Rms math system Select true rms value or rectified mean value calibrated to the rms value
Math sync mode Edge: Select a signal. Computed using zero-crossings.
Auto Timer: Specify the time. Computed at specified time intervals.
AC: Select a signal. Computed using zero-crossings. Signal stop determined by a
stop prediction function.
AC+DC: Select a signal. Computed using zero-crossings. Signal stop determined by a
stop prediction function.
Switches to Auto Timer after stopping.
Channel selection for edge Select a single channel from own phase voltage, own phase current, or other voltage/current.
Sync channel filter If sync mode is set to Edge, low-pass filter can be selected.
Cutoff frequency: Select from 128 kHz, 64 kHz, 32 kHz, 16 kHz, 8 kHz, 4 kHz, 2 kHz, 1 kHz,
500 Hz, 250 Hz, 125 Hz, and 62.5 Hz.

Supported wiring systems Single-phase, two-wire (1P2W); single-phase, three-wire (1P3W); or three-phase, three-wire
(3P3W),
Three-phase, three wire system that uses a three-voltage, three-current method (3P3W;
3V3A); three-phase, four-wire system (3P4W)
Delta math function Three -phase, three-wire (3P3W) → three-phase, three wire system that uses a three-voltage,
three-current method (3P3W; 3V3A)
Three-phase, three-wire (3V3A) → three-phase, four-wire system (3P4W) (delta → star)
