Use <UP> or <DOWN> to set the NO2 recalibration mode
timer to Disable, 1, 2, 3 years or Reset. The default is 1 Year.
When disabled, the device will not sound the buzzer or provide
LCD and status LED indication when the NO
2
sensor requires
recalibration. When set to 1, 2 or 3 years, the Re-Cal alarm will
activate to indicate that the NO
2
sensor requires recalibration. If
set to Reset and <MENU> is pressed, then the Re-Cal condition
for the NO
2
sensor is cleared, the NO
2
Re-Cal timer is reset and
the NO
2
Re-Cal mode remains at the previous setting. The timer
automatically resets if the NO
2
sensor is replaced. If the desired
time has already been exceeded, then it cannot be selected. If
the NO
2
sensor is calibrated with gas via the User Menu then
the timer will be automatically reset.
Use <UP> or <DOWN> to set the Alarm Mode to Auto or
Manual. The default is Auto. This setting controls how Alarm1,
Alarm2 and the buzzer alarm resets back to Normal mode. For
the Auto setting, the device will reset the alarms automatically
once the gas level drops below the set alarm thresholds. For
the Manual setting, the gas level must be below the alarm
thresholds AND the user must press the TEST switch on the
device to reset the alarms.
