＜PID+BC adjustment＞
Input 4-20mA Calibration
Adjust zero point / span. Unlike Full Calibration, PID constant
automatic setting is not performed. PID set once remains valid. This
function is used when only zero-span adjustment is necessary.

"Span Calibration is now in Progress" is displayed.
After actuator operation stopped, confirm "Cal Error Status".

If display says "No Error", adjustment is completed.
5: This adjustment becomes available only after initial adjustment.
PID is automatically adjusted. Not like full calibration, zero span is
not adjusted. This becomes available when balance current
adjustment error(Balance current) is displayed.
