Operation-PID B
PID B Prompts
After you step past the Set Point 2A prompt [SP2A] and the Set Point 2B
prompt [SP2b] to the Operation menus, the Series 998 displays the menu
selection ( [`SYS], [PidA] or [PidB] ) in the upper display and [OPEr] in
the lower display.
The Up-arrow > or Down-arrow key < selects another menu. Press the
Mode key µ to display the first prompt in the lower display and its value
in the upper display. Use the Up-arrow and Down-arrow keys to change
the value in the upper display. The new value will not take effect until
after a five-second delay or until you press the Mode key.
Proportional Band, Output 1B or 2B
Select the proportional band for PID channel A outputs. If set to
[```0] it functions as an on/off control, and the switching differential is
determined by the [HY1b] or [Hy2b] value (Output Menu). The decimal
precision is determined by [dEC1] (Input Menu).
[Pb1b] This prompt always appears.
