Power Meter Operation

Calibrating the Power Meter

Calibration Procedure Using HP E-Series Power Sensors

The following procedure describes how you calibrate the power meter with an HP E-series power sensor. Since the power meter automatically downloads the HP E-series power sensor’s calibration table there is no requirement to enter the reference calibration factor. The power meter identifies that an HP E-series power sensor is connected and will not allow you to select certain softkeys. The text on these softkeys appears grayed out.

Note

The following procedure details the calibration for channel A. To

 

calibrate channel B use the same procedure using the equivalent

 

channel B softkeys.

Calibration Procedure using HP 8480 Series Power Sensors

The following procedure describes how you calibrate the power meter with the HP 8480 series power sensors.

There are a variety of different methods to connect the power sensors to the power meter depending on the model of power sensor you are using. Refer to Table 2-1 on page 2-7 for details on connecting different power sensor models.
