Phasor Diagram Display (Fresnal Diagram) - AEMC PowerPad 3945 User Manual

NOTE: K factor is only available when current (4A, 3A or 2A depending
on hook up) is selected from the choices on the right side of the screen.
Flicker is only available when voltage (3V or 2V depending on hook up) is selected
from the choices on the right side of the screen.
Flicker and K factor are available when L1, L2 or L3 are selected from the choices
on the right side of the screen.
DC current will be displayed, however the values are only valid when a current
probe capable of measuring DC is used. The MR193 probe is available for this
purpose.

Œ
Absolute value of voltage or current, depending on display selection.

Φ 12 corresponds to phase angle between channel 1 and channel 2
Φ 23 corresponds to phase angle between channel 2 and channel 3
Φ 31 corresponds to phase angle between channel 3 and channel 1
NOTE: This is valid for current (4A and 3A) and for single voltage (3V).
When the user chooses to look at a specifi c phase (L1, L2 or L3) ΦVA is the
phase angle of V in relation to A.
Ž
Current or voltage unbalanced ratio.

Phasor diagram displays selection by voltage, current or phase.
