# Connected transducers

In the Transducers category of the Edit STbench page, the brakes, the static cells and the external transducers connected to the STbench are listed.

Tapping one of the listed transducers, the Channel page opens, where the transducer parameters are shown. These parameters are read from the transducer and it is not possible to modify them.

If the Trace simulation field of a brake is populated with the message "Advanced pressure setting required", please contact Atlas Copco Service Personnel.

A transducer is highlighted with a red colored bar if it has been overloaded or the calibration has expired.

If an overloaded transducer is select to run a test, a warning message is displayed to inform the operator about the status of the transducer.

When a transducer is used for the first time, an information message is displayed to inform the operator that the first usage date is set to the current date.
Select Yes to set the first usage date to the current date.
Select No not to set the date. If this option is selected, at the next transducer use, the message will be displayed again.

If the transducer calibration is expired, an Information message is displayed to inform the operator that the transducer must be calibrated. It is anyway possible to use the transducer for testing.
