OPTIONAL ACCESSORY OPERATION
Operation of the Data Logger (DLOG301)
The DLOG301 option provides the customer with a means of logging data electronically
for viewing at a later date. Logged variables are Temperature, Humidity, CO
2
and Light
Intensity (but only if the chamber is equipped with those features.) All data is time-
stamped with year, month, day of the month, hour, minute, 24 hour time (ISO 8601
format). This data is stored internally in the chamber in non-volatile memory.
Note: The date and time are logged within the actual file name. The file’s “Date
modified” field is not maintained and therefore may not reflect the actual date and
time the file was created.
Data is logged every 5 minutes (provided the chamber is on); more than 10 years of
data can be stored in memory. If the internal memory fills up, new data overwrites the
oldest data.
File name format is “DATE START YYYY-MM-DDTHH-MM_.csv” (hours in 24 hour time)
When the chamber is on, the chamber’s history data is being stored even when a flash
drive is
not inserted in the USB port. This data may be retrieved anytime using the
provided USB flash drive.
Continuous writing to the flash drive necessitates a high quality
industrial grade device. Use only the flash drive provided by
Caron (or equivalent: single level cell memory, wear leveling
algorithms, error correcting code).
