Chapter 7 Operation
Beginning Operation
When the zero adjustment described previously is completed, the device is ready for use.
Consequently, measured values can be checked.
y
Checking Measured Values
y
Check the measured value using the communicator.
y
After checking of the measured value, disconnect the communication cable, tighten the
cover of the junction box, and change the process to its normal operation.
y
If the output value or display value of the analog signal does not correspond to the pro-
cess conditions, take the following measures. If the problem does not improved even
after countermeasures have been taken, try the troubleshooting procedures.
y
Check the range
y
Re-calibrate
y
If the output or display of the measured value is not stable, adjust the damping time
constant.
Handling Precautions
y
If the damping time constant is set to 0 s, this device will pick up minute
fluctuations in the liquid level, thus showing an unstable output. It is
recommended that the damping time constant be set to 1 s or longer.
y
After Checking the Measured Value
After checking the measured value, make sure that the case and cover of this device are
closed securely. If they are not closed securely, rainwater may enter the device, damaging
the internal terminals and electronics module.
Stopping Device Operation
y
Stopping the Operation of This Device
