Power
Power to the bath is provided by an AC mains supply and passes through a filter to
prevent switching spikes from being transmitted to other equipment. Re fer to Section
3.1, Specifications, for power details.
To turn on the bath, switch the control panel power switch to the ON position. The stir
motor will turn on, the LED display will begin to show the bath tem perature, and the
heater will turn on or off until the bath temperature reaches the programmed set-point.
When powered on the control panel display will briefly show a four digit num ber. This
number indicates the number of times power has been applied to the bath. Also briefly
displayed is data which indicates the controller hardware configuration. This data is
used in some circumstances for diagnostic purposes.
Heater
The power to the bath is precisely controlled by the temperature controller to maintain
a constant bath temperature. Power is controlled by periodically switching the heater
on for a certain amount of time using a solid-state relay.
Fluid Drain
The fluid may be drained from the 6102 by tightly screwing the transport/pour lid onto
the top of the bath and pouring the liquid into an appropriate container.
Temperature Controller
The bath temperature is controlled by Hart Scientific's unique hybrid digi tal/analog
temperature controller. The controller offers the tight control stability of an analog
temperature controller as well as the flexibility and programmabil ity of a digital
controller.
The bath temperature is monitored with a platinum resistance sensor in the con trol
probe. The signal is electronically compared with the programmable refer ence signal,
amplified, and then fed to a pulse-width modulator circuit which controls the amount
of power applied to the bath heater.
