This is a very useful feature.
|
Print a quick graph of the logger record just by clicking on the Print
Graph button.
The hardcopy record
can act as a document that can be certified with a hand signature.
For example this could be used in HACCP programs or vaccine storage certification,
or food quality assurance.

Good
news: Because of the high quality of modern inkjet and laser printers, the
graph has very high sharpness and can clearly display the 0.5C degree resolution
of the logger. |
