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.

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)

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.

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 .

CO2 CALIBRATION
The meter is calibrated at standard
400ppm CO concentration in factory.
2
It’s suggested to do manual calibration
regularly to maintain good accuracy.
CAUTION:
Do not calibrate the meter in the air
with unknown CO concentration.
2
Otherwise, it will be calibrated as
default and leads to
inaccurate measurements.
400ppm
400ppm calibration is suggested to be
done in outdoor fresh air that is well
ventilated and in sunny weather.
400ppm calibration
Note:
When the accuracy becomes a concern
after a long time use, return to dealers
for standard calibration.
CALIBRATION
RH CALIBRATION
The humidity calibration of this meter
requires specific fixture and cannot be
done by end users. Please contact the
dealer for calibration service.
Place the meter in the calibration site
and follow the below procedure to
complete the 400ppm calibration.
Fig.O Fig.P

12
LOW-BATTERY
When the battery voltage falls below the
measurement required range, shows
on the LCD. Replace with fresh batteries
to ensure accurate measurements.
2. During calibration, a CO2 reading in
the range of 380 to 420ppm will be
flashing on the upper display.(Fig.U)
Fig.T Fig.U
ppm
NOTE:
Be sure the batteries are with full
voltage during the calibration to
prevent from interruption and fail
in the calibration.
1. While the meter is turned off, hold
down , and simultaneously
to enter CO2 calibration mode. It runs
30 seconds countdown with CAL at
lower display(Fig.T), and then starts
400ppm calibration.
3. Wait for 10 minutes until the reading
stops flashing, the 400ppm calibration
is completed and it returns to normal
mode automatically. .
To abort the calibration, turn off the
meter at any time.

Send to the dealer for repair.

14
3) DP and WBT
E04: Temp. or RH error.
Check temp. or RH error

E03: Velocity is over high range limit.
Try in range measurement. If
it still shows in range velocity,
recalibrate it send for repair.
5) Air volume
E03: Reading exceeds display limit.
Check if the outlet area setting
is correct.
E04: Air velocity error.
Try recalibration or send for
repair if it still can’t work.
6)CO2

Put the meter in room temp.
for 10 minutes and if E03 still
shows, recalibrate it or send
for repair.
E01/E33: Voltage too low or CO2
module error.
Check if battery low icon showed
on the LCD, if yes, replace with
new batteries.
Try recalibration, or send for
repair if it still can’t work.
