HOT WIRE ANEMOMETER OPERATION
1. Insert the PROBE PLUG (3-14, g. 1) into the socket on top of
the unit labeled INPUT (3-11, g. 1).
2. Turn the meter on by switching the POWER BUTTON (3-2,
g. 1) to the right.

3. Select the desired temperature by pressing the °C/°F BUT-
TON (3-4, g. 1).
4. Select the desired air velocity unit by pressing the UNIT
BUTTON (3-8, g. 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 g 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, g. 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 ngers, 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, g. 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, g. 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, g. 1) while a measurement is being taken
to hold the displayed value. The LCD 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, g. 1) to recall the last minimum
and maximum readings. When the REC symbol appears on
the display, press the RECALL BUTTON (3-6, g 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.
PC SERIAL INTERFACE
This unit features computer output. A COMPUTER OUTPUT
SOCKET (3-10, g. 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).
Data is displayed in a 16 digit stream: D15 through D0. Each digit
indicates the following:
D0 end word
Dl to D4 Upper Display Reading, D1=LSD, D4=MSD
D5 to D8 Lower Display Reading, D5=LSD, D8=MSD
D9 Decimal Point (DP) for Upper Display: 0= no DP,
1= 1 DP, 2=2 DP, 3=3 DP
D10 Decimal Point (DP) for Lower Display: 0= no DP,
1=1 DP, 2=2 DP, 3=3 DP
D11/D12 Annunciator for Upper Display: 00= No Symbol,
01= °C, 02= °F, 03= %, 04= % RH, 05= % PH,
06= %O2 07= mg/L, 08= m/s, 09= knots, 10= Km/h
11= Ft/min, 12= mph, 13= uS, 14=mS, 15= Lux,
16= Ft-cd, 17=dB, 18=mV
D13 Annunciator for lower display: 0= No symbol,
1= °C, 2= °F
D14 Reading Polarity for the display:
0= both upper and lower displays are “+“,
1= upper is “-” and lower is ”+”
2= upper is “+“ and lower is “-”
3= both upper and lower displays are “-”.
D15 Start word
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
difculties. Replacing the batteries with new fresh batteries will
solve most difculties.

Bonus Free Disk This demonstration disk shows the data
acquisition capabilities of this digital product when connected
to a computer. See Cat No. 4136 below to order complete Data
Acquisition System.
Cat. No. 4136 Data Acquisition System Accessory Powerful
and easy to use computer data capture/data logging program
works with Traceable® Instruments with computer output. Records
interval readings from 1 to 10,000 seconds; displays minimum/
maximum readings; and utilizes an alarm mode that permits the
user to be notied visually, audibly, and by email when an alarm is
triggered. Data is stored to a le that can be printed in any report
or spreadsheet format. Networking server/client capability allows
the captured data to be monitored on a remote workstation and/
