Enhancement Parameters
P905 TRANSMIT PULSE
Press to supply repeated transmit pulses to the transducer and / or view the
transducer operating frequency (automatically altered by (P004) Transducer) for
the Point Number displayed.
This feature may be used to monitor the transmit pulse with an oscilloscope
connected to the transducer terminals.
values: 10.00 to 60.00
P906 COMMUNICATIONS
Press
to test the Siemens Milltronics proprietary communications circuit.
Before activating this feature, connect terminal block contacts 42 to 45 and 43 to 46.
