Warning
To avoid electric shock or personal injury, read the "Safety Information"
carefully before using the Anemoscope.
Unpacking Inspection
Open the package case and take out the Meter. Check the following items
carefully for any missing or damaged part:
In the event you find any missing or damaged item, please contact your dealer
immediately.
In this manual, a Warning identifies conditions and actions that pose hazards
to the user, or may damage the anemoscopes or the equipment under test.
A Note identifies the information that user should pay attention to.
Safety Information
Warning
Before using the anemoscopes inspect the case,do not use the anemoscopes
if it is damaged or the case (or part of the case) is removed. Look for cracks
or missing plastic．
Pay attentions to the insulation around the connections.
To avoid possible electric shock or personal injury and to avoid possible damage
to the anemoscopes or to the equipment under test, adhere to the following rules
Do not touch the vane of the fan and the temperature sensor that are all
sensitive parts of the anemoscope, for it may affect normal operation of the
instrument.
Replace the battery as soon as the battery indicator appears．
If the anemoscope works abnormally, please stop using it and have it serviced
by nearby service center.
Do not use the anemoscopes in an environment of explosives, humidity, inflam
-mables. The performance of the anemoscopes may deteriorate after dampened.
Use the specific authorized replacement part if you need to repair the
anemoscopes
Do not use the anemoscope with the housing or cover opened.
Note the battery " + " and " - "pole when installing the battery.
The following conditions or actions may cause damage to the anemoscope,
please take caution when using the anemoscope.
Select the appropriate wind speed before use, it may avoid overloading
damage to the vane of the anemoscope fan(0~30m/s) under the unknown
scenarios.
Select the temperature meaning in 0 to 40 in order to avoid any fan
damage caused by the high temperature.
Do not try to recharge the battery.

in the memory, it's used to obtain the first recorded data.
Function Key
Short press to record current measured reading; Long press to
read the data in the memory.
Press and hold the button while turning on the anemoscope, all
recorded data in the memory will be cleared; When viewing the
recorded data, it's used to subtract quickly.
It is a functional menu button. Press and Hold it to configure the
anemoscope.
In air flow mode, it's used to move the decimal point randomly
when entering the Area value. START refers to decimal point
after the first input digit, NEXT is to move the decimal point for
next digit.
To set up the Area in air flow mode.

Note:0~9 numeric buttons are used to key in Area value settable within 0.000
~9999 during air flow measurement.
UT361 and UT362 Anemoscopes are designed with built-in high precision
thermistor as air temperature sensor and a highly durable ruby vane ring to
maintain accurate and stable measurements, and also offer 8-digit microprocessor for data processing. The instrument measures real-time air velocity
(m/s, km/h, ft/min, mph, knots), air flow(CFM, CMM) and air temperature( / ).
It also comes with remarkable features: dual display (Vel+Temp, Flow+Temp),
Max/Min/Average, data hold, data storage up to 2044 sets, auto power off,
PC communication (UT362 only).
To switch the units for air

Setting the Anemoscope
Under air velocity and flow modes, press and hold Button 9(MENU) to enter
menu setup. press MENU to access next menu option.
A. USB setup
Press button 8 from USBO USB1. The unit defaults at "USB0 "every time
at power-on status.
B. Auto Power Off
Press button 8 from AP00 AP01 , the setting is saved even after power-off.
The unit defaults at the saved setting when powering on. no need to reset
again.
C. Auto Record Interval
Effective auto recording is settable within 0.5~255s, REC displays on upper
part of LCD, and the lower part shows the set time (0.5~255). Press Button 2
to increment or long press to increment quickly; press Button 8 to decrement
the time or long press to decrement quickly. The setting will be automatically
saved after power off. The unit defaults at the set status and needs no resetting

Measuring Air Velocity (Air Temperature)(See Figure 4)
To carry out anemoscopes, follow the following procedure:
Note: Place the anemoscope in the air with velocity above 10m/s for 1-2min
before making the measurement.
Computer Connectivity (For UT362 only)(See Figure 5)
When the anemoscope (UT362) communicates with PC, use USB cable to
connect the instrument to the USB port of PC, See Figure 5.

Maintenance
B. Replacing The Battery
To avoid false reading, which could read to possible electronic shock or
personal injury, replace the battery as soon as the battery indicator " "
appears.
To replace the battery
1) Turn the anemoscope off and remove all the connections from the input
terminals
2) Turn the anemoscope's front case down
3) Remove the screw from the battery compartment and separate the battery
compartment from the case bottom
4) Take out the old battery and replace with a new 9V battery (6LF22)
5) Rejoin the case bottom and the battery compartment and reinstall the screw.
C. Service And Repairing
The Anemoscope is a highly intelligent and precision instrument and adopts
auto calibration technique. Unless otherwise specified, do not replace all
components randomly to avoid the accuracy bias.
Do not attempt to repair or service
your anemoscope unless you are qualified to do so and have the relevant
calibration, performance test, and service information
A. General Service
1) Periodically wipe the case with a damp cloth and mild detergent. Do not
use abrasives or solvents.
2) Take out the battery when it is not using for a long time.
3) Do not use or store the Meter in a place of humidity, high temperature,
explosive, inflammable and strong magnetic field.
