OGGING
The advanced SD card logging function lets you record all data into
SD card per your preset sampling rate. The sampling rate can be 1
min to 720 mins(12 hours).
Once a new logging is started, a file name will be auto created. The
file name is given per the start date and time. For example:
if the logging starts at 2010/08/28 16:58, the fine name will be given
as 08281658.txt
The maximum file size is 30000 records. Once the file size is bigger
than 30000 records, a new file will be created, and the file name will
be generated.

This product is compatible with FAT16 & FAT32 format SD card.
Suggest maximum SD card capacity is 8GB SD or 4GB SDHC
card.
Before loading or unloading the SD card into meter, please following
below suggestion:
1. The data loss caused by the damaged SD card is not in the product
warranty. Please make sure your SD card can function well before
running a logging.
2. This product is compatible with FAT16 & FAT32. No NTFS formats.
3. Check the available SD card capacity before logging. This meter
will show “FULL” if the capacity is not enough for logging.
4. This meter is designed to use SD or SDHC cards only.
5. This instrument has not been extensively tested by MMX
and SDHC which capacity is over 8GB, so we do not
recommend using it.

6.We don’t warranty that all brands SD card is compatible with
this meter. Suggest running a short-term logging to ensure your
SD card is working on this logger before official recording.
7. Please don’t add extra label on SD card in case the label is stuck
on the SD card slot.

SD CARD LOGGING SETUP
Always power off the meter before loading and unloading the SD
card. Run a short-term logging to ensure the SD card works well on
meter.
Following below steps to start logging.
1. Power off the meter and load the SD card.
Power on the meter, “Sd” flashes on the
right-bottom of the LCD every 5 seconds.
2. Setup the date and time. Please see page 6
3. Setup the sampling rate. Please see page 11
4. The datalogging can be powered by battery however the battery
lifetime is short. For example: While sample rate is 1 min and
using 1GB SD card, the battery lifetime is 1 month only.
Suggest using adaptor for long-term logging. While in a black-out,
the logging will stop and will not be reverted even the electric
is back.
5. If possible, use both battery and adaptor. While in a black-out,
the logging can be continued by using battery.
NOTE:
1. When receiving the meter, one SD card is inserted in the
meter already for initial functional testing.

SD CARD LOGGING START/ STOP
After finishing the sampling rate setting, press “SET” key more than
5 seconds to activate the logging. “ON REC” will appear on LCD
and start to record data into SD card.
1. The “ON REC” will appear on LCD for 2~10
seconds, depended on the SD card capacity.
2. While starting logging, “REC” appears on
LCD every 5 seconds.
3. Power off the meter will terminate the logging.
Power on the meter again will not activate the
logging again.
4. While logging, unload the SD
card will stop logging.

The dew point temperature is the temperature at which the air can
no longer hold all of its water vapor and some of the water vapor
must condense into liquid water. Condensation of water vapor
