6.4 How to prepare Measurement
6.4.1
Taking a reference signal
For processing a signal emitted by an ultrasonic sensor, an appropriate reference signal is
required. QuintSonic 7 autonomously checks the validity of the existing reference signal. If the
reference signal is invalid, you will be asked to take a new reference signal (see screenshot
below). If the reference signal is valid, you can directly proceed on measurement. The reference
signal is retained in the non-volatile memory to ensure it will be available even after the gauge has
been switched off.
A reference signal may become invalid due to one or several of the following incidents:
You have switched the measuring range.
The current temperature varies too much from the temperature during the acquisition of the
reference signal.
Generally, the acquisition of a reference signal is only required if such message appears. In order
to ensure optimum precision of the system or if very difficult measuring tasks are involved (e.g.
very thin coatings, low echo amplitudes), it is recommended to refresh the reference signal prior to
measurement (see section 9 “Tips and tricks”).
It is also recommended to take a reference signal prior to calibration (see section 5 “Calibration“).
For taking a reference signal please proceed as follows:
Option 1: via the main menu
Press Main Menu-function key.
Select “Active Batch” from the list.
Press OK to confirm.
The “Batch” menu is active.
