*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.
