8. Integration measurement (current integration
Ih, power integration WP)
Measurement type
Digital calculation from the measured value of I , P
Accuracy
±
1dgt. with respect to the value computed from the measurement
value for each channel ( I , P )
Number of measurement
64 times/s
Measurement item
Integration of current and active power for all channels is possible
The following items depends on settings

Function
Separate integration for each polarity (positive, negative, and total)
Integration for various control times
Automatic output to FDD/printer
Display of integration elapsed time
Cumulative integration by repeated start/stop operations
Start/stop/reset by external control
(Simultaneous control of selected channels; independent control
not possible)
Back-up of the integration value and integration elapsed time
during power failure
Restart of integration after restoring power failure
9. Load factor measurement function (
LF)
Calculation
Digital calculation from the positive integration value of active
power (only when the interval time is set)
Accuracy
Same as integration measurement
Number of calculation
Same as integration measurement
Measurement range
