Thanks Martyn
The scope works now.
Would appreciate to be able to use it also as a 4 channal data logger.
Shouldn't I be able to use the PicoLog?

Trying to install software for 4424.
Installer asks for "Device". In drop-down list there is no 4000 series.
Checked for larest software version, however, the report is that the version on the CD is the latest.
What do I put as "Device" to continue installation?
