Note: When the Auditor feature is enabled, entry of an invalid feature password will result in the
feature codes becoming read-only for a period of 30 minutes. This is to discourage multiple
attempts to guess a feature password. This period cannot be shortened.
Feature2/3 Pass
Comms Pass
Note: 1. It is recommended that only such characters as appear on the user's PC keyboard be used
in the Engineer password. The use of other characters makes it necessary to use 'Escape'
codes (e.g. Alt 0247 for the '÷' sign) when trying to enter configuration mode from iTools, for
example.
Note: 2. Restoring factory default configuration can also be carried out in iTools, using the Engineer
password 'reset' and selecting Default Config to 'Yes'.

Similar to 'Feature Pass' above, but for additional features.
Enables/disables password security for external communications (including via iTools). If
set to 'Enabled', the Engineer level password will be required if an attempt is made to enter
the configuration menus from a remote PC. If set to 'Disabled', then access to
configuration can be gained over a communications link, without a password.
If enabled, then entry to configuration mode via the Instrument Mode (IM) parameter must
be completed within 5 seconds of entering the password, or the attempt will fail.
The configured pass phrase used to enable / disable the OEM security option. This field
is editable whilst the OEM Status is 'Unlocked' and the user has 'Engineer' access.
To lock or unlock the OEM security feature, the user must enter the pass phrase entered
in 'OEM Pass' above. The default pass phrase is 'OEM' (in capitals).
Read only 'Locked' or 'Unlocked' status display.
Determines whether an audit trail is written to the history file (when set to 'Yes'). When
enabled, all configuration parameter changes, operator alarm acknowledgements, and
cloning status changes are recorded in the history. Note that during iTools and USB
cloning, the audit trail is temporarily disabled since, potentially, every parameter could
change. However, the fact that a clone has been loaded will be written to the history by
the audit trail. This field appears only if the Auditor feature is enabled.
When enabled (set to 'Yes'), if a user tries to enter a signable menu or edit a signable
parameter, the signing dialog will appear (see below). For the required action to proceed,
the selected signing user must enter their password and a note (which cannot be blank),
and then set Accept to 'Yes'. If signing is accepted, messages are added to the history
along with the entered note. This field appears only if the Auditor feature is enabled.

When enabled (set to 'Yes'), similar to the Signing parameter above, an additional user
(the authorizer) will need to enter their password to approve the operation. Other than the
built-in Engineer or Supervisor accounts, an authorizer will need to have Authorizing
