Maintenance
• The calibration instrument has been designed with the utmost care. Ease
of operation and simplicity of maintenance have been a central theme in
the product development. Therefore, with proper care the instrument
should require very little maintenance. Avoid operating the instrument in
an oily, wet, dirty, or dusty environment.
• If the outside of the instrument becomes soiled, it may be wiped clean
with a damp cloth and mild detergent. Do not use harsh chemicals on the
surface which may damage the paint.
• Be sure that the well of the furnace is kept clean and clear of any foreign
matter. DO NOT use fluids to clean out the well.
• If a hazardous material is split on or inside the equipment, the user is re-
sponsible for taking the appropriate decontamination steps as outlined by
the national safety council with respect to the material.
• If the mains supply cord becomes damaged, replace it with a cord of the
appropriate gauge wire for the current of the instrument. If there are any
questions, call Hart Scientific Customer Service for more information.
• Before using any cleaning or decontamination method except those rec-
ommended by Hart, users should check with Hart Scientific Customer
Service to be sure that the proposed method will not damage the equip-
ment.
• If the instrument is used in a manner not in accordance with the equip-
ment design, the operation of the furnace may be impaired or safety haz-
ards may arise.
• The over-temperature cutout should be checked every 6 months to see that
it is working properly.
