5.4.7 The LCD will display the

measured Air Volume in

CFM (cubic feet per minute)

(Fig. 10).

5.4.8 To repeat this measurement

or IF YOU WISH TO MEA-

SURE ADDITIONAL

OPENINGS, press ENTER

and repeat steps 5.4.2-5.4.7.

Measure each opening as

previously described in

order to obtain an overall

average reading. At the

completion of each test, the

sum of ALL measurements

can be displayed by pressing

the

Ç button.

*When moving probe along

the grill’s borders (A,D) keep

the probe halfway out of the

grill.

Note: Aim at getting an average

reading from all available open-

ings. (see next step)

5.5 Measuring Capacity

IMPORTANT NOTE:

Before you begin to measure capacity,

press the MODE button until you reach the HUMIDITY

mode. Put the probe in front of the inlet air (or ambient

room humidity) so that the sensor’s cover is facing AWAY

FROM THE INLET GRILL and wait until the humidity meas-

urement stabilizes (this also allows the “TEMP” measure-

ment to stabilize). DO NOT place the probe at the output

grill because it will take a long time (10 minutes) to return to

normal room temperature and humidity conditions!
