Measurement Screens and Navigation
To navigate through the measurement screens repeatedly press ◄/► Arrows key from the Start
screen. (The start screen is the second screen you encounter after the initial splash screen.
Looking at the measurement screens clockwise (or pressing ► Arrow key), you will see the particulate
measurement screen. The subsequent screens that appear include the relative humidity and
temperature screen, the gas screen, the composite screen, and the air velocity screen. Depending upon
the sensors you purchased, the installed sensors, and the measurement setup you may see some
variations in the upcoming measurement screens in comparison to your instrument. These will be noted
(or explained in full detail).
Unit defined
While viewing your measurement data, you will want to have a good understanding of the abbreviated
units used on the instrument. These are listed in Table 5-1.

Explanation
OL
Over Load – This indicates a measurement (on the current screen) is above the maximum
value (for that sensor) which the instrument can measure.
UR
Under Range – A measurement (on the current screen) is below the minimum value (for
that sensor) which the instrument can measure.
ºF
Degrees Fahrenheit – This is displayed with readings for Temperature and Dew Point.
ºC
Degrees Celsius – This is displayed with readings for Temperature and Dew Point.
%
Percent- This is displayed for the percentage measurement for the pump flow rate, the
relative humidity sensor, and the Oxygen sensor.
ppm
Parts per Million – This is displayed with measurement readings of CO
2
, toxic gas, and
PID sensor(for VOCs).
ppb
Parts per Billion – This is displayed with reading of PID sensor (for VOCs).
mg/m
3
Milligrams per cubic meter – This is a unit of measurement (of mass per unit volume) and
is used for particulate measurements and PID PPM (PID sensor for VOCs).
μg/m
3
Micrograms per cubic meter – This is a unit of measurement (of mass per unit volume)
and is used for particulate measurements and PID PPB (PID sensor for VOCs).
m
3
Volume – Gravimetric volume for the particulate measurements.
mg
Mass in Milligrams – Gravimetric accumulator mass for the collected particulates.
m/s
Meters per second – This is the unit of measurement for metric air velocity.
ft/m
Feet per minute – This is the unit of measurement for air velocity.
