(ii) Cautions for stopping device operation
• If operation will be stopped for a long period of time, remove the process fluid from inside
the connecting pipes and the pressure-receiving part of the device. The process fluid might,
for example, adhere to the surface of the diaphragm and impede measurement when
operation resumes.
• Leave the equalizer valve open. If it is left closed, output of other than zero can occur when the
power is turned on to restart operation.
