PARAMETER DESCRIPTION
Displays information on the state and calibration of the electrochemical sensors:
Ok No problem detected
absent The sensor was not detected
err data Memory data error of the sensor
unknown It is necessary to update the FW of the device
err pos The sensor has been installed in the wrong position
err cal Calibration error (sensor not calibrated)
err curr Currents outside the range
err cfg Do not use this sensor as it has not been accepted on the screen "types of sensors".
Also, from this screen the user can access the identification data of the sensor: type, serial
number, date of manufacture and calibration. There are also the measured currents; in this way
it is possible to perform a quick diagnosis in the event of a malfunction.
SEE SECTION 9.7.1.
Tests the tightness of the gas probe pneumatic path.
SEE SECTION 9.7.2.
When instrument powers on, the firmware performs a full check on the physical Eff. tot of all
types of HW memories installed on the instrument, as well as on the integrity of the data stored
into them. Any issue is evidenced in the screen 'Memories Diagnostics'. Should this happen it is
advisable to turn the instrument off and then on again. In case the problem is permanent or

pump during an autozero cycle.
SEE SECTION 9.7.4.
It is possible to make a recalibration of the instrument’s gas sensors with suitable known
concentration gas cylinders.
The access to the sensor recalibration is password protected, the password is ' 1111 '.
