- Pb
Value of the Proportional Band expressed in percentage of the value of the end of the scale. Proportional
band means the length of time in the measure field within which there is the variation of the regulation
probe exit alarm and therefore the adjustment of the heating element power.
- td
Derivative Time expressed in seconds. When there is a step variation of temperatures, the derivative
action induces a greater initial adjustment, so that the oven will have a greater power than it usual has
due to the proportional and integral action only. Since the error keeps existing, the derivative action
reduces the impact giving the integrative action the task of reducing the error.
- ti
Integral Time value expressed in seconds. The integrating action cancel the error between the chosen set
point and the temperature reached only by the proportional action. Integral time means the length of time
necessary to the integrative action to double up the proportional action
default parameters will be kept recorded.
- dEG Units °C/°F
This parameter allows selecting the temperature-measuring unit. By selecting "°C" all temperatures will
be expressed in Celsius degrees; by selecting "°F" all temperatures will be expressed in Fahrenheit
degrees.
- dEF
Default Parameter; this function allows choosing to set the thermoregulator with the P.B., T.I., T.D.
parameters either as a default or as a customisable adjustment. By selecting the "OFF" parameter and
confirming by the "E" key it is possible to modify the adjustment parameters, which will keep operational
even if the calibrator is turned off. By selecting the "ON" key (followed by the confirmation by pressing the
"E" key) the adjustment values will be set on the default ones recorded by the manufacturer, and
therefore not allowing to be changed. By turning the calibrator off the parameter will set on OFF but the
default parameters will be kept recorded.
- CodE
This is the Code to step the third menu level. Press 5 or 6 key to set the number recorded in the "
Cod1" parameter, and press "F" + 5keys at the same time to step to the third menu level. The default
set value is 2. If you lost the access key remember that it is possible to have the number by
reading the register 13 (item 10.3)
