Operation-PID A or B

PID A or PID B Prompts

After you step past the Set Point 2 prompt [`SP2] and the Idle Set Point
prompt [IdSP] to the Operation menus, the Series 988 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 µ.

Proportional Band, Output 1A or 1B

Select the proportional band for PID output 1. If set to [```0] it func-
tions as an on/off control, and the switching differential is determined by
the [HYS1] value (Output Menu). The decimal precision is determined by
[dEC1] (Input Menu).

[Pb1A] This prompt always appears.
