DATA LOGGING
5.1 - Data logging capacity
The Zen Datalogger is supplied with a
1GB Micro SD card
, which is the default storage location
for logged data. The Micro SD card can hold up to 7.8 million data samples - enough for nearly
15 years' data logging at 1 sample per minute.
If you remove the Micro SD card to download data from it (see 5.5), the Zen will continue
to log data to its onboard memory. The onboard memory capacity is 32MB (31,744 data
samples) - enough for 22 days' data logging at 1 sample per minute.
Logged data which has been temporarily saved to the onboard memory will be automatically
transferred to the Micro SD card as soon as it is inserted again. (This process can take some
time, depending on how much data needs to be transferred. You will not be able to safely
remove the Micro SD card again [as in 5.5] until the transfer has completed.)
NOTE
Please use the supplied 1GB Micro SD card.
Commercially available Micro SD cards
with a capacity higher than 1GB are not supported by the Zen Datalogger.
