Perform a measurement

Turn on the device by pressing on “On/Off/Esc”. The device displays its name “LV130”.
Put the probe to the required location. The device displays the velocity and temperature measurements

Freeze the measurement

During the 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 once 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 since the last questioning at the bottom of the screen.
Press once 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 exit the hold function. The device returns 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 and “AVG” blinks.
Press on “OK” to stop the average 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 measurement display.

Display and measure the air flow

It’s possible to display and measure the airflow in place of velocity. The device is on and displays the velocity and temperature measurement.

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. “CIRC” blinks on screen, press on “Select” to make appear “K 25 85” then “RECT”.
Press on “OK” to validate. If “RECT” or “CIRC” are selected, the measuring unit of the duct type 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 value 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 return to the display of airflow and velocity measurements.
If the type of selected duct is rectangular: “LENGT” 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 value 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 the airflow and temperature measurements.

If “K 25 85” is selected: the device returns to the measurements display.

The length, the width and the section diameter are adjustable from 1 to 3000 mm
