CALIBRATION RESISTOR INSPECTION [MZR-CD (RF Turbo)]

Note

• Perform the following test only when directed.

Resistance Inspection

1. Remove the calibration resistor.

2. Verify the calibration resistor rank number.

3. Refer to the table below and verify the resistance corresponding to the resistor rank number.

4. Measure the resistance between the calibration resistor terminals A and C using an ohmmeter.

• If not as specified, replace the calibration resistor.
