6.2 Adjustment with the PC

In the following setup and adjustment instruc-
tions you will find information on the following
topics and adjustment points:
• Configuration

- configuration info
- create new measurement loop

• Parameter adjustment 1

- adjustment
- scaling

• Sensor optimisation

- meas. environment
- sound velocity
- echo curve
- false echo storage

• Parameter adjustment 2 (optional)

- linearisation
- parameter adjustment sensor display
- meas. loop data

• Display of measured value
• Simulation
• Select available linearisation curve
• Print configuration and adjustments
• Backup

Note:

Keep in mind that you first have to log in a
sensor in the configuration menu before you
can continue with the parameter setting, and
if necessary, carry out adjustments in the
menu “Sensor optimisation”.

For connection of the PC to VEGASCAN, a
standard RS 232- DTE-DTE (Data Terminal
equipment) interface cable is required. With
the cable, the PC is connected to
VEGASCAN.

Setup

Beside the measured values, the adjust-
ments signals are also transmitted digitally
via the signal supply cable between sensor
and VEGASCAN. The adjustment program
VVO can then communicate with VEGASCAN
and all connected sensors. In chapter "2.6
Configuration of measuring systems“ the
connection of the PC to the different sensor
arrangements is shown.

Before starting the setup:

Do not be confused by the many pictures,
adjustment steps and menus on the following
pages. Just carry out the setup with the PC
step-by-step and you will soon no longer
need the following pages. Whenever you
should adjust or choose something, this is
indicated in the following by a large black
dot, like this:
• Choose …
• Start …
• Click to …
• Connect the standard output of your PC by

the standard RS 232 interlink cable (9-
pole) to VEGASCAN.

• Now switch on the power supply of the

processing system.

By this means, the actions to be carried out
are clearly separated from supplementary
information in the following adjustment in-
structions.

Approx. 1 … 2 minutes after switching on the
supply voltage, the sensors generally show
measured values on the sensor display.

After the adjustment software on the PC has
attained connection to VEGASCAN, you start
with the "Configuration“ of your measuring
system.
