Operating Precautions

Before the Power Sensor is connected, the following precautions must be observed.

WARNING BEFORE CONNECTING THE POWER SENSOR TO ANOTHER

INSTRUMENT, ensure that the instrument and power meter are connected to

the protective (earth) ground.

Power Meter Calibrations

Power Meter to Power Sensor calibration procedures differ with the power meter.

Follow the calibration procedure located in your power meter’s user’s guide.

Temperature Sensitivity The sensitivity of the power sensor is influenced by

ambient temperature. The sensor should be recalibrated at each change in

temperature to obtain the most accurate results. Typical temperature sensitivity

variations are shown in Figure 1-7 for the 8481D power sensor.
