HOT WIRE ANEMOMETER OPERATION
1.
Insert the PROBE PLUG (3-14, fig. 1) into the socket on top of the unit labeled
INPUT (3-11, fig. 1).
2. Turn the meter on by switching the POWER BUTTON (3-2, fig. 1) to the right.
3. Select the desired temperature by pressing the °C/°F BUTTON (3-4, fig. 1).
4. Select the desired air velocity unit by pressing the UNIT BUTTON (3-8, fig. 1).
Each press of the button will show a different unit of measurement on the
display (m/s, km/h, ft/min, Knot, mile/h).
5. Slide the sensor cover to the end of the SENSOR HEAD (3-12 fig 1). See Figure
2. This allows the sensor head to be protected from the environment for a more
accurate zero reading.
Figure 2
6. Push the ZERO BUTTON (3-7, fig. 1). The display
should read 0,0.
7. Slide the sensor cover towards the probe handle to
expose the sensor head. Caution!! Do not allow
fingers, tools or any other object to come in
contact with the air velocity sensor. Any contact
may permanently damage the sensor and the meter will not work properly.
8. Adjust the TELESCOPE PROBE (3-13, fig. 1) to the desired length.
9. Note the mark located at the top of the SENSOR HEAD. This mark should be
pointed towards the source of wind being measured. When this mark is placed
towards the wind source, the upper display will show the air velocity value. The
lower display shows the temperature.
10. To hold a measurement on the display, press and hold the HOLD BUTTON (3-3,
fig. 1) while a measurement is being taken. The LCD display will show DH in the
upper left portion of the display to indicate that the value is a “held” value. To
cancel the data hold feature, simply press the HOLD BUTTON a second time.
11. To record a measurement, press and hold the RECORD BUTTON (3-5, fig. 1)
while a measurement is being taken to hold the displayed value. The LCD
display will show REC in the lower left portion of the display to indicate that the
value is being recorded. To deactivate the record function, press the RECORD
BUTTON again.
MEMORY RECALL OPERATION
Use the RECALL BUTTON (3-6, fig. 1) to recall the last minimum and maximum
readings. When the REC symbol appears on the display, press the RECALL BUTTON
(3-6, fig 1) once. The maximum recorded value will be displayed. II letters “Max” will
also appear on indicating that this is the maximum or highest reading. A second press
of the RECALL BUTTON will display the minimum reading. The letters “Min” will also
appear indicating that this is the minimum or lower reading. Note: The Data Record
function must be in use to utilize the Memory recall features. Once the RECORD
BUTTON has been pressed a second time to deactivate the data record function, the
minimum and maximum values are no longer stored.
COMPUTER INTERFACE
This unit features computer output. A COMPUTER OUTPUT SOCKET (3-10, fig. 1) is
located on the top of the unit. To utilize this feature, connect the unit to a PC with the
Data Acquisition Accessory. (see Accessories section).
LOW BATTERY
If the letters “LBT” appear on the left corner of the display, ti indicates the batteries are
low and need to be replaced. To replace the batteries, slide the battery cover located
on the back of the unit away from the unit. Remove the old batteries and replace them
with six new 1.5V AAA alkaline batteries. Use alkaline batteries, NOT regular or heavy
duty batteries. Place the batteries in the proper direction as indicated by the diagram in
the battery compartment. Incorrectly installed batteries may damage electronics.
Replace battery cover.
ALL OPERATIONAL DIFFICULTIES
If this anemometer does not function properly for any reason, please replace the
batteries with six new 1.5V AAA alkaline batteries (see Low Battery section, above).
Low battery power can occasionally cause any number of “apparent” operational
difficulties. Replacing the batteries with new fresh batteries will solve most difficulties.
