8.3.7.2 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 26 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 26 for more information on operation in Search Mode.
8.3.7.3 Pump Speed
If the MultiRAE is equipped with a pump, the pump can operate at two speeds, high and low. Running at
low speed is quieter, extends pump lifespan, and conserves a small amount of power. There is almost no
difference in sampling accuracy.
8.3.7.4 Zero At Start
If your MultiRAE has been configured to perform a zero (fresh air) calibration upon startup, called Zero
At Start, then the startup routine is interrupted so that you can perform a fresh air calibration for all
sensors prior to using the instrument.
If you do not want to perform a zero calibration, press [MODE] to bypass it. If you start a zero calibration
and want to abort it, press [N/-], and the calibration stops and the main display is shown.
8.3.7.5 Fast Startup
Fast Startup reduces the amount of time between when the instrument is turned on and is ready for use. It skips
showing you many settings and is best suited to environments where the MultiRAE is turned on and off very
often during a given day. If Fast Startup is not selected, then when the instrument starts, it shows you details of
each sensor, including calibration information, high and low alarm settings, etc.
8.3.7.6 Temperature Units
The display unit of the internal temperature sensor can be switched between Fahrenheit and Celsius.
8.3.7.7 Language
English is the default language, but other languages can also be selected for the instrument.
8.3.7.8 Site ID
Choose and enter an 8-digit Site ID to uniquely identify the particular site where the instrument is to be
used. The first four digits can be an alphabet letter or number, while the last four digits can only be
numbers. This Site ID is included in the datalog report.
Note: Advance through the alphabet and numbers (0 through 9) by one with each press of the [Y/+] key.
To scroll quickly, hold down the [Y/+] key for as long as you want it to scroll rapidly.
8.3.7.9 User ID
Enter an 8-digit alphanumeric User ID to uniquely identify a user. This User ID is included in the datalog
report. The first four characters of a customized User ID act as an identifier for the monitor on the screen
of the EchoView Host Wireless Mini-Controller to which the MultiRAE is wirelessly connected.
