9.3.11 Monitor
The submenus under “Monitor” control the LCD’s contrast, operation mode, pump speed, and other
parameters. Press [N/-] to advance through the submenus, and when you reach the last one, it returns to
the first selection.
9.3.11.1
LCD Contrast
The display’s contrast can be increased or decreased from its default setting. You may not need to ever
change the default setting, but sometimes you can optimize the display to suit extreme temperature and
ambient brightness/darkness conditions.
Use the [Y/+] and [N/-] keys to decrease or increase LCD contrast, respectively (the bar graph aids in
setting it). When you are done, press [MODE] to select “Done.” If you have not made a change, it exits to
the submenu’s next selection. If you have made a change, you are prompted at the next screen to press
[Y/+] to save the change or [N/-] to undo the change and exit to the next submenu selection.

Operation Mode
There are two operation modes, outlined below.
Hygiene Mode
When the MultiRAE is in Hygiene Mode, it continuously monitors, and if datalogging is on, it saves data
continuously. Refer to page 42 for more information on operation in Hygiene Mode.
Search Mode
When the instrument is in Search Mode, it only samples when you activate sampling. When you see the
display that says, “Ready…Start sampling?” press [Y/+] to start. The instrument automatically assigns a
new Site ID to each measurement you take. The pump turns on and the instrument begins collecting data.
To stop sampling, press [N/-] while the main display is showing. You will see a new screen that says,
“Stop sampling?” Press [Y/+] to stop sampling. Press [N/-] if you want sampling to continue. Refer to
page 42 for more information on operation in Search Mode.
