1. FEATURES
* One meter can accept two probes :
Hot wire anemometer probe
*
Combination of hot wire and standard thermistor,
deliver rapid and precise measurements even at low
air velocity value.
* Slim hot wire probe, ideal for grilles & diffusers.
* Air velocity : m/s, Ft/min, Km/h, Knot, Mile/h,
* Air flow ( CFM, CMM ) measurement.
*
Air temperature ( ℃, ℉)
*
Air Temp. used thermistor sensor, fast response time.
* Fast humidity measuring response time.
* Type K, Type J thermocouple thermometer.
* Real time SD memory card Datalogger, it Built-in Clock
and Calendar, real time data recorder , sampling time set
from 1 second to 3600 seconds.
*
Manual datalogger is available ( set the sampling
time to 0 ), during execute the manual datalogger
function, it can set the different position ( location ) No.
( position 1 to position 99 ).
* Innovation and easy operation, computer is not need
to setup extra software, after execute datalogger, just
take away the SD card from the meter and plug in the
SD card into the computer, it can down load the all the
measured value with the time information (
year/month/date/ hour/minute/second ) to the Excel
directly, then user can make the further data or graphic
analysis by themselves.
* SD card capacity : 1 GB to 16 GB.
* LCD with green light backlight, easy reading.
* Can default auto power off or manual power off.
* Data hold, record max. and min. reading.
* Microcomputer circuit, high accuracy.

4. MEASURING PROCEDURE
4-1 Function selection
1) Power on the meter by pressing the " Power button "
( 3-2, Fig. 1 ) > 1.5 seconds continuously.
* After already power on the meter, pressing the
" Power button " > 1.5 seconds continuously will
turn off the meter.
2) The meter can select 6 kind function as :
1. Air velocity/Temp.
2. Air flow ( CFM/USA type, CMM/Euro type )
3. Type K/J Thermometer
Pressing the " Function Button " ( 3-6, Fig. 1 )
continuously ( not release the button ), the Display
will show the following text in sequence :
Air Air velocity/Temp. measurement
AirF
Air flow measurement
tP
Type K/J Thermometer measurement
Until the Display show the desired mode ( Function ),
just release the " Function Button " ( 3-6, Fig. 1 ), the
meter will execute this function with default.

Important information of using the Telescope Probe
*
When the probe is not used, the " Sensor cover "
should slide to the up position.
When the probe is not used, the
" Sensor cover " should slide to the
up position.

Probe Handle
*When begin to use the probe,
a.
Slide the sensor cover to the down position, let the
air velocity sensor to contact the air, refer Fig. 3.
b. Extent the telescope probe to the convenient length
,refer to Fig. 3
air velocity sensor
( do not touch by
fingers or tools )
