SuperUser Mode
The SuperUser mode offers the possibility of an advanced analysis of the signal and the measured values as well as the
definition of additional parameters adapted to the measuring point, in order to achieve better measuring values or during
experimental work. Features of the SuperUser mode are:
• Defaults will not be observed.
• There are no plausibility checks when parameters are being entered.
• There is no check whether the entered parameters are within the limits determined by the laws of physics and technical
data.
• The cut-off flow is not active.
• A value for the number of sound paths has to be entered.
• Some menu items that are not visible in the normal the normal mode are displayed.
14.1
Activation/Deactivation
Enter HotCode
071049
.
It is displayed that the SuperUser mode is activated. Press ENTER. The main menu will be
displayed.
Enter HotCode
071049
again to deactivate the SuperUser mode.
It is displayed that the SuperUser mode is deactivated. Press ENTER. The main menu will
be displayed.
14.2
Defining the Flow Parameters
In the SuperUser mode, it is possible to define some flow parameters (profile bounds, correction of the flow velocity) for
the specific application or measuring point.
Select
Special Funct.\SYSTEM settings\Measuring\Calibration
.
Press ENTER.
14.2.1 Profile Bounds
Select
user
if the profile bounds are to be defined. If
factory
is selected, the default pro-
file bounds will be used and the menu item
Calibration
will be displayed (see section
14.2.2).
Press ENTER.
Enter the max. Reynolds number at which the flow is laminar. The entered number will be
rounded to the hundreds. Enter
0
(zero) to use the default value 1 000.
Press ENTER.
Enter the min. Reynolds number at which the flow is turbulent. The entered number will be
rounded to the hundreds. Enter
0
(zero) to use the default value 3 000.
Press ENTER.
A request is displayed if an additional correction of the flow velocity is to be defined. Select
on
to define the correction data,
off
to work without correction of the flow velocity and re-
turn to the menu item
SYSTEM settings
.
For the definition of the correction of the flow velocity see section 14.2.2.
Attention!
Some of the defined parameters are still active after the deactivation of the SuperUser mode.
Attention!
The SuperUser mode is intended for experienced users with advanced application knowledge. The
parameters can affect the normal measuring mode and lead to wrong measuring values or to a fail-
ure of the measurement when a new measuring point is set up.
