CFM0.01 to 322.92 feet square
1) Power on the instrument by pressing the ON Button
(3-1, Fig.1).
2) Select the Anemometer function by pressing Function
Button (3-6, Fig.1).
3) Press the Unit/Zero Button (3-4, Fig.1) to select unit
that you want and then face the Anemometer Sensor
(3-7, Fig.1) to the source of wind.
4) Allow time for the reading to become stable and note the
value indicated. From a practical point of view the velocity
may fluctuate.
4-2 Temperature Measurement
(Thermocouple)
1) Power on the instrument by pressing the ON Button
(3-1, Fig. 1)..
2) Plug a type K thermocouple probe in the Thermocouple
Input Socket (3-8, Fig.1).
3) Select the Temperature function by pressing Function
Button (3-6, Fig.1)
4) Press the °F/°C Button (3-5, Fig.1) to select °F or °C
unit.
5) Contact the Thermocouple Sensor Head with measuring
object and the reading value will be displayed on the LCD
display.
Measuring Consideration of Temperature
Measurement ( Thermocouple )
* Please make sure the polarity is correct when you plug a
thermocouple probe in the Temp. input socket.

Page 9
* The temperature difference between thermocouple
probe and thermometer will cause an inaccurate
measuring result. Therefore, for the best measuring
and accuracy performance, whenever changing a probe
or plugging a new probe, thermal equivalent between
probe plug and meters input socket is a necessary
condition. Thermal equivalent procedure may take few
minutes and apply only when the probe has been exposed
to an ambient temperature different from the meter.
4-3 Humidity & Ambient Temperature
Measurement
1) Power on the instrument by pressing the ON Button
(3-1, Fig. 1).
2) Select the Relative Humidity function by pressing
Function Button ( 3-6, Fig. 1 ).
3) At the mean time the reading value of relative humidity
and temperature will be displayed on the LCD display.
4) When the meter is applied in a new environment, a few
minutes are required to reach a stable condition.
4-4 Light Measurement
1) Power on the instrument by pressing the ON Button
(3-1, Fig.1).
2) Select the Light Measurement function by pressing the
Function Button ( 3-6, Fig. 1 ) until the light value is
displayed. The light display digits are oriented 180° from
the other function displays for easy exposure and output
reading of the light sensor.
3) Press the Lux/Ft-cd Button (3-5, Fig.1) to
select measuring unit Lux or Ft-cd .

Zero Offset Adjustment of Light Function :
* For best results zero the light sensor prior to use in a
dark environment. Placing the light sensor end of the
meter under a desktop or flat surface so as to block
any light can accomplish this. Then press the
Unit/Zero Button (3-4, fig.1) to set the meter
indication to zero.
* Zero point can drift due to environment temperature
and battery power change as well as for other reasons.
It is recommended that the zero be checked
frequently using the above procedure.
* Zero adjustment only can be executed if the measurement
Light value
< 20 Lux.
4-5 AIR FLOW (CFM. CMM) MEASUREMENT
1) Power on the instrument by pressing the ON
Button (3-1, Fig.1).
2) Select the Air Flow function by pressing
Function Button (3-6, Fig.1) until the display show
unit of CMM or CMM.
* Air flow unit CFM or CMM can be select by
* For the CFM measurement, the area size is feet square ,
the lower display will show F-2 .
For the CMM, the area setting size is from 0.01 to 322.92 feet
square.
* For the CFM measurement, the area size is meter square ,
the lower display will show m-2 .
For the CMM, the area setting size is from 0.001 to 30.000
meter square.
4) Use the hand to hold the meter,
face the Anemometer Sensor (3-7, Fig.1) to the
measured wind. In the same time the air flow value
(CFM, CMM) will show on the LCD display.
5. OTHER FUNCTIONS
5-1 Hold Function
Pressing the Hold Button (3-2, Fig.1) will freeze
the current reading value with a HOLD symbol on the
display.
5-2 Data Record Function
1)The Data Record function records & displays the maximum
and minimum reading values. Start the Data Record function
by pressing the REC Button (3-3, Fig.1) once.
There will be a REC symbol on the display.

Page 12
2) With the REC symbol on the display :
(a) Press the REC Button (3-3, Fig.1) once and the
Max symbol along with the maximum value will appear
on the display.
(b) Press the REC Button again, the Min symbol
along with the minimum value will appear on the display.
(c) To exit the memory record function, press the REC
Button continuously for at least 2 seconds. The display
will revert to the current reading.
(d) Clear the Max./Min. value recorded by pressing the
Hold Button (3-2, Fig.1) once. Previous recorded
Max./Min. value will be given up and then revert to the
REC. function keep on recording.
5-3 Auto Power Off Disable
In order to prolong the battery life, the instrument has Auto
Power Off function. The meter will switch off automatically if
no buttons are pressed for around 10 minutes.
6. BATTERY REPLACEMENT
1) When the LCD display shows symbol,
it is necessary to replace the battery. However measure
ment may still be made for several hours after the low
battery indicator appears.
2) Open the Battery Compartment / Cover (3-12, Fig.1)
and remove the battery.
3) Install a 9V battery (Alkaline or Heavy duty type) and
then reinstate the cover.
