Maintenance

• With proper care the Product requires very little maintenance. Avoid operating the Product in an oily,

wet, dirty, or dusty environment.

• If the outside of the Product becomes soiled, wipe it 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 foreign matter. Do not use fluid

to clean out the well.

• Use a commercially available plastic or felt brush, of appropriate diameter for a tight fit without any

fluid, to clean the well. Complete the cleaning process by using cotton swabs and air to remove any
debris.

• Inserts should be cleaned periodically. For cold dry-wells operating below 0 °C, you should always

clean the inserts after operating the unit at or below 0 °C. Use emery cloth or other similar material
to clean the outside of the inserts. Ensure that the inserts are wiped clean of any debris loosened in
the buffing process. Periodic cleaning of the outside of the inserts ensures easy insertion and
removal of the inserts from the well.

• Handle the Product with care. Avoid knocking or dropping the Product.
• Do not drop the probe stems into the well, and avoid any other mechanical shock to the sensor.
• If a hazardous material is spilled on or inside the equipment, take the appropriate decontamination

steps as outlined by the national safety council with respect to the material.

• If the mains supply cable becomes damaged, replace it with a cord with the appropriate gauge wire

for the current of the Product. If there are any questions, call an Authorized Service Center (see

Contact Fluke Calibration

) for more information.

• Before using any cleaning or decontamination method except those recommended by Fluke

Calibration, users should check with an Authorized Service Center to be sure that the proposed
method will not damage the equipment.

• If the Product is used in a manner not in accordance with the Product design, the operation of the

dry-well may be impaired or safety hazards may arise.
