you can

toggle the current input from manual ranging to auto ranging (indicated by an inverse A),
and back to manual ranging. For all but a few measurements auto ranging will work fine.
Manual ranging must be used for the data logging and dynamic torque measurement
and for those measurements where occasional large current peaks cause an undesired
up- and down ranging.

NOTE:

NOTE:

NOTE:

NOTE: When you are using a three phase Power Analyzer all three channels

are in the same voltage – and current range. If the signal level of one
channel is much below the others you will still achieve good accuracy.
The Power Analyzer exhibits excellent linearity for signal levels from
5 to 130 % of full scale.
