Fluke 6050H User Manual page 29

1. The bath tank is constructed of stainless steel. It is very resistant to
oxidation in the presence of most chemicals and over a wide range of
temperatures.
2. The control probe provides the temperature feedback signal to the
controller allowing the controller to maintain a constant temperature. The
control probe is a precision platinum resistance thermometer (PRT). The
control probe is delicate and must be handled carefully. The probe is
placed in the small hole in the top of the bath so that the probe tip is fully
immersed in the bath fluid. The probe cable connects to the bath at the
probe connector on the back panel.
3. The stirring motor is mounted on the bath tank lid. It drives the stirring
propeller to provide mixing of the bath fluid. Proper mixing of the fluid is
important for good constant temperature stability. The stirring motor
power cord plugs into the back of the bath at the power socket labelled
"STIRRER".
4. On the bath lid is a large rectangular access hole and a small circular
access hole. These holes are used for placement of thermometers and
devices into the bath. When possible the access holes should be
covered.
5. An access hole cover is recommended to cover the large square access
opening in the top of the bath. This improves bath temperature stability,
prevents excess fluid evaporation or fumes and increases safety with hot
fluid. The user may drill or cut holes in the cover to accommodate the
instruments to be calibrated or immersed in the bath. Spare covers are
available from Hart Scientific.
6. The drain tube, located at the lower left corner of the bath, is for factory
use only.
