When checking the over-temperature cutout, be sure that the temperature
limits of the bath fluid are not exceeded. Exceeding the temperature limits
of the bath fluid could cause harm to the operator, lab, and instrument.

baths should be kept in close proximity to the instrument.
If the mains supply cord becomes damaged, replace it with a cord of the appropriate
gauge wire for the current of the bath. If there are any questions, call an Authorized
Service Center (see Authorized Service Centers in Chapter 1) for more information.
Before using any cleaning or decontamination method except those recommended by
Fluke, users should check with an Authorized Service Center (see Authorized Service
Centers in Chapter 1) 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 equipment design,
the operation of the bath 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 in Reset Cutout in Chapter 9, for setting the cutout. Both the manual and
the auto reset option of the cutout should be checked. Set the bath temperature higher
than the cutout. Check to see if the display flashes cutout and if the temperature is
decreasing.
When using silicon oil, the bath will require periodic maintenance. The silicon oil
will condense on the bath during normal operation due to the outgasing of the oil.
How often and how long the bath is operated at higher temperatures determines how
often the maintenance will have to be performed. Simply wipe down the oily areas of
the bath with a mild degreaser such as 409®. Do not spray the degreaser directly on
the bath. Spray the degreaser on a cloth and wipe the bath down with the cloth.
Repeat the process as often as necessary to keep the oil from collecting on the bath. If
oil is allowed to collect on the bath, it may run into the bath and collect on the
interior of the bath causing internal damage that may affect the lifetime of the
instrument.
