Example Display and Measuring Ranges of Power Factor
Power factor
Symbol indicated when the value
is LAG power factor. Symbol indicated when the value
is LEAD power factor.
The following will appear when the measurement is out of range:
: Turns on while the maximum value is displayed.
: Turns on while the minimum value is displayed.
and the measured value blink alternately.
Measuring range: (LEAD) 0.500 to 1 to 0.500 (LAG)
* When the power factor is 1, the symbols indicating LEAD and LAG power factors are not displayed.
