       The device displays its name  LV110 ,  LV111  or  LV117 .
    Put the probe to the required location.
       The device displays the velocity and temperature measurement.

FREEZE THE MEASUREMENT
During a measurement :
    Press once on  Hold/min/max .
        Hold  appears on screen and the measurement is frozen.
    Press on On/Off/Esc  to exit the hold function.
       The device returns to the measurement display.

DISPLAY THE MINIMUM AND THE MAXIMUM
Once the measurement is frozen :
   Press on Hold/min/max .
  The device displays the maximum value of velocity or airflow measured since the last questioning at the top of the screen and the minimum value of velocity or airflow measured since the last questioning at the bottom of the screen.
   Press again on  Hold/min/max .

The device displays the maximum value of temperature measured since the last questioning at the top of the screen and the minimum value of temperature measured since the last questioning at the bottom of the screen.
  Press on On/Off/Esc to return to the measurements display.

PERFORM AN AVERAGE IN VELOCITY
The device is on and displays the measurement.
  Press on OK .  START  displays on screen.
  Press on  OK ,the average calculation is launched,  END  displays on screen,  AVG  blinks.
  Press on  OK  to stop the calculation, the average displays.
  Press on OK  to display the maximum and minimum values measured during the calculation of this average.
  Press on  On/Off/Esc  to exit the average function and return to the measurements display.

DISPLAY AND MEASURE THE AIRFLOW
It is possible to display and to measure the airflow in place of the velocity. The device is on and displays the velocity and temperature measurements.
  Press on  Select .
       MODE  blinks on screen.
  Press on  OK .
       VELO  blinks at the bottom of the screen.
  Press on  Select  to select the FLOW mode then press on  OK  to validate.
      Depending on the device type,  CIRC ,  K 25 85 ,  CONE  or  RECT  blinks at the bottom of the screen.
  Press on  Select  to select rectangular  RECT ,  CIRC ,  K 25 85  (LV110) or CONE  (LV111) for a measurement with an airflow cone then press on  OK .

If  RECT  or  CIRC  is selected, the measuring unit of the type of duct displays.
  Press on  Select  to select the unit : mm or inch then press on  OK to validate.

If the type of selected duct is circular : DIAM displays and the first digit blinks. Press on Select to select its value then press on OK to validate. Perform the same procedure to select the values of the following digits (to return to the previous digit press on On/Off/Esc ). When the last digit is adjusted, press on  OK to validate. The device returns to the display of airflow and temperature measurements.
If the type of selected duct is rectangular :  LENGT displays on screen and the first digit blinks. Press on  Select  to select its value then press on  OK  to validate. Perform the same procedure to select the values of following digits (to return to the previous digit press on On/Off/Esc ). When the last digit is adjusted, press on  OK .  WIDTH  to adjust the width displays on screen, perform the same procedure to select the digits value, when the last digit is adjusted, press on  OK to validate. The device returns to the display of airflow and temperature measurements.
  If  K 25 85  is selected (LV110): the device returns to the measurements display.
  If  CONE  is selected (LV111): CONE  displays on screen and the cone type blinks : K35, K75, K120, K150. Press on  Select  to select the type of cone, then press on  OK  to validate. The device returns to the display of airflow and temperature measurements.
