For that reason, larger measuring error may occur if a cold sensor is placed on a warm measuring
object or vice versa. Whenever possible, it is recommended, prior to measurement, to provide for a
temperature adjustment of sensor and measuring object.
Good results can be achieved by storing sensor and measuring object in the same room for a
period of about 15 or better 30 minutes prior to measurement so that sensor and measuring object
can adapt to the ambient temperature accordingly.
In the ideal case, measurement should take place under the same temperature conditions under
which the determination of sound velocity has been carried out. In such case, the different
temperature coefficients in the individual layers will no longer have an effect on measurement.
6.3 Settings to make prior to measurement
Before taking readings, it is required to carry out some settings via Main Menu / Active Batch.
QuintSoinc 7 store readings in batches. First create a batch and store in under a name in the
database. The name you have assigned to your batch is shown on the measuring screen. New
readings will be added and stored to the currently active batch. If you switch the gauge off, the
name of the last batch you have used will be memorized so that you can continue in this batch
even after a switch off.

Using the Direct Mode
For quick, rough or trial measurements, QuintSonic offers a permanent batch named “Direct
mode“. In this mode, no storage or processing of data or parameter settings are made. For quick
access to this mode, select “Database” from the “Main Menu”. The “Direct Mode” is placed on top
of the highest directory level. In this mode, you can proceed immediately on the trial
measurements. There is no need to make any entries such as name of batch or other. The
parameter values of the last action in this mode are active. You can either continue in this setting
or change parameters if required.
Use this batch for quick measurement action and if data processing or storage of parameters
settings are not required.
For using the “Direct Mode” go to the database and select “Direct Mode” (see also section
11.2.3.5).
