UT361/UT362 OPERATING MANUAL

Overview

Model UT361 and UT362 are an anemoscopes with high accurate sensitive resistance
(NTC) as testing point. For fan axis, it uses a high durable ruby shaft in order to
provide the accurate and stable measurement. It also comes with 8 digits chip to
conduct the digital mode and double display (VEL + Temperature, Flow + Area)
Model UT361 and UT362 come with the real time wind speed measurement, including
m/s, km/h, ft/min, MPH, KNOT, CFM, CMM as measuring units. In addition, it can
provide maximum value, minimum value, average value record, Centigrade temperature
and Fahrenheit temperature.
For data storage record, the maximum is 2,044 records capability. In sync, it can
provide auto switch down and continuity use functions.
Model UT362 can work with the computer to conduct the real time wind speed, data
transmitting storage and analysis as well as printing purpose.
This Operating Manual covers information on safety and cautions. Please read the
relevant information carefully and observe all the Warnings and Notes strictly.

but bear in mind Warning do not use it in opposite. A screw can fix on it.
(Note: UNI-T will not provide this screw to the customer, the customer need to buy it
separately)

5. Wait for 2 seconds to obtain a more precise reading during the connection
between wind speed measurement and wind source.

6. Obtain a more precise reading; you should move the anemoscope on at least
20 angle degrees in order to get more accuracy.

7. When the measurement of wind speed and wind temperature in parallel, the
secondary display show wind temperature value.

8. Press " / " (button 6) to conduct temperature unit selection, namely,
