5.4.2 Log in and lock out (compliant instruments only)
The Log In and Lock Out menu allows the user to define the Log In requirement and toggle the Lock Out feature
within Running Viscosity Test (see Figure 5-14).
The Log In check box controls the Log In requirement. When Log In is checked, the DVNext will require a User ID
and Password prior to allowing any activity. The Log In screen is presented on power up or when the User Icon
is selected from the Home Menu. The user must select their user ID from the drop-down list and then enter their
password. The Log In requirement is removed when the check box is unchecked.
Note: Administrator default password is admin.
The Allow Manual Lock Out check box found in the Lock Out Options sub menu controls the Running Viscosity Test
Lock Out function. This function is only available when User Login is required. When Allow Lock Out is checked, the
user may lock the DVNext during a test. The Lock Out is set by pressing the Lock Icon found in the Navigation Bar
of Running Viscosity Test. Any touch of the screen during the Lock Out will show the user a Log In screen. No action
can be taken on the DVNext until the proper password is entered. Only the User ID that was in effect when the Lock
Out was initiated can unlock the DVNext. The test will continue to collect data during the Lock Out.
The Allow Timed Lock Out check box found in the Lock Out Options sub menu controls the automatic feature of
Lock Out. Set the Timed Lock Out time value from 1 – 99 minutes. The DVNext will Lock automatically (without
touching the Lock Icon) after the test is initiated (press Run) when the screen has not been touched for the time
