measurement system
The display may be used to read a num-
ber of input and output measurements
made at different points in the system.
See figure 18 .
■ normal AC source 1
❏ phase-to-phase voltages,
❏ currents of the three phases,
❏ frequency;
■ bypass AC source 2
❏ phase-to-neutral voltage,
❏ phase-to-phase voltages,
❏ frequency,
❏ currents of the three phases;
voltage measurements
These measurements may be accessed
by pressing the "V" key 13 . The following
data is displayed.
Note:
M1: normal AC source
M2: bypass AC source
current measurements
These measurements may be accessed
by pressing the "A" key 14 . The following
data is displayed.
Note:
CF: crest factor
