This menu is used to configure the instrument's reference parameters described below:
Bluetooth (When applicable):

or PDA.

WHEN THE INSTRUMENT BLUETOOTH INTERFACE IS TURNED ON, THE BATTERY LIFE
IS REDUCED DOWN TO 10 HOURS.
Calibration
It is possible to make a recalibration of the instrument's gas sensors with suitable known concentration gas
cylinders. Recalibration of Oxygen (O2) sensor is not availbale since it is already recalibrated during every
3
autozero sequence. See 'MAINTENANCE' section.
Display contrast:
The display contrast may be increased or decreased by acting on cursor keys
performed even when the introductory screen is active.
Time/Date:
This allows the current time and date to be set. The user can select the date and hour format either in EU
4
(European) or USA (American) mode.
CO Auto-Dilution (When applicable):
The CO sensor is protected by a pump which, in case of need, can inject clean air in the gas path in order to
dilute the gas concentration measured by the sensor. This function can be either triggered by the overcoming of
a CO concentration threshold which can be set by the user or, in case it is known that the flue gases contain high
CO concentration, kept enabled any time, independently of CO concentration.
5
CO Auto-Dilution feature must only be considered as a means of protection for CO sensor,
as its activation heavily deteriorates both accuracy and resolution of the CO measurement.
Micromanometer
Allows to configure the micromanometer input (optional) as P+ or P– port. In case P– is selected, the sign of
pressure is inverted.

Buzzer
This sub-menu permits to activate or deactivate the instrument buzzer.
