* Not needed when the operation panel (FR-DU04) or
parameter unit (FR-PU04) is used for calibration. Used when
calibration must be made near the frequency meter for such a
reason as a remote frequency meter. However, the frequency
meter needle may not deflect to full-scale if the calibration
resistor is connected. In this case, use this resistor and the
operation panel or parameter unit together to make calibration.
