Electric Damping; Fast Measured Value Acquisition (Fast Response Mode) - Siemens 7MF4333 User Manual

On-Line Operation
1. Install and pipe the transmitter. Ventilate or evacuate the transmitter.
•
Ventilate for pressure, differential pressure, flow, and flanged level transmitters.
•
Evacuate for absolute transmitters to <0.1% of the measuring span.
2. In the Online menu, press 3 Device Setup on the HART Communicator.
3. Press 3 Basic Setup in the Device Setup menu.
4. In the Basic Setup menu, press 3 Position Correction. A warning will appear: "Loop should be
removed from automatic control." Press the ABORT or OK softkey as appropriate.
5. A second warning will appear: "This will affect sensor calibration."
6. The message "Apply 0 input [atmospheric pressure] the sensor" will appear. Press ABORT or OK as
appropriate.
7. A "correction successful" message will appear followed by a Loop may be returned to automatic
control message.

6.4.5 Electric Damping

Electric damping can be adjusted within the range of 0 to 100 seconds.
1. Press 3 Device Setup in the Online menu.

6.4.6 Fast Measured Value Acquisition (fast response mode)

This mode is designed exclusively for special applications such as fast acquisition of pressure spikes, such
as a compressor surge. Here, the internal measured value acquisition is accelerated at the cost of accuracy.
There is an increase in low-frequency noise in the measured value. For best accuracy, configure the
transmitter for use at its maximum measuring span.
1. Press 3 Device Setup in the Online menu.
2. Press 4 Detailed Setup in the Device Setup menu.
3. Press 2 Signal Condition in the Detailed Setup menu.
4. Press 6 Measuring Speed in the Signal Condition menu.
5. Use the arrow pushbuttons to select: Fast, Medium, or Slow.
6. Press the ENTER softkey to save the selection and return to the Signal Condition menu.
