ThermoWorks 9103 HART SCIENTIFIC FIELD DRY-WELL TEMPERATURE CALIBRATORS - Manual (Page 44)

11 Maintenance
• The 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.
• Ice will build up over a period of time if the unit is operated at sub-zero
temperatures, allowing water to pool in the well at temperatures above
0.0°C. The user needs to drain the water build up after every use. Two
methods are available for draining the water: 1) Remove the insert from
the well and tip the unit upside down draining all water. 2) Take the unit
above 100°C for a period of one hour causing the water to evaporate.
• 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 calibrator is kept clean and clear of any for-
eign matter. DO NOT use fluids to clean out the well.
• The instrument should be handled with care. Avoid knocking or dropping
the instrument.
• If a hazardous material is spilt on or inside the instrument, 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 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 calibrator may be impaired or safety
hazards may arise.
