Device Operation (cont’d)
Manual Start
The LyoTemp can be started using the magnetic wand
provided (in the IFC300) to touch the start/mark switch, if
it is first programmed for a Manual Start in the MadgeTech
4 Software. Once the device is programmed the status will
change to Waiting for Manual Start. To begin recording,
touch the wand to the start/mark switch, the green
LED (OK) will blink 5 times followed by the yellow LED
(WARN) and the red LED (ALARM), indicating the device is
recording. The logger must be manually stopped through
the MadgeTech 4 Software.
Marking Feature
