• Generating a PDF-File
As soon as the logger is connected to a USB-slot, a PDF file with all recorded data in chart and
an overview of alarms is generated automatically. During PDF generation “USB PDF” appears
on the display, green and red led light indicator, when the PDF file is ready “PDF” disappear and
remaining “USB” on the display.
Depending on the number of stored measurements, generating the PDF-le might take
up to 30 seconds.
As soon as the logger is reprogrammed, the PDF file on the logger will be deleted.

Remark:
CR2450 battery performance is optimal in room temperature. Battery life cycle will reduce at
low temperature (-18
o
C). If the device is to be used to record in extremely low temperature, it
is advised to take measures to reduce power consumption to prolong operation time. An option
includes:
• Choose battery that is designed to operate at low temperature
• Disable LED to reduce power consumption
• Set longer sample interval, 5 minutes for example
