Battery Warning, Installation and Replacement

1. When the low battery icon appears in the display the batteries are weak and
should be replaced. However, in-spec. measurement may still be made for several
hours after the low battery indicator appears before the instrument reads inaccurately.

2. To replace or install batteries, remove the Philips head screw that secures the rear
battery cover and lift off the cover.

3. Replace the six (6) „AAA‟ batteries (use alkaline heavy duty type), observing polarity

4. Replace and secure the cover.

Datalogging

1. Open the left side door and insert an SD card

Notes:

 The SD card should be at least 1GB in capacity
 Do not use memory cards formatted by other meters or cameras. Use the SD

card formatting procedure under the advanced features section of this manual
to correctly format the card

 The internal clock must be set to the correct time See the advanced features

section of this manual to set the clock

 The default data structure uses a decimal point “.” as the numeric decimal

indicator. See the advanced features section to change this to a comma “,”

 If the SD memory card is not installed, “EMPTY” will appear in the display
 Displayed error messages:

The memory card is full or there is a problem with the card

The battery is low and datalogging is disabled

The SD card is not inserted

2. Press the LOGGER button for >2 seconds to begin logging. “DATALOGGER” will
appear in the display and the meter will beep each time the data is recorded (if the
beeper is enabled).

3. To stop datalogging, press the LOGGER button for >2 seconds. “DATALOGGER” will
change to “DATA” and the meter will count down through the recorded data.

Note: To protect data, do not remove the memory card without properly ending the

record function.

Time/Date/Sample Rate Check

Press and Hold the TIME button for >2 seconds and the display will cycle through the date,
time and sample rate information.

SD Card Data Structure

1. When the SD card if first inserted into the datalogger the folder HBA01 is created.

2. The first datalogging session will then create a file HBA 01001.xls. All data will be
saved to this file until the number of columns reaches 30,000.

3. After 30,000 columns, a new file (HBA01002.xls) is created. This is repeated every
30,000 columns until HBA01099.XLS. At this point a new folder, HBA02 is created
and the process is repeated; HBA10 is the final folder.

Transferring Data to a PC

1. Remove the memory card from the datalogger and plug it into the SD card slot on the
PC.

2. Launch Excel® and open the data file on the memory card from within the
spreadsheet program. The file will appear similar to the one shown below.
