Flowmeter Startup

Additionally, if you have the enhanced core processor and you are using ProLink II to zero the flowmeter, you can also restore the prior zero immediately after zeroing (e.g., an “undo” function), as long as you have not closed the Calibration window or disconnected from the transmitter. Once you have closed the Calibration window or disconnected from the transmitter, you can no longer restore the prior zero.

3.5.1Preparing for zero

To prepare for the zero procedure:

1.Apply power to the flowmeter. Allow the flowmeter to warm up for approximately 20 minutes.

2.Run the process fluid through the sensor until the sensor temperature reaches the normal process operating temperature.

3.Close the shutoff valve downstream from the sensor.

4.Ensure that the sensor is completely filled with fluid.

5.Ensure that the process flow has completely stopped.

CAUTION

If fluid is flowing through the sensor, the sensor zero calibration may be inaccurate, resulting in inaccurate process measurement.

To improve the sensor zero calibration and measurement accuracy, ensure that process flow through the sensor has completely stopped.

Before You Begin

Using ProLink II

3.5.2Zero procedure

To zero the transmitter:

•With ProLink II, see Figure 3-3.

•With the zero button, see Figure 3-4. Note the following:

-You cannot change the zero time with the zero button. If you need to change the zero time, you must use ProLink II.

-The zero button is located on the front panel of the transmitter. To press the zero button, use a fine-pointed object that will fit into the opening (0.14 in [3.5 mm]). Hold the button down until the status LED on the front panel begins to flash yellow.
