B. CONTINUOUS MOVING AVERAGE

1. Turn the power ON .

2. Place sensor in front of air flow

source.

3. Press MN/MX record key once.

An "AVG" in the lower left corner

of the display confirms the meter

is in the continuous moving average

measurement mode. The display

will update once per second.

(See Fig.3)

The meter has the ability to display

continuous moving average for up to

two(2) hours.

1. Press the ON/OFF button and turn

meter on. Meter will show full display

when first powered on in 5 seconds.

(See Fig.1)

2. Unit is ready for use when LCD display

shows "vel" at upper left corner and

To clear the current MIN/MAX average

readings, turn off the power or press

and hold MN/MX key until unit beeps

twice, then release.

1. Turn the meter on and position the

vane at the first point to be measured.

soon as the first measurement is

completed press the HOLD key,(you

will hear a single beep), and release.

The display will show HOLD above

number represents the point that is

being recorded.(See Fig.5)

Hold anucinator and point at the

lower corner will be disappeared in

one second.

3. Once all measurements have been

recorded press SEL/AVG key.

The unit will display the average air

velocity reading and number of points

measured. ( See Fig.5-1) as an

example of stored 8 points shows

average air velocity measurement.

Repeat this process until all desired

points have been measured and

recorded, A maximum of 8 points may

be recorded at one time.
