CAUTION!
If more than one reference tare value is programmed (with corresponding minimum sample weight mass) then
the indicated value automatically moves to a range corresponding to the weight of the tared container. At the
same time the required minimum mass is changed.
15.9. COOPERATION WITH TITRATORS
In order to provide correct cooperation with Titrators, go to settings of standard printout content and
set <Mass value for a titrator> parameter to <Yes> parameter. With this, other variables for the
printout are turned off.
With <Yes> parameter on, a respective pictogram is displayed in the top bar of a home screen. The
pictogram informs on special format of mass printout, permissible by TITRATORS.

AMBIENT CONDITIONS - VIBRATIONS
Vibrations are a major cause of errors. Since the vibrations spread in all directions, the
vibrations analysers and meters must carry out measurement in three axes concurrently.
Ambient conditions module implemented in RADWAG balances of 4Y series features such
option.
Analytical balances are precise weighing instruments therefore even insignificant oscillations
influence their operation. Humans are most often unable to sense vibrations. In order to
detect them, it is necessary to use special equipment. Vibrations sensor, along with a
module that analyses the influence of the vibrations onto the measurement, informs the user
in a real time on the possibility of occurrence of error caused by high-frequency vibrations.
Usually the vibrations are dampened with use of anti-vibration tables. Signalling device, i.e.
ambient conditions module equipped with a vibrations sensor, is used to support the process
of vibrations dampening. Such device comes standard with each 4Y series balance. With
use of the said signalling device it is possible to evaluate workstation conditions and if
necessary to find more convenient place of use. It is often impossible to find a place where
no vibrations occur, however the signalling device allows the operator to determine when
and where to expect vibrations of the lowest-frequency.
Due to the following 3 factors: specified values of free vibrations, resolution, and permissible
weighing instrument errors, the analysis must be carried out with regard to the right effective
value (rms value) and bandwidth. Such analysis is performed on each 4Y series balance in a
real time.
When it comes to a module applied in RADWAG-manufactured balances, the filters pass
frequencies to which balances are sensitive. In case of balances, effective value (rms value)
measured from 3 axes and for a particular time interval is given, such value provides
information on amplitude and history of disturbances.
