Menu Access / Passwords 

 

The analyser has an option to set a password that will restrict access to the menus.  
The password menu is disabled by default in the factory.  If you wish to password 
protect the analyser press ENT and scroll down to the PASSWORD option (Menu 
option 11).  Pressing ENT again will ask you for the default password which is 

“0000”.  Enter this using the UP and DOWN arrows.  Once the password has been 
entered successfully you can chose between ENABLE and DISABLE in the menu 
using the UP and DOWN keys. 
 
The other option is to RESET the password to a new value.  The password must be 

4 digits long and can be any combination of numbers from 0-9.  Make sure that the 
new password is noted down! 
 
If the password function has been enabled then in the future each time the menu 
system is accessed then the password prompt will display.  After the correct 

password is entered then the full menu will be accessible.  You can make as many 
changes as you want to the options and only press ESC once you have finished.  
Pressing ESC takes you out of the password protected area and you will have to re-
enter the password to go back in again. 
 

If the password has been forgotten please contact Cambridge Sensotec who will 
advise you on how to recover it.

Rapidox Calibration 

 
Full calibration is a simple procedure requiring only two or three gases (one of 
which is normally air – 20.95%).  The two gas values are user-selectable and can 
be changed by using the front keypad (2) or the communications software 

described in section 6, and the calibration values can be stored on file for later 
use. 
 
Care must be taken to calibrate the analyser so that, whenever possible, the range 

of measurement lies between the two calibration point extremes.  For example, if 
you are working at 10ppm but have calibrated the analyser between 21% and 
100% then the analyser will be inaccurate.  You would need to calibrate at, say, 
1ppm and 21% to be sure of good accuracy.  The procedure is as follows: 
 

1)

 

Bearing in mind the points made above, decide which two (or three) gases 
you are going to use for calibration.  If you are constantly working at a 
particular range of compositions then it would be wise to obtain small 
cylinders of calibration gas with analysis certificates.  Cambridge Sensotec 
can supply these.  Press the ENT button on the front panel keypad (2) to 

access the menu system.  The calibration function is option 1 on the menu 
list, which can be scrolled using the UP and DOWN arrows.  Press ENT 
again to enter the calibration menu.  Use the UP and DOWN arrows to
