BASIC SETTING
31
Note
The P.V status icon lights in red when the voltage
measurement circuit detects that the measured value
exceeds setting range by 3 folds (CF is set to 3) or 6
folds (CF is set to 6/6A).
Auto Range
The range is automatically switched according to the voltage and
current of input signal.
Range is shift up
The range is shifted up when either of the
following conditions is met.

Vrms or Irms exceeds the measurement range
by 130% at CF 3/6.

Vrms or Irms exceeds the measurement range
by 260% at CF 6A.

The Vpk or Ipk value of the input signal exceeds
the current setting range by 300% at CF 3.

The Vpk or Ipk value of the input signal exceeds
the current setting range by 600% at CF 6/6A.
Range is shift
down
The range is shifted down when all of the
following conditions are met.

Vrms or Irms is equal to or less than the
measurement range by 30% at CF 3/6/6A.

Vrms or Irms is equal to or less than the next
lower measurement range by 125% at CF
3/6/6A.

The Vpk or Ipk value of the input signal is equal
to or less than the next lower measurement
range by 300% at CF 3.

The Vpk or Ipk value of the input signal is equal
to or less than the next lower measurement
range by 600% at CF 6/6A.
