Chapter 3 Starting and Stopping this Device
(2) Starting Operation
After zero adjustment as described in the previous section, the device can be operated. Proceed to
check its measurements.
(i) Checking measured values
• Using the communicator, check the measured values.
• After checking, disconnect the communication cable, attach the device's case cover, and switch
the process to normal operation.
• If the analog signal output and the displayed values do not match the process conditions,
- Check the setting range
- Check of the location at which the flange is attached to the process
- Recalibrate
If there is still no improvement, carry out the troubleshooting in Chapter 4.
• If the measurement output and display do not stabilize, refer to Chapter 4 and adjust the damping
time constant.
(ii) Cautions following checking of measured values
After checking the measured values, confirm that the device's case cover is securely closed. If it is
not securely closed, rainwater and the like can enter the device and cause damage to the terminals,
electronics modules, etc., located inside.
(3) Stopping Operation
(i) Stopping operation of the device
Turn off the power to the device.
(ii) Cautions for stopping device operation
When stopping operation for a long period of time, remove the flange portions of the device, clean
the diaphragm with a soft brush and some solvent, and store it. When doing so, be careful not to
deform or scratch the diaphragm. In addition, remove the process fluid from inside the connecting
pipes and the device's pressure-receiving part as well. The process fluid might, for example, adhere
to the surface of the diaphragm and impede measurement when operation resumes.
