Programming & Calibration
The Q-RAE PLUS monitor is built with a microcomputer to
provide programming flexibility for a variety of users.
Authorized users can calibrate the monitor, change the
measurement gas, change the alarm limits, change site ID,
user ID, datalogging interval, real time clock, etc.
Note:
The real time monitoring of gas concentrations
continues while in the programming mode. However, during
calibration or review datalog procedures, real time monitoring
pauses until the procedures are completed. Datalogging also
pauses automatically upon entering programming mode and
resumes upon exiting.
3.1. Programming
Mode
To enter the programming mode, hold down the
[MODE]
and
[N/-]
keys simultaneously for three seconds. To exit this mode,
press
[MODE]
repeatedly until the main concentration display
shows.
There are also three security levels to control the access of the
Q-RAE Plus programming mode.
•
“Level 2” security (factory default) offers complete
access to the programming menus without a password.
•
“Level 1” security requires a 4-digit password to enter
programming menus. The Factory default is “0000”.
•
“Level 0” security does not require a password, but
offers only limited access to the programming menus.
In Basic mode, calibration is available but modification of the
other monitor settings is limited. Refer to Appendix A of the
Long Form Manual for a table of the detailed accessibility to the
programming functions.
The programming functions are organized in a multiple tier
menu structure. The main programming menu in advanced
mode is shown below:
