Operating Instructions

Function selection

This meter can have three probes plugged in at the same time: the Hu­midity, CO
three values, but will only display one at a time on the LCD screen.

Display Function
rH Humidity/Temperature
dP Dew point Temperature
_ET Wet bulb Temperature
CO CO/Temperature
O2 O2/Temperature
CO2 CO2/Temperature
The selected measurement function will be saved as the default.

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) Plug in the Humidity, CO

, and either the O2 or the CO Probe into

the meter.

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

3) Press the Function Button to scroll through the measuring
functions:

1) Press the REC Button once, and a ”REC. MAX.” symbol along with

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.

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.

3) Stop Datalogging; press the REC Button for 2 seconds, and the
“REC” symbol will disappear indicating the Datalogging function

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: AQA01

2) The rst time you use the Datalogger, in the folder AQA01, a new
le name AQA01001.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 AQA01002.XLS.

3) The folder AQA01 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 AQA02. Max number of AQA-­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).
