3.3Transducer Block
The TRANSDUCER block is a custom block containing parameters that support the enhanced level transmitter. It contains the Jupiter probe configuration, diagnostics, and calibration data, and outputs level with status information.
The TRANSDUCER block parameters are grouped in a useful configuration. There are both

The Transducer Block Mode will automatically be changed to “Out of Service” when the local interface (keypad) is used to change a parameter online.
3.3.1Transducer Block Parameters
The first six parameters in the TRANSDUCER block are the universal parameters discussed in section 3.1.1. The universal parameters are followed by these additional required parameters:
UPDATE_EVT (Update Event): an alert generated by a write to the static data in the TRANSDUCER block.
Another important parameter found later in the TRANS- DUCER block list is DEVICE_STATUS, which displays the status of the device. If more than one message exists, then the messages are displayed in priority order. Refer to Section 5.1.2, Status Messages.
If DEVICE_STATUS indicates a problem, refer to Section 5.1.1, Troubleshooting (those parameters which are shaded are

3.3.2Password Parameters
To change a parameter at the local user interface, a value matching the user password must be entered (Default=1). If the user password is entered, the instrument is in the user mode. After 5 minutes with no keypad activity, the entered password expires.
Factory password is for use by trained factory personnel only.
From the network, the instrument always behaves as if it is in the user mode by default. In other words, it is not neces- sary to enter the user password in order to write parameters from the network.
