A circuit arrangement for the controlled return of a pointer driven by a
stepping motor in the event of failure of the supply voltage includes a
control circuit for actuating the stepping motor. The supply voltage at
least for the control circuit for the stepping motor is buffered with at
least one buffer capacitor, the capacitance of the at least one buffer
capacitor being such that the buffer capacitor supplies the control
circuit for the stepping motor with electrical power at least until the
control circuit has moved the pointer driven by the stepping motor to a
default position. The default position is a zero position in relation to
the scale on the display apparatus or to another indicated value which is
noncritical in relation to the scaling on the display apparatus.
