2 Introduction
The PCE-AQD 10 is a data loggerwhich records and saves the CO2content, air temperature and
relative humidity. The data is stored on an SD card (up to max. 16 GB SDHC). The device is
mainly used for long-term recording in the food sector (refrigerated counters in department stores,
refrigerated transport, warehouses) as well as for measurement and recording indoors (meeting
rooms, offices, etc.)

6 Data logger
6.1 Preparation
a. Insert the SD card (1 GB to 16 GB) into the SD card slot (3-13). Ensure that the
card is oriented correctly.
b. When you use the card for the first time, it must be formatted. Refer to chapter 8.1
for more information.
Note: Please do not use an SD card formatted in another device (e. g digital
camera) In this case, you have to format the SD card again in the data logger. If
there are any problems during formatting, please try to format the card in your PC.
This procedure may solve the problem.
c. Set the time: When you use the meter for the first time, the time must be set. See
chapter 8.2 for more information.
d. Format of decimal point: The format on the SD card uses a "dot" as the decimal
point, e. g. “20.6” or “1000.53”. You can also choose a comma as decimal point,
see chapter 8.5.
e. Information that can appear on the display:
This indicates a problem with the SD card. It is also displayed
when the SD memory card is full. In this case, replace the
memory card.
This indicates that the battery voltage is too low. In this case,
please replace the batteries.
This indicates that there is no memory card in the device.

6.2 Data logger function
Press the logger key (3-2) for more than 2 seconds until the display shows
"DATALOGGER". Now the data logger starts to save measured values.
If you want to switch off the data logger function, you must press the logger key (3-2)
again for more than 2 seconds. The "DATALOGGER" indicator then disappears from the
display.
in chapter 8.3, it is described how to set the recording interval; in chapter 8.4, it is
described how to set the beeper.
Note: Before removing the SD card, make sure that the data logger function is stopped.
Otherwise, you may lose data from the SD card.
6.3 Time information
If you press and hold down the time key (3-3) for more than 2 seconds, the following data
appears in the display: year/month/day, hour/minute/second and the recording interval.
6.4 SD card data structure
1. When you first insert the card into the meter, it generates a folder on the memory
card: HBA01
2. When you start the data logger function for the first time, the meter generates a file
under the HBA01\ folder with the name HBA01001.xls. The data is then saved to
this file. As soon as there are 30,000 data records in this file, a new file is created.
This file then has the name HBA01002.xls.
3. When 99 files are stored in the HBA01 folder, the machine creates a new folder with
the name: HBA02\...
4. This results in the following structure:
HBA01\
HBA01001.xls
HBA01002.xls
.
.
. ...
HBA01099.xls
HBA02\
HBA02001.xls
HBA02002.xls
.
.
. ...
HBA02099.xls
HBAXX\
...
Note: The highest value XX can stand for is 10.
