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 environments.
•
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 or the plastic of the outside shell.
•
If a hazardous material is spilt 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 with
the appropriate gauge wire for the current of the instrument. If there are
any questions, call an Authorized Service Center for more information.
• Before using any cleaning or decontamination method except those rec-
ommended by Hart, users should check with an Authorized Service Cen-
ter to be sure that the proposed method will not damage the equipment.
• If the instrument is used in a manner not in accordance with the equip-
ment design, the operation of the thermometer may be impaired or safety
hazards may arise.
• DC Battery Pack Option: Due to the self-discharge characteristics of the
sealed lead-acid battery, it is imperative that the battery be charged after
6–9 months of storage. Otherwise, permanent loss of capacity might oc-
cur as a result of sulfation.
