Operating Instructions

For the best results when using your instrument,

make sure the airstream and the sensor are aligned

as shown (±20 degrees maximum) and wait 3

seconds for the reading to stabilize.

Single Point Air Velocity (fpm)

1. Press the Power button to turn the meter on.

The meter will show the full display for the

initial 5 seconds.

2. The instrument is ready for use when

the LCD display shows "vel" in the upper

left corner and temperature in the lower

right corner.

Continuous Moving Average

The meter has the ability to display continuous moving

average for up to two (2) hours.

1. Turn the power ON.

2. Place the sensor in front of the air

flow source.

3. Press the Max. / Min. button. An "AVG" and

"REC" will appear in the lower left corner of

the display to confirm the meter is in continuous moving average

measurement mode. The display will update every few seconds.

MIN/MAX/AVG Reading on a Single Point

1. Turn the power ON.

2. Place the sensor in front of the air flow source.

3. Press the Max. / Min. button. The unit will begin to record the

readings. The meter displays the average velocity by default. Each

press of the Max. / Min. button cycles the display through:

• Real-time readings

• MIN velocity

• MAX velocity

• AVG velocity

4. To revert to normal measurement mode or clear the current MIN,

MAX and AVG readings, turn OFF the meter, then turn it ON again

or press and hold the Max. / Min. button until the meter beeps

twice, then release.

5. Note: Feet Per Minute (fpm) readings can be converted to Cubic

Feet per Minute (cfm) readings by following the instructions below:

• Press the Hold button to store the readings before moving the

meter away from an airflow source

• Press the Mode button to enter area setting. After setting the

area, press the Mode button again to convert fpm into cfm.

Multipoint Air Velocity Average

1. Turn the meter ON and position the vane at

the first point to be measured. As soon as

the first measurement is completed press

the Hold button, (you will hear a single

beep), and release. The display will show

Hold above the reading.

2. Press the Max. / Min. button, (you will hear

a single beep), and release, (the display will

show a digit 1-8). This number represents

the point number which has been recorded.

3. Repeat the above procedure until all desired

points have been measured and recorded.

A maximum of 8 points may be recorded at

one time.

4. Once all the measurements have been

recorded, press the Average button to view

the average air velocity reading and the

number of points which are recorded.

5. Press the Hold button to revert to normal measurement mode.

6. To clear multi-point average memory, press and hold the Average

button until the unit beeps twice, then release.

Auto Power OFF

The unit will turn off automatically after 20 minutes to save the battery.

This will be preceded by 3 beeps.

To disable auto power off:

1. Turn the power OFF.

2. Press the power button and the Hold

buttonat the same time and then release

the Power button only. When an "n"

Default unit setting (Imperial or Metric)

The default measuring units can be changed by following the steps below.

The unit should be turned off before starting.

1. Press and hold the Average button, then

press the Power button once to turn the

unit ON. When the LCD displays "ft/m",

"ms", "°C" and "°F", release the Average

button.

2. To choose the metric units, press the Hold button. The LCD

should display "m/s" and "°C".

To choose the imperial units, press the Average button. The LCD

should display "ft/m" and "°F".

3. Press the Max. / Min. button. The LCD should display "S".

Then press the Hold button. The LCD will display 2400 or 1200

(pre-setting).

4. Press the Max. / Min. button again, the LCD

should display "S" again. Then press the

Hold button, the LCD will revert to a normal

measurement display. The default setting is

now completed.

RS232 Output

1. Following Step 3 of Default unit setting, you

will see a "2400" (default) number on the

screen. The 2400 is the default setting of

Baud Rate for RS232 output. You can

change the setting to "1200" by pressing

the Hold button and to "2400" by pressing

the Average button.

2. Please remember to save your changes by pressing the

Max. / Min. button. An "S" will display on the LCD. Press the

Hold button to confirm and save the changed value. The meter

will return to air velocity mode automatically.

3. Plug the earphone jack of the cable VZRS232M into the RS232

socket on the meter and connect the 9-pin D-sub to the comput-

er's COM1 or COM2. Press ON to start measurement.

Measuring ft/m, MPH, Knot (km/hour)

In imperial, press SEL:.MPH. KNOT, the reading will change from ft/m,

mil/h, knot in turns.

In metric, press SEL:.MPH. KNOT, the reading will change from m/s ,

km/h, knot in turns.

Direct Single Point Air Flow Measure (cfm)

Air Velocity measurement is calculated by multiplying the air velocity

readings by the free area dimensions. You must first determine the free

area of the air source before entering it into the meter.

1. Turn the power ON.

2. Press the Mode button once. The LCD will

display "AREA" and "1.111" will appear.

The first digit will flash.

3. Press the Hold button to increase

4. Press the Average button to advance to next number. Follow Step

3 and repeat to input the free area size.

5. Press the Mode button once all digits have been entered. The

word "FLOW" will appear. The meter is now ready to measure air

flow (cfm).

Multipoint Air Flow Average (cfm)

1. Follow Step 1 to 4 of Multipoint Air Velocity Average.

2. Press the Mode button once and confirm the correct free area set-

ting is locked into the instrument. (If the free area setting must be

adjusted, make the necessary changes now.)

3. If the free area setting is correct, press the Mode button again to

enter air flow mode.

4. Unit will now display the average air flow reading and the number

of points measured.

MIN/MAX/AVG for Single Point Air Volume

1. Turn the power ON, select the mode as FLOW and the place the

sensor in front of the air flow source.

2. Press the Max. / Min. button, the unit will begin to record the read-

ing. Press the Max. / Min. button to read the real time value, the
