6 MAINTENANCE
6.1 Cleaning
Clean the front panel of the instrument with a soft cloth, dampened with soapy water. We recommend to not use
abrasive detergents or detergents that contain solvents, since they could damage the instrument; also, do not splash
water or any other liquid directly on the instrument.
6.2 Repairs
All repairs must be carried out by authorized personnel. Opening the instrument container or tampering with the
controller automatically annuls the warranty. lf necessary, consult the nearest DTI customer assistance.
7 CALIBRATION
All controllers are automatically computer calibrated at the DTI production facilities. lf the indicated temperature
value is not correct, check the connections, as well as the probe cables, especially when different cables are connected
to each other. lf it is not possible to eliminate the failure, then set the value to be added or subtracted in parameter
#19, in order to reach a correct indication of the process variable.
8 ABOUT THE OPERATING INSTRUCTIONS
These operating instructions are to be considered part of our product and are therefore to be kept with proper care
until the product itself is disposed of. The user can directly request new operating instructions from DTI, should those
supplied have been damaged or lost. These operating instructions include the technical state-of-the-art at the
moment the product was sold and, as such, cannot be considered inadequate only because they were successively up-
dated on the basis of new experiences. DTI reserves itself the right to modify product features and/or to up-date the
operating instructions at any time, without giving prior notice and without the obligation to up-date previously issued
versions. The user can request possible up-dates or integrations directly from DTI; he/she may also request further
information about the product and in turn make proposals on how to improve these operating instructions. The
information included in these operating instructions shall serve to illustrate the use of the product as foreseen in the
project, to list its technical features,
to supply information about instrument installation and regulation, to prescribe maintenance procedures, to list
residual risks, etc. Hence DTI assumes no responsibility deriving from the improper use of its products or use by
incompetent personnel, incorrect installation, faulty power supply, serious lack of prescribed maintenance, non-
authorized modifications or interventions, the use of spare parts that are either not original or not specific for this
series of models, not fully complying with the operating instructions, force majeure, etc.
