5 Measuring
5.1 Switch between measurement parameters
The anemometer shows 2 different measurement parameters at the same time. By default, these
parameters are air temperature on the lower display and flow velocity on the upper display. To change
the displayed parameters, use the Up and Down buttons.
By pressing Up, you can switch between flow velocity and relative air humidity on the upper display.
When pressing Down, you can switch between air temperature, volume flow, wet bulb temperature and
dew point temperature on the lower display.
5.2 Volume flow measurements
Before measuring the volume flow, you have to enter the dimensions of the cross-sectional area in the
setup menu (see chapter 7.1.2 for more information).
After AREA setting is completed, press the down button to switch the display to air volume flow and the
measured air volume flow will be displayed on the lower LCD.
You can also measure the volume flow with an airflow cone. To do so, just attach one of the optional
cones to the meter. The anemometer detects the cone automatically and shows a cone indication on the
display. After that, the device will calculate the volume flow.
Note: Make sure the airflow cone is well mounted and locked tight.
5.3 Measuring relative humidity
The capacitive humidity sensor is built in the centre of the vane.
Press the Up button to show the relative air humidity on the upper display.
It is also possible to set an offset value. See chapter 7.1.3 for more information.
6 Functions
6.1 Data Hold
In normal measuring mode, press the Hold button to freeze the current reading on the LCD.
A “HOLD”
icon appears on the display. To unfreeze the reading, just press the press the Hold button again.
6.2 MIN/MAX
In normal measuring mode, press and hold the Hold button for 3 seconds. The display now shows the
MIN value, as well as a “MIN” indication.
Press and hold the button again,
to view the MAX value. The display also shows a “MAX” indication.
Press and hold the Hold button once again to return to normal measuring mode.
Note: While viewing the MIN and MAX values, you can use the Up and Down buttons to switch between
the different parameters.
