Control Company 4331 ANEMOMETER/THERMOMETER - Manual

points have been measured and recorded. A
maximum of 8 points may be recorded at one
time.
3. Once all measurements have been recorded,
press the AVERAGE MULTIPOINT button. The
unit will display the average air velocity
reading and number of points measured.
Auto Power Off
The unit will turn off automatically after 15
minutes of non-use to save the battery. This
action is preceded by 3 beeps.
Non-Sleep Mode (Bypass Auto Power Off)
Power the unit off. Press ON and HOLD buttons
at the same time. Release the ON button only. An
“n” indicator appears on display. Release HOLD
button. The unit will remain on and in Bypass
Auto Power Off mode until OFF button is pressed.
OPERATIONAL DIFFICULTIES
1. If the display is flashing or there is no display
when switched on, change the battery (see
Battery Replacement section).
2. If the display indicates an “E6” reading, the
related circuits or parts of thermistor have
failed (see Warranty, Service, or Recalibration
section).
3. If the unit’s fan will not turn this indicates that
the sensor fan is damaged (see Warranty,
Service, or Recalibration section).
4. If the unit does not function properly for any
reason, other than those listed above, replace
the battery with a new high-quality battery (see
Battery Replacement section). Low battery
power can occasionally cause any number of
apparent operational difficulties. Replacing the
battery with a new fresh battery will solve most
difficulties.
BATTERY REPLACEMENT
Erratic readings, a faint display, a flashing display
or no display are all indicators that the battery
must be replaced. To replace the battery, remove
the screw from the lower panel on the back of the
unit. Lift the panel out and remove the exhausted
battery and replace with a new 9-volt alkaline
battery and replace the cover. Replacement
battery Cat. No. 1112.

OPERATION
Measurement Default (Imperial /Metric)
1. Make sure the unit is OFF by pressing the
ON-OFF/RESET button.
2. Press and hold the AVERAGE button. Then press
the ON/OFF button once to turn the unit on. When
the “ft/m, m/s” and “ ° C, ° F” indicators appear,
release the AVERAGE button.
3. To select metric units, press the HOLD button. “m/s
and “ ° C” will show on the display. To select
imperial units, press the AVERAGE button. “ft/m”
and “ ° F” will appear on display.
4. Press the MIN/MAX REC button. A “5” will show on
the display. Press the HOLD button. A pre-setting
of “1200” or “2400” baud will display.
5. Press the MIN/MAX REC button again. The “5”
indicator will display again. Press the HOLD
button; the unit will revert to the normal measure-
ment display. The default setting is now complete.
6. Press the HOLD button to measure the current air
velocity and temperature with the selected units.
The “HOLD” indicator should disappear.
NOTE: Not pressing the HOLD button retains the
display in freeze mode.
Air Velocity Measurements
ft/min, mph or knots - Set the unit to Imperial
measures. Each press of the “SEL: MIL/H KNOT”
button will change the reading to ft/min, mil/h or knots.
Km/hr or m/s or knots - Set the unit to metric
measures. Each press of the “SEL: MIL/H KNOT”
button will change the reading to Km/hr, m/s or knots.
Typical Air Velocity and Temperature Measurement
Place the meter in an air stream. Make sure that the air
stream and the sensor are aligned. Allow three
seconds for the reading to stabilize.
Measuring Air Velocity (Single Point)
1. Press ON/OFF button to turn on unit. The display
will appear after 5 seconds.
2. Unit is ready for use when the “vel” indicator
appears at upper left hand corner and “ ° C” or “ ° F”
appears at the lower right hand corner.
Continuous Moving Average
The unit can display a continuous moving average for
up to 2 hours.
1. Power the unit ON.
2. Place the unit in an airflow.
3. Press MIN/MAX REC SINGLE-POINT button once.
“REC” and “AVG” appearing in the lower left corner
of the display confirms that the meter is in
continuous moving average measurement mode.
The display will update once per second.
Minimum/Maximum/Average Reading
On a Single Point
1. Power the unit ON.
2. Place the unit in an airflow.
3. Press the MIN/MAX REC SINGLE-POINT button.
The unit will begin to record the readings. The
meter displays the average air velocity by default.
Each press of the MIN/MAX button cycles the
display through the following readings:
• No indicator - Real-time readings
• REC - Unit is recording the reading
• AVG REC - Unit is recording the average velocity
• MIN REC - Unit is recording minimum velocity
• MAX REC - Unit is recording maximum velocity
4. Press the HOLD button to store the readings before
moving the meter away from an airflow source.
5. Press ON/OFF RESET to turn the meter OFF.
6. To clear the current MIN/MAX average readings,
turn off the power or press and hold MIN/MAX
button until the unit beeps twice, then release.
Air Velocity Average for Multiple Points
1. Turn the meter on and place the unit in an airflow 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 MIN/MAX button, (a single beep will be
heard) and release (the secondary display will show
a digit). This number represents the point that is
being recorded. Repeat this process until all desired
