Preparation

Inserting the batteries (see also chapter 9)

• Insert batteries into the battery compartment by first loosening the screw (3-10) and removing the battery compartment cover (3-9).
• Insert the 6 x AAA batteries into the compartment. Pay attention to the correct polarity.
• Place the battery cover back on and secure it with the screw.

The display (3-1) now shows the relative humidity, temperature, and CO2 content. The data are measured by the sensor (3-6).
Note: In chapter 8.6, you can see how to change the temperature unit (°C and °F).

Data logger

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 the 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 a 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.

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.

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.

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.

Data backup from SD card to PC

1. After you have saved data from the meter to the SD card, remove the memory card from its compartment (3-13).
2. Insert the SD card into the reader of your computer.
3. Turn on the computer and start Microsoft Excel. Now you can open the files on the memory card. Excel then allows further processing (e. g .creating graphics) of the data.

Settings

While the data logger function is NOT activated in the tester, press the SET key (3-5) for more than 2 seconds. This takes you to the setting menu and you can navigate through the menu with each further press of the SET key.
Sd F. Format SD card
dAtE… Setting date/time (year/month/day/hour/minute/second)
SP-t… Setting the recording interval
bEEP.. Setting the beeper (ON or OFF)
dEC… Setting the decimal point format (dot or comma)
G-CSF… Setting the temperature unit (°C or °F)
rS232… Setting the RS-232 interface (ON or OFF)
High… Setting the height above sea level in meters
high… Setting the height above sea level in feet
Note: If you do not press any key for 5 seconds, the device automatically exits the setting menu.

SD card format

1. If the display shows “Sd F”, you can use the key (3-3) and the key (3-4) to select “yES” or “no”, where “yES” means to format the memory card and “no” means not to format the memory card.
2. If you have selected “yES”, you must confirm this with the Enter key (3-2). The display then shows “yES Enter”. You must confirm this again with the Enter key (32). The SD card is now formatted and all existing data on the card is deleted.

Setting the time

1. When the display shows “dAtE”, you can set the value with the key (3-3) and the key (3-4) (starting with the year setting). When you have set the value, press the enter key (3-2). Now you can move to the next value. The sequence then is month,
   day, hour, minute, second.
   Note: The value to be set flashes.

2. When you have set all the values and confirmed with the Enter key (3-2), all the settings are saved. Now you automatically enter the menu “SP-t” to set the recording interval.

Note: The date and time always run in the meter. Therefore, you only need to make the setting once, unless you replace the batteries.

Setting the recording interval

1. If the display shows “SP-t”, you can set the value with the key (3-3) and the key (3-4). The sequence is:
   5 seconds, 10 seconds, 30 seconds, 60 seconds, 120 seconds, 300 seconds, 600 seconds, and Auto.

2. After you have selected the desired interval, confirm this with the Enter key (3-2).
   Note: “Auto” means that a data record is always saved if the temperature or humidity changes by ±1 °C or ±1 % RH.

Setting the beeper

1. When the display shows “bEEP”, you can use the key (3-3) and the key (3-4) to select “yES” or “no”, where “yES” means that the beeper is ON and each time a value is stored, an acoustic signal sounds; “no” means that the beeper is OFF.
2. You can confirm and save your settings with the Enter key (3-2).

Setting the decimal point

The decimal point can be formatted as “dot” or “comma”. Since in the USA the decimal point is a “dot” (e. g. 523.25) and in Europe, the decimal point is usually a “comma” (e. g. 523,25), the abbreviations in the display are “USA” for “dot” and “EURO” for “comma”.

1. If the display shows “dEC”, you can select “USA” or “EURO” with the key (3-3) and the key (3-4).
2. You can confirm and save your settings with the Enter key (3-2).
