Measurement
conditions
Measurement cable length 0 m (Connect the measuring object to the SW9002's
connector.)
Use the specified connection cable between the switch mainframe and the target
measuring instrument.
Based on the conditions separately defined for each target measuring instrument.
Based on the guaranteed accuracy conditions for use in conjunction with an instrument.
(2) Combined measurement accuracy
The combined measurement accuracy for an instrument and the switch (main frame and module)
can be calculated using the following formula:
Combined measurement accuracy = Instrument ac combination measurement influence
