°C/°F - ESC key

 

 
The measured temperature value is used to compensate the wind speed measurement.  When the 
temperature probe is connected, the key changes the unit of measurement from degrees Celsius to 
Fahrenheit.  
If the probe is not present, the compensation temperature must be entered manually: to manually 
change the value shown in the display lower line, press °C/°F once. The temperature indicated starts 
blinking. While the display is blinking, it is possible to change the compensation temperature in the 
-200…+600°C range using the arrows (

 and 

). Confirm using ENTER. The display stops 

blinking, and that temperature is used for compensation. 
If the temperature probe is not present, to change the unit of measurement between °C and °F, it is 
necessary to press 

twice 

the °C/°F key. 

 
 

 

REL/

 key

 

In measurement mode, it displays the difference between the current value and that measured on 
pressing the key for both measurements - main and secondary. The 

REL

 message appears on the 

display; press the key again to return to the current measurement. The REL function is not applied 
to manual temperature: if the thermocouple probe is not present, on pressing REL the error 
indication ERR appears. 
When used in the menu, it decreases the current variable value. 
 
 

 

MENU Key

 

 
The first menu item is accessed by initially pressing on the MENU key; press ENTER to go to the 
following items. To modify the item displayed, use the arrow keys (

 and 

). The current value is 

confirmed by pressing the ENTER key and the display moves on to the next parameter. If pressing 
ESC the setting is cancelled. 
To exit the menu, press the MENU key at any time. 
 
The menu items are listed in this order: 

1)

 

Differential pressure resetting

: the most sensitive pressure sensors are affected by an error 

linked to their position. By rotating the instrument from the horizontal to the vertical 
position there is a variation in the measurement of a few Pascals. This is the reason the reset 
command was designed for the differential value: leave the inputs of each probe open so that 
they detect the same pressure and place the instrument in the position that will be used to 
perform the measurement. When entering the menu, the "PRES_REL_TO_ZERO 
ENTR_TO_MENU" message appears: press REL to reset the difference or press ENTER to 
access other menu items. To guarantee the accuracy of maximum results, do not modify the 
instrument's position compared to that used during the resetting. 

2)

 

Pressure probe bottom scale:

 the pressure sensor bottom scale is presented.  

3)

 

SECT m

2

 - SECT inch

2

: this parameter defines a duct's 

section area 

for flow rate 

calculation. It is expressed in m

2

 or inch

2

. To change the unit of measurement, press UNIT.
