Q: Do all graphs have to be created from one data logger?
A: No. You can create graphs using files from different data
loggers and different data logger models.
Q: I have a version of vLog earlier than version 4.5. What happened to
that Verification process? And why, in Version 4.10 and later, has this
been replaced by the Logger File ID Number?
In Vaisala Veriteq vLog, logger data and graph files can be
generated at different times by different people. Consequently,
there is a need for verification that the logger files used to create
graph files are the right ones. This has been handled in vLog
versions prior to version 4.10 by the verification process that
required a transfer username and password to be entered in
order to verify graphs.
The Logger File ID Number is a more flexible approach that
allows users to compare the printed records they have against
the logger files they are using to create graphs.
However, if you are an existing customer with VL-Series loggers
you can still use usernames and passwords for verification.
Note:
Do not use your Windows username and password,
as you may be required to share the username and

in vLog VL.
To configure the username and password prompting option:
1
Select
Tools | Options
, then choose the

tab.
2
Select the
Prompt for username and password when
transferring samples
checkbox.

. See page 107 for instructions on how to verify a
graph with a username and password.
Q: How can I verify a graph on the screen if I have forgotten my pass-
word?
A: You can’t. Vaisala Veriteq vLog VL software requires the
original password when transferring the data logger in order to
verify the status of the file. This is a security feature for validation
to ensure that the person responsible for transferring the data is
also the person who creates the graph. For vLog 4.10 and later,
the username and password feature is optional and can be
