the normal power on sequence (4
flashes).
