temperature, relative humidity, calculates dew point, wet bulb, and %
outside air, and measures one (1) additional parameter. The Model 8554 will
also measure CO. The instruments have three main modes of operation:
Survey, Sample, and Data Log.
Survey mode: When the Q-T
RAK
Plus monitor is first turned on, it will
be in the Survey mode. This mode is used to display the real-time
readings of the sensors. The instrument will update the displayed
readings once each second.
Sample mode: The Sample mode is used to capture a 10-second,
averaged reading of all the parameters. These “single sample points”
may be stored in memory and can be displayed later, or downloaded to a
computer using the T
RAK
P
RO
software.
Data Log mode: The Data Log mode is used to record readings over a
period of time, and store these readings in the instrument memory. Data
files may be downloaded to a computer for later analysis using the
T
RAK
P
RO
software. Q-T
RAK
Plus has three different data log modes.

instrument's power-up sequence consists of a startup screen that displays the
instrument’s model number, serial number, firmware version, available
memory, date and current time. The display will also show various status
messages. The startup sequence lasts for 20 seconds before entering Survey
mode. A reminder may appear when the instrument is due for servicing.
