ThermoWorks 9135-156 HART SCIENTIFIC 3-POINT IR CALIBRATOR - Manual (Page 23)

10 Maintenance
• This calibration instrument has been designed for a minimum of required
maintenance as long as it is handled with proper care. Please regard the
following:
• Avoid operating the instrument in an oily, wet, dirty, or dusty environ-
ment. If the outside of the instrument becomes soiled, it may be wiped
clean with a damp cloth and mild detergent. DO NOT use harsh chemi-
cals on the surface which may damage the paint.
• It is very important to keep the IR target clean. Avoid allowing any ob-
jects to contact the surface of the IR target that may contaminate or
scratch it. DO NOT use fluid to clean the IR target. Dust can be blown off
with clean air. When not in use it is advisable to store the calibrator in a
clean covered container.
• The test well must be kept clean and dry. Dirt, oil, or objects stuck in the
well can affect the safety and operation of the 9135 and especially affect
the ability to calibrate the instrument in the future. DO NOT attempt to
insert fluid, grease, or any objects other than clean thermometers into the
well. DO NOT use fluid to clean out the well.
• The calibrator should be handled with care. Avoid knocking, bumping, or
dropping the calibrator. Due to the size and portability of the 9135, it is
vulnerable to being shocked and dropped as it is carried around. It might
be inadvertently dragged off a table top while in use. This can cause per-
manent damage to the instrument and loss of accuracy.
• 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 immediately.
• 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
instrument.
• 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.
• The 9135 calibrator is calibrated at the factory for optimum performance.
Field adjustment to the instrument should not be attempted. If the unit is
suspected to be out of calibration or in need of repair, please contact the
factory for assistance. The unit should be recalibrated at the factory
yearly. Never attempt to modify the instrument.
