(1)All the accuracies indicated in this technical datasheet were stated in laboratory conditions, and can be guaranteed for measurements carried out in the same conditions, or carried out with calibration compensation.

Once the measurement is frozen:

• Press on "Hold/min/max".

The device displays the maximum value of velocity or airow measured since the last questioning at the top of the

screen and the minimum value of velocity or airow 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.

Display the minimum and the maximum

• Turn on the de device by pressing on "On/Off/Esc".

The device displays its name "LV110", "LV111" or "LV117".

• Put the probe to the required location.

The device displays the velocity and temperature measurement.

Perform a 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.

Freeze the measurement

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.

Perform an average in velocity

It is possible to display and to measure the airow 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 airow 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 rst 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 airow and temperature measurements.

• If the type of selected duct is rectangular: "LENGT" displays on screen and the rst digit blinks.
