9.4Secondary Menu

Functions which are used less often are accessed within the secondary menu. The secondary menu is accessed by pressing “SET” and “EXIT” simulta- neously and then releasing. The first function in the secondary menu is the heater power display. (See Figure 4 on page 36.)

9.5Heater Power

The temperature controller controls the temperature of the bath by pulsing the heater on and off. The total power being applied to the heater is determined by the duty cycle or the ratio of heater on time to the pulse cycle time. By knowing the amount of heating the user can tell if the calibrator is heating up to the set-point, cooling down, or controlling at a constant temperature. Monitoring the percent heater power will let the user know how stable the bath temperature is.

The heater power display is accessed in the secondary menu. Press “SET” and “EXIT” simultaneously and release. The heater power will be displayed as a percentage of full power.

To exit out of the secondary menu hold “EXIT”. To continue on to the propor- tional band setting function press “EXIT” momentarily or “SET”.

9.6Proportional Band

In a proportional controller such as this the heater output power is proportional to the well temperature over a limited range of temperatures around the set-point. This range of temperature is called the proportional band. At the bot- tom of the proportional band the heater output is 100%. At the top of the pro- portional band the heater output is 0. Thus as the temperature rises the heater power is reduced, which consequently tends to lower the temperature back
