Performing Calibration

1. Connect the sensor 1 to Channel 1 of the 4540.
2. Connect the sensor 2 to Channel 2 of the 4540 – if applicable.

Note:

To ensure accurate calibration of Peak power sensors it is strongly

recommended to allow a warm-up and stabilization period of at least 3 minutes,
after a sensor has been connected to a powered-on instrument. For best
possible calibration we recommend to extend this period to 15 minutes.

the sensor specification.
