Maintenance
The calibration instrument has been designed with the utmost care. Ease of op-
eration 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.
• It is important to keep the well of the calibrator clean and clear of any for-
eign matter. DO NOT use fluid to clean out the well.
• The dry-well calibrator should be handled with care. Avoid knocking or
dropping the calibrator.
• DO NOT slam the probe stems into the well. This type of action can
cause a shock to the sensor.
• 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 a Hart Scientific Authorized Service Center for more
information.
• Before using any cleaning or decontamination method except those rec-
ommended by Hart, users should check with a Hart Scientific Authorized
Service Center 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 dry-well may be impaired or safety haz-
ards may arise.
