Back Panel - Fluke 6050H User Manual

7 Parts and Controls

Back Panel

(1) The bath tank is constructed of stainless steel. It is very resistant to oxida-
tion 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 deli-
cate 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 pro-
peller to provide mixing of the bath fluid. Proper mixing of the fluid is impor-
tant 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, pre-
vents 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.
7.3 Back Panel
The back panel of the bath contains the following features (see Figure 5 on
page 26): (1) the bath power cord, (2) the stirring motor power socket, (3) the
internal fuses, (4) the probe socket, (5) the RS-232 interface connector (op-
tional), (6) the IEEE-488 interface connector (optional), and (7) the drain tube.
WARNING! The drain tube is for factory use only.
(1) The bath power cord extends from the back of the bath. It provides power
for the bath temperature controller, the heaters, and the stirring motor. The cord
is plugged into an AC mains socket of 230VAC (±10%), 10 A, 50/60 Hz.
(2) The stirring motor power cord plugs into the socket labelled "STIRRER".
Power to the stirring motor is switched on by the POWER switch on the control
panel.
(3) The system and heater fuses are internal. Never replace a fuse with one of a
rating greater than that specified. The heater fuses protect against shorted
heaters.
