Operation of the Data Logger
The data logger feature provides the customer with a means of logging data
electronically for viewing at a later date. Logged variables are Temperature, Humidity,
H
2
O
2
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).
