Millipore Spectroquant Multy Operating Manual page 250

Important:
Please check whether programmes are running on your
computer that use or monitor the COM ports. These include
e.g. programmes that log the online time, the MSN Messenger
programme, chat programmes, and similar. These programmes
must be completely deactivated during the update process,
since otherwise the HexLoad programme may report
"Communication timed out..." and the update cannot be
executed.
Executing the update
Disconnect the mains supply. Open the battery compartment
and remove the batteries. Beneath the battery compartment
is an opening in which two slide-action switches can be seen.
Slide both switches in the direction of the back of the unit
(terminal jacks for PC and mains adapter).
Connect the colorimeter to the free serial port (COMx) of the
PC using the data-transfer cable. Reconnect the mains supply,
but do not switch the unit on again for the time being.
Double-click on the HexLoad symbol in the folder to start the
HexLoad programme (see figure).
