MEASURING PROCEDURE
Air Velocity Measurement
1) Power on the instrument by pressing the “ Power 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 “Air Flow 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.
Temperature Measurement (Thermocouple)
1) Power on the instrument by pressing the “Power 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) 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.
The temperature difference between thermocouple probe and thermometer will
●
cause an inaccurate measuring result. Therefore, for the best measuring and
accuracy performance, whenever change a probe or plug a new probe, thermal
equivalent between probe plug and meter’s 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.
Humidity & Ambient Temperature Measurement
1) Power on the instrument by pressing the “Power 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.
Light Measurement
1) Power on the instrument by pressing the “Power 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/Fc Button” (3-5, Fig. 1) to select measuring unit “Lux” or “Fc”.
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.
OTHER FUNCTIONS
Hold Function
Whenever press the “Hold Button (3-2, .Fig. 1)” will freeze the current reading value
with a “HOLD” symbol on the display.
Data Record Function
1) The Data Record function records & displays the maximum and minimum
reading values. Start the Data Record function by pressing the “Max./Min.
Button “(3-3, Fig. 1) once. There will be a “REC” symbol on the display.
2) With the REC symbol on the display:
(a) Press the “ Max./Min, Button” (3-3, Fig. 1) once and the Max symbol along
with the maximum value will appear on the display.
(b) Press the “Max./Min. Button” again, the “Min” symbol along with the
minimum value will appear on the display.
(c) To exit the memory record function, press the “Max./Min. 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.
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.
BATTERY REPLACEMENT
1) When the LCD display shows “ ” symbol, it is necessary to replace the battery.
However measurement 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.
