Step 5.5.7 & 5.5.8

5.5.7 Place the probe in front of

the outlet so that the

sensor’s cover is facing the

outlet

. Press ENTER,

"WAIT" will flash.

No need to move probe at

this time, the VA500A is

waiting until the sensors

stabilize with the new

TEMP. and HUM. readings

(about 90 seconds) then

“START AVERAGE" will

flash (Fig. 17)

5.5.8 Measure for one minute

(Fig.14 step 5) making

sure to move the probe

over the complete area of

the grill (Ref. Step 5.4.6)

Aim at getting an average

reading from all available

openings. At the end of

one minute the unit will

beep and the LCD screen

will display the results in

Btu/h.(Fig.18)

5.5.9 To repeat this measure-

ment, the return air and

grill size are already in

memory, simply press

ENTER and repeat

sections 5.5.3 -5.5.8

above.
