Information:

Please maintain the specified torque so that the max. tensile strength

remains.
6. Enter new probe length and if necessary the new probe type and

then carry out a fresh adjustment (see "

Setup procedure, Carry

ing out min. adjustment - Carrying out max. adjustment

").

9.7 Software update

The following components are required to update the instrument

software:

•

Instrument

•

Voltage supply

•

Interface adapter VEGACONNECT

•

PC with PACTware

•

Current instrument software as file

You can find the current instrument software as well as detailed

information on the procedure under "www.vega.com/downloads" and

Software

Caution:

Instruments with approvals can be bound to certain software versions.

Therefore make sure that the approval is still effective after a software

update is carried out.
