NOTE
• Calibration can also be made for External operation. Set the frequency in the External operation mode, and make calibration
in the above procedure.
• Calibration can be performed during operation.
• For the operation from the parameter unit, refer to the Instruction Manual of the parameter unit.
 Terminal CA calibration (C0 (Pr.900), C8 (Pr.930) to C11 (Pr.931))
• Terminal CA is initially set to provide a 20 mADC output in the full-scale state of the corresponding monitor item. The
calibration parameter C0 (Pr.900) allows the output current ratio (gains) to be adjusted according to the meter scale. Note
that the maximum output current is 20 mA DC.
• Set a value at the minimum current output in the calibration parameters C8 (Pr.930) and C9 (Pr.930). The calibration
parameters C10 (Pr.931) and C11 (Pr.931) are used to set a value at the maximum current output.
• Set the output signal values (output monitor set with Pr.54) at zero or at the maximum current output via terminal CA using
the calibration parameters C8 (Pr.930) and C10 (Pr.931). The full scale for each monitor is 100% at this time.
