Thank you for purchasing this air flow
meter. This meter is specially designed
for HVAC&R application that combines
those required measurements, like Air
Velocity, Air volume, Temp., RH, WBT,
DP, and CO2 in one handy meter.
The Air flow cone compatibility also
helps in quick volume measurement.
Users can be freed from the hassle of
calculating dimensions.

MEASUREMENT
POWER ON/OFF
Press to turn on the meter. The
screen shows full display with blue
backlight on and enter normal mode.
(Model 8916/8917). For model 8919,
it proceeds 30 seconds warm up when
turned on, then goes into normal mode.
Press again in any mode to turn
off the meter.
The meter is preset auto sleep in 20
minutes of inactivity. To disable this
function, hold down and for 2
seconds to turn on the meter while it is
off. It shows “n” on the LCD (see Fig.A)
and goes into normal mode(or 30 sec.
warm up for model 8919) and won’t
turn off itself until is pressed or out
of voltage.

SWITCH DISPLAY
When the meter is turned on, it shows
the current readings of air velocity on
the upper display and air temp. on the
lower(see Fig.B). To switch display of
other measurements, press or .

Short press , the upper display will
cycle among air velocity, RH, and
CO2 (8919 only).
And short press , the lower display
cycles among air temp. air volume
WBT(wet bulb temp) DP(dew
point temp)(Fig.C).

AIR VOLUME
To measure air volume, it is necessary
to get the outlet dimensions. Go to
Setup mode and input the AREA value
first before taking measurement. (See
page 9 , P2.0)
CMM
After AREA setting is completed, press
to switch the display to air volume
and the measured air volume will be
displayed on the lower LCD.
Measure with airflow cones
Two airflow cones are available
for using with this anemometer and
are sold as a set.

RH(8917/8919 only)
The capacitive humidity sensor is built
in the center of the vane to measure air
flow relative humidity and is used for
calculating dew point and wet bulb
temperatures.
Press to switch to RH display. It
shows measured RH readings on the
upper display. And it is also possible to
display with RH offset. Go to Setup
mode (see page 9, P3.0) and input
offset value, then the displayed readings
will be the measured data with offset.
To measure air volume with use of an
airflow cone. Just plug on the cone and
the meter will automatically recognize
it and shows a on the display(Fig.C).
Then the meter will calculate the air
volume by the default dimensions
despite of any AREA value is input.
Note:
Be sure the airflow cone is well mounted
and locked tight. (See pic.1)

MIN/MAX
In normal mode, long press for 3
seconds and it displays the minimum
readings of all parameters since power
on with MIN icon on the top. Long press
this button again, it shows the maximum
readings with MAX on the top. (Fig.D)
Long press again and it returns to the
normal mode.

CO2 (8919 only)
Model 8919 features additional CO2
measurement for HVAC application.
The NDIR CO2 sensor is built in the rear
side of the meter. Press to switch
to CO2 display and the current reading
will show on the upper LCD.
For places in high altitude, the pressure
compensation needs to be considered
in order to get accurate CO2 readings.
Go to Setup mode P4.0 and input the
pressure value according to your
location before taking measurements.
DATA HOLD
In normal mode, press and the
current readings are fixed on the LCD
with HOLD icon on the top and won’t
change until a second press on .

Timed average
In normal mode, press for 2 seconds
and it goes into multi-point average.
Press it again to enter timed average
mode. (See Fig.G, the upper display shows
the duration time in second, the maximum
time is 19999 seconds, and the lower is the
measured reading)

AVERAGE
This meter calculates multi-points mean
and timed average of all parameters.
Multi-points average
In normal mode, press for 2 seconds
to enter multi-point average mode.(See
Fig.E, the upper display shows the record
number and the lower is the measured reading)
- Press to record readings.
- Press to see the multi-point mean
once all data is recorded. It shows the
average readings with flashing” “.

SETUP
The setup mode is for those related
parameters setting that can ensure
more accurate measurements.
It includes:
P1.0: Unit selection
P2.0: AREA size
P3.0: RH offset
P4.0: Pressure input (model 8919 only)
P1.0: Unit selection
In P1.0 (Fig.I), press to enter units
selection (Fig.J). Then press or
to switch from Metric to Imperial unit.
The units include air velocity(m/s, fpm),
temp.(C, F), air volume(cmm,cfm), and
