Field Temperature Block Performance Analysis
8 Maintenance
The Field Temperature Block has been designed with the utmost care. Ease of opera-
tion and simplicity of maintenance have been a central theme in the product devel-
opment. With proper care, the instrument should require very little maintenance.
Avoid operating the instrument in an oily, wet, dirty, or dusty environment. Operating
the instrument in a draft-free environment facilitates improved performance of the
instrument.
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 plastic.
It is important to keep the well of the block clean and clear of any foreign
matter. DO NOT use uid to clean out the well.
The instrument should be handled with care. Avoid knocking or dropping the
block.
The removable inserts can become covered with dust and carbon material. If the
buildup becomes too thick, it could cause the inserts to become jammed in the
wells. Avoid this build up by periodically bufng the inserts clean.
If an insert should be dropped, examine the insert for deformities before
inserting it in the well. If there is any chance of jamming the insert in the well,
le or grind off the protuberance.
DO NOT allow the probe stems to drop into the well or harshly impact the well
bottom. This type of action can cause a shock to the sensor.
If a hazardous material is spilled on or inside the instrument, the user is
responsible 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, contact an Authorized Service Center for more information.
Before using any cleaning or decontamination method, other than those
recommended by Beamex, users should check with an Authorized Service
Center to insure the proposed method will not damage the equipment.
If the instrument is used in a manner not in accordance with the equipment
design, the operation of the instrument may be impaired or safety hazards may
arise.
The over-temperature cutout should be checked every 6 months to see that
it is working properly. In order to check the user selected cutout, follow the
controller directions for setting the cutout. Set the instrument temperature
higher than the cutout. Check to see if the display shows cutout and the
temperature is decreasing.
