6. Error messages 

During calibration and measurement, the instrument displays error messages in case of problems: 

Error messages 

Error 

Description 

Solution 

1 

During calibration, the value is out of the 

acceptable range 

  Calibrate at 0% with fresh standard 

  Check the integrity of the probe and 

luminophore 

  Replace luminophore 

2 

During calibration appears when you 

press the 

  button with unstable value 

  Wait for 

  icon 

3 

It appears if during the calibration the 

value does not stabilize within 3 minutes 

  Check the integrity of the probe and 

luminophore 

  Replace luminophore 

6 

The reading is out of the measuring limits 

  Check the connection between the probe and 

the instrument 

  Check the integrity of the probe 

  Perform a new calibration 

 

Calibration expired 

  Perform a new calibration in air 

8 

The LDO 

sensor doesn’t communicate 

with the instrument 

  Check the connection between the probe and 

the instrument 

  Contact technical support 

9 

The built-in barometric sensor is not 

working properly 

  Replace the batteries 

  Contact technical support 

 

 

 

 

7. Restore to factory default setting 

To restore the factory settings, access the parameter 

P5.5

 of setup menu. 

Press 

, the display will show 

NO

 flashing. 

With the 

  or 

  keys choose 

Yes

 and confirm with the 

  key. 

This  feature  can  be  very  useful  in  case  of  errors  or  when  making  incorrect  calibrations  and  /  or  have 

calibration problems.
