Calibration
resistor*
* 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.
