: Signal level coefficient [%]
When the signal level is less than 100 mV, the measurement accuracy is not
guaranteed.
When the signal level is set as a current, refer to Kv of the value calculated by
measurement signal amplitude setting [Arms] × 50 as the signal level [Vrms].
When the measurement signal amplitude setting is 3.0 mArms, refer to K
