UNI-T UT361 Operating Manual

UT361/362
Anemoscopes
Overview
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 micro-
processor 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).
This Operating Manual covers information related to the safe operation of
the Anemoscope. Please read the relevant information carefully and observe
all the Warnings and Notes strictly.
Warning
To avoid electric shock or personal injury, read the "Safety Information"
carefully before using the Anemoscope.

Safety Information
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.
Warning
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
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.
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
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
damage caused by the high temperature.
Do not try to recharge the battery.
