SERVICE

5.1 GENERAL

The servicing and calibration procedures described in this section should only be performed by qualified technical personnel.

These procedures should not be performed while the Remote Set Regulator is connected to an on-line process. A laboratory setup is recommended for calibration and servicing. If this is not possible, steps should be taken to close down the process or to isolate the Regulator in such a manner that it has no control over the process.

** Warning **

Models intended for operation in hazardous areas require additional precautions. Under no circumstances should the cover be removed while the instrument is powered and operating. If access is required, either the dc power must be turned off, or the environment must be made safe, i.e., non-hazardous. An electrical spark in a hazardous en- vironment could cause fire or an explosion and result in property damage and injury to persons.
