Operating Instructions

Function selection

1. Turn on the meter by pressing the Power Button. To turn the meter off, hold the Power Button for over 2 seconds.

2. The meter has 2 measuring functions to choose from: Air velocity/ Temp or Type K/J Thermometer.

When the meter is on, press and hold the Function Button. The display will ash “Air”, for Air velocity/Temperature measurement, and “tP” for Type K/J Thermometer measurement. Release the Function Button to choose the displayed function.

Air velocity/Temperature measurement

When the Telescopic Probe is not in use, slide the Sensor Cover over the Sensor Head. Before using the Telescopic Probe, slide the Sensor Cover down. Be sure to not touch the sensor with your ngers or with any tools, as this may cause damage or incorrect readings.

1. When the meter is off, plug the Telescopic Probe into the Probe Input Socket, then power on the meter by pressing the Power Button.

2. Select the “Air” function (see Function Select).

3. Hold the Probe Handle and face the mark on the sensor head towards the direction that needs to face against the airow. The top part of the Display will show the air velocity, and the lower part of the Display will show the air temperature value.

Changing the Air velocity unit

To change the Air velocity unit, press and hold the Unit Button. The display will ash the units m/S, Km/h, mph, Knot, & FPM. Release the Unit Button to select the displayed unit. The select unit will be saved as the default.

Type K/J Thermometer measurement

Select the “tP” function (see Function Select). Plug the optional Type K or J Thermocouple Probe into the Type K/J

Probe Input Socket. Be sure the Telescopic Probe is not plugged in.

The screen will display a “K”, meaning it is congured for a Type K ther-

mometer probe. The measured temperature will now be displayed on the display screen. To change the meter to accept a Type J Probe, please see the Advanced Settings section.

Data Hold

While taking a measurement, press the Hold Button once and the measured value will hold on the screen, and a HOLD symbol will appear. Press the Hold Button once again will release the data hold function.

Data Record (Max., Min. reading)

The data record function records the maximum and minimum readings. Press the REC Button once to start the Data Record function and a “REC” symbol will appear on the display. With the “REC” symbol on the display:

1. Press the REC Button once, and a ”REC. MAX.” symbol along with the maximum value will appear on the display. To delete the maximum value, press the Hold Button once and the display will show a “REC.” symbol only and execute the memory function continuously.

2. Press the REC Button again, and a “REC. MIN.” symbol along with the minimum value will appear on the display. To delete the minimum value, press the Hold Button once, and the display will show a “REC.” symbol only and execute the memory function continuously.

3. To exit the memory record function, press the REC button for 2 seconds. The display will revert to the current reading.

Backlight ON/OFF

After powering the meter ON, the LCD Backlight will turn on automatically. While taking measurements, press the Backlight Button and the LCD Backlight will turn off. Press the Backlight Button once again to turn the LCD Backlight back ON.

Datalogger

Preparation Before Executing the Datalogger Function:

1. Insert the optional SD card into the SD card socket.

2. Before you use an SD card with this meter for the rst time, it is recommend to format the SD card. See Advanced Settings section of this manual for instructions.

3. If this is the rst time the meter is used you need to adjust the clock. See Advanced Settings section of this manual for instructions.

4. Now you need to set the decimal format. The numerical data structure downloaded to the SD card is defaulted used the “.” as the decimal, for example “20.6” “1000.53”. But in certain countries the “,” is used as the decimal point, for example “20,6” “1000,53”. See Advanced Settings section of this manual for instructions on how to change the Decimal Character.

Auto Datalogger (Set sampling time ≥1 second)

1. Start Datalogging; press the REC Button, and the “REC” symbol will appear on the LCD screen, then press the Logger Button, the “REC” symbol will ash while the measuring data and time information is being saved in memory. To set the sampling time, and to toggle the beeper sound on or off, refer to the Advanced Settings section of this manual.

2. Pause the Datalogging; while Datalogging, if press the Logger Button once. While paused, the “REC” symbol will stop ashing. Press the Logger Button again to resume Datalogging, and the “REC” symbol will begin to ash again.

3. Stop Datalogging; while the Datalogger function is paused, press the REC Button for 2 seconds. The “REC” symbol will disappear indicating the Datalogging function has stopped.

Manual Datalogger (Set sampling time = 0 seconds)

1. Set sampling time is to 0 second; Press the REC Button, and the “REC” symbol will appear on the LCD screen. Press the Logger Button, and the “REC” symbol will ash once and one Beep will sound, at the same time the measuring data along the time information will be saved in memory. The lower Display will show the Position (record) number, which is saved as well.

2. To Change the Position Number; press the Down Button and the lower position number will ash on the display. Press the Up or Down Buttons to set the Position Number (1 to 99) to help identify the measurement location. The lower Display will show P x (x = 1 to 99). After the position number is selected, press the Enter Button to conrm.

Stop Datalogging; press the REC Button for 2 seconds, and the “REC”

symbol will disappear indicating the Datalogging function has stopped.

Checking the Time

During normal functions (not Datalogging), press the Time Check Button and the lower LCD display will show the Year, Month/Date, Hour/Minute.

Check Sampling Time Information

During normal functions (not Datalogging), press the Sampling Button and the lower LCD display will show the Sampling Time Information.

SD Card Data Structure

1. The rst time the SD card is used in the meter, the SD card will generate a folder: AHA01

2. The rst time you use the Datalogger, in the folder AHA01, a new le name AHA01001.XLS will be created. The Datalogger will use this le until the Data has reached to 30,000 rows. The meter will then will generate a new le with a subsequent number, for example AHA01002.XLS.

3. The folder AHA01 can hold 99.XLS les. When that number has been reached, the meter will then will generate a new folder with a subsequent number, for example AHA02. Max number of AHA-folders is 10.

Data Transfer from SD card to Computer (EXCEL Software)

1. After Datalogging, remove the SD card from the SD card slot.

2. Plug in the SD card into the Computer’s SD card slot or insert the SD card into the optional SD card adapter and connect to your Computer. Turn your computer on and a folder will appear on your desktop representing you SD card.

3. Open “Microsoft EXCEL”. Download the EXCEL les from the SD Card to the computer by opening up the SD folder and selecting the desired EXCEL les, and drag-and-drop them onto your Computer. Open the les with EXCEL (File – Open).

4. The EXCEL le will have the following column headers in this order: Place (Position Number), Date (Year/Month/Day), Time (in 24h clock), Value, and Unit.
