Power Measurement How to Measure Power

How to Choose the Range Mode
NOTE For a Dual Power Sensor, you cannot set the range mode of the slave
channel, channel 2, directly. By default, the range mode of the slave
channel, channel 2, is the same as that for the master channel,
channel 1. See Table 8 on page 101 for more details.
You can choose either of two ranging modes from the Range mode
menu:
•<Auto>, the auto-ranging mode, ensures that the result has a
displayed value between 9% and 100% of full scale. The default state
is for automatic ranging to be enabled.
•<Manual>, which allows you to set a user-defined range.
