Note (
27
) If this unit directly measures an inverter output of cycle control, SCR phase angle control or PWM control,
an error may increase due to its operation principle.
Note (
28
) Analog output, pulse output, alarm output and external operation input are options.

) At the case of one-way deflection setting of bar graph. Digital meter measures reverse power to -15%
full scale.
Note (
32
) It can usually check the maximum value and the minimum value by MAX/MIN switch operation from a display.
