PARAMETER DESCRIPTION
Through this sub menu the user can turn on and off the instrument Bluetooth wireless
communication with a PC or PDA.
This allows the current time and date to be set. The user can select the date and hour format
either in USA (American) or EU (European) mode.
SEE SECTION 9.3.2.
The display contrast may be increased or decreased by acting on cursor keys. This operation
may be performed even when the introductory screen is active.
SEE SECTION 9.3.3.
In this sub menu the user can turn the gas suction pump off or back on. Also, if the pump is on,
the user can view the flow of the pump in litres per minute.
It is not possible to turn off the pump during an autozero cycle.
SEE SECTION 9.3.4.
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.
Allows to configure the micromanometer input (optional) as P+ or P- port. In case P- is selected,
the sign of pressure is inverted.
SEE SECTION 9.3.6.
WHEN THE INSTRUMENT BLUETOOTH INTERFACE IS TURNED ON, THE
BATTERY LIFE IS REDUCED DOWN TO 10 HOURS.
CO Auto-Dilution feature must only be considered as a means of
protection for CO sensor, as its activation widens both the accuracy and
resolution of the CO measurement.
