Cooperation With Titrators; Ambient Conditions - Vibrations - RADWAG UYA 4Y.PLUS Ultra-Microbalances Manuel De L'utilisateur

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> value. With this, other variables for the
printout are turned off.

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. In
case of the module that is in-built into balances manufactured by RADWAG, the filters analyse those
frequencies to which the weighing devices 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.
Radwag has designed analysis method and selected permissible vibrations thresholds respectively to
make signalling device operation both effective and convenient (not troublesome). Balance screen
displays balance-registered vibrations level in percent.
Vibrations threshold cannot be changed, however the operator can modify settings in a way ensuring
that alerts are displayed in the most convenient way, depending on the needs. By default the set
value is 100%.
