What to do if Siemens Transmitter calibration interval has expired?
- CclairepetersenAug 26, 2025
If the calibration interval as defined in Reminder 2 has expired on your Siemens Transmitter, perform calibration.
What to do if Siemens Transmitter calibration interval has expired?
If the calibration interval as defined in Reminder 2 has expired on your Siemens Transmitter, perform calibration.
What to do if Low and High Calibration Points are the same in Siemens Transmitter?
If the Low Calibration Point and High Calibration Point input parameters are the same on your Siemens Transmitter, check the calibration settings of the device and ensure that the settings for the High Calibration Point and Low Calibration Point are different.
What to do if Siemens SITRANS LR560 Transmitter shows material build-up on antenna?
If your Siemens Transmitter display shows material build-up on the antenna, use the air purge feature to clean the antenna or re-locate the device.
What to do if calibration interval defined in REMINDER 1 has expired on Siemens Transmitter?
If the calibration interval as defined in REMINDER 1 (REQUIRED) has expired on your Siemens Transmitter, perform calibration.
What to do if calibration interval has expired on Siemens SITRANS LR560?
If the calibration interval as defined in REMINDER 2 (DEMANDED) has expired on your Siemens Transmitter, perform calibration.
What to do if Fail-safe is activated on Siemens SITRANS LR560?
If Fail-safe is activated on your Siemens Transmitter, it could be due to: * Hardware failure. * Memory failure. * Fail-safe LOE timer expired, possibly due to faulty installation, antenna material buildup, adverse process conditions like foaming, or an invalid calibration range. To address this: * Correct the configuration. * Ensure the installation is correct. * Check for antenna buildup and clean if necessary. * Adjust process conditions to minimize foaming or other adverse conditions. * Correct the calibration range. If the problem continues, or if it's due to hardware or memory failure, contact your local Siemens representative.
What to do when service interval as defined in Maintenance Required Limit has expired on Siemens SITRANS LR560?
Perform service on Siemens Transmitter because the service interval as defined in Maintenance Required Limit has expired.
