permissions assigned to him or her. Refer to section User Accounts (Auditor) to assign
this permission to a user. This field appears only if the Auditor feature is enabled.

Login Timeout
Provides the option to log out an inactive (no key-presses detected) user when a preset
number of minutes have elapsed. This can be set to ‘Off’ for no automatic timeout, or
between 1 and 99 minutes. This field appears only if the Auditor feature is enabled.
Pass Attempts
Specifies whether a user has unlimited attempts of logging in (‘Unlimited’) or only three
attempts before their account is disabled from logging in (‘3’). This field only appears if the
Auditor feature is enabled.
Min Password Len
Specifies the minimum number of characters allowed for a password, between 3 and 9
characters. This field appears only if the Auditor feature is enabled.
Sup Log Disabled
Determines whether the Supervisor level login is permitted (‘No’) or disabled (‘Yes’). It is
recommended that this be set to ‘Yes’ if the Auditor feature is used. This field only appears
if the Auditor feature is enabled.
Passwords Expire
Provides the option to specify the number of days before a password will expire. This can
be set to ‘Off’ for no expiring passwords, or between 1 and 999 days. The expiry counter
is reset when the password is changed. When the password expires, it will not work any
more. The engineer’s password never expires so as not to block all access. This field
appears only if the Auditor feature is enabled.
{uuu} Pass Expires If the Passwords Expire parameter is set to any number (other than ‘Off’), indicating that
passwords will expire after a set number of days, a list of all configured (and enabled)
users is displayed next to the Pass Expires parameter, showing the number of days
remaining before each account’s password will expire. These are read-only and cannot be
altered here. This field appears only if the Auditor feature is enabled, and the Passwords
Expire parameter is set to anything other than ‘Off’.
Default Config
This field appears only if ‘reset’ has been entered as the Engineer Password. Selecting
‘Yes’ Causes the instrument to restart with default configuration (i.e. the instrument ‘cold
starts’). See Note 2 above.
OEM SECURITY
In products that incorporate user wiring, the value of an application may lie more in the user wiring (connecting
the function blocks together) than in the configuration of the instrument's parameters.
OEM Security allows the user to prevent the application from being copied either via comms (by iTools or a third
party comms package) or via the instrument's user interface.
When OEM security is enabled, users are prevented from accessing wiring (for reading or writing) from any
source (comms or user interface), and it is not possible to Load or Save the configuration of the instrument via
iTools or by using the Save/Restore facility (Section 6.1.8).
From firmware version V5.00 onwards OEM Security is enhanced by providing an option, enabled by a new
parameter ‘Instrument.Security.OEMParamLists. This parameter is available only through iTools and allows the
OEM to:-
1. Make all parameters that are read/write in Engineer access level only, read only when the instrument is
OEM locked AND it is in Engineer access level. It is possible for the OEM to select up to 100 parameters
which are to remain read/write in Engineer access level.
