8 General Operation

policies regarding flash points, toxicity, and such issues must be considered. You are responsible for reading the (material safety data sheets) and acting accordingly.

8.2Stirring

Stirring of the bath fluid is very important for stable temperature control. The fluid must be mixed well for good temperature uniformity and fast controller response. The stirrer is precisely adjusted for optimum performance.

8.3Power

Power to the bath is provided by an AC mains supply. See Section 3.1, Specifi- cations, for power details. Refer to and read the CAUTION at the front of this manual concerning brownout and over voltage protection. Power to the bath passes through a filter to prevent switching spikes from being transmitted to other equipment.

To turn on the bath switch the control panel power switch to the ON position. The stirring motor will turn on, the LED display will begin to show the bath temperature, 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 number. 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 cir- cumstances for diagnostic purposes.

8.4Heater

The power to the bath heater is precisely controlled by the temperature control- ler 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.

The front panel LED heater mode shows the state of the heater. The indicator glows red when the heater is on and is off when the heater is off. The indicator will pulse constantly when the bath is maintaining a stable temperature.

8.5Refrigeration

This bath uses a two-stage refrigeration system which requires special refriger- ants to enable it to reach low temperatures. This section describes some aspects of the cooling system and provides important information regarding refrigerants.
