Rerange with a pressure input source and the local zero and
span buttons (option D4)
Reranging using the local zero and span adjustments (see Figure 3-11 on page 57) and a
pressure source is a way of reranging the transmitter when specific 4 and 20 mA (1 and 5 Vdc)
points are not known and a communicator is not available.
Note
When you set the 4 mA (1 Vdc) point the span is maintained; when you set the 20 mA (5 Vdc)
point the span changes. If you set the lower range point to a value that causes the upper range
point to exceed the sensor limit, the upper range point is automatically set to the sensor limit,
and the span is adjusted accordingly.
To rerange the transmitter using the span and zero buttons, perform the following procedure:
1. Loosen the screw holding the certifications label on the top of the transmitter housing.
Slide the label to expose the zero and span buttons. See Figure 3-11.
2. Apply the desired 4 mA (1 Vdc) pressure value to the transmitter. Push and hold the
zero adjustment button for at least two seconds but no longer than ten seconds.
3. Apply the desired 20 mA (5 Vdc) pressure value to the transmitter. Push and hold the
span adjustment button for at least two seconds but no longer than ten seconds.
