Instantaneous measurements:
Voltage
Frequency
Measurements and alarms:
NO:
:Circuit by number and phase
AMPS
: Instantaneous current in
Amperes (A)
CB
: Circuit breaker rating (A)
MIN
: Minimum current read (A) after
first registering a minimum current
MAX
: Maximum current read (A)
ZERO
: OK = Current has not read 0
after registering a current; ACTIVE =
Current has read 0 after registering a
current.
WARNING
: OK = No warnings
outstanding for this circuit; ACTIVE =
warning outstanding.
ALARM
: OK = No warnings
outstanding for this circuit; ACTIVE =
alarm outstanding
NO
: Subfeed circuit by number and
phase
Instantaneous measurements by
phase:
% LOAD
: %Load is a percent of the
Full Load amperage for this breaker;
“Full Load” is a user-specified percent
of breaker size, given in Modbus
register 494 (“Full Load Percentage”)
in the ESF Points List.
CREST FACTOR
: Peak current/RMS
current
%THD
: Total Harmonic Distortion as
percent
