: Signal level coefficient
When the measurement signal amplitude setting is less than 100 mVrms, 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] × 71 as the signal level [Vrms].
When the measurement signal amplitude setting is 2.1 mArms, refer to K
