Measurement:

After connecting the probe and switching on the ALMEMO

device the meas-

ured values will be correctly scaled including their dimension and can be imme-

diately read out in m/s.

When performing measurements in an air duct the safety distances to turbu-

lent points must be observed. To obtain undisturbed measured values the in-

strument ALMEMO

2390-5 or 2690-8 is particularly suitable because it con-

tinuously averages the measured values by the function TIME CONSTANT.

Further measuring functions for averaging and for volume flow measurements

are described in the ALMEMO

Manual (chapt. 3.5.5) or Description on Aver-

aging.
