When using the testers, voltmeters, or multimeters which show only the mean value, not
Rms values, carry out the following procedure.
1. Measure the line voltage.
2. Referring to the Mean Value Chart corresponding to each voltage area, see the figure
under the voltage obtained in step 1.
If the line voltage is 125 V and Rms value is 81 V, for example, the mean value is 54.5 V.
Therefore, it is recommended that the voltage be adjusted so that the mean value is set as
close to 54.5 V as possible.
