Three-phase energy meter field calibrator
TT
2.53 Method for checking the connection of
TTTT
single
TTTT
-phase
TTTT
energy meter:
TT
Optionally select one of A, B and C-phase voltage
TTTT
TTTT
terminal
TTTT
of the instrument and connect to
the
TTTT
"
TTTT
fire"
TTTT
line of the measured energy
TTTT
TTTT
meter
TTTT
, and
TTTT
connect U0
TTTT
to "
TTTT
0"
TTTT
line;
TTTT
TTTT
optionally select
one of A, B and C
TTTT
-
TTTT
phase
TTTT
TTTT
current clip-on ammeter
TTTT
and connect
TTTT
to the
TTTT
TTTT
current
TTTT
TTTT
line of the
energy
TTTT
TTTT
meter;
TTTT
connect the
TTTT
pulse input
TTTT
TTTT
device to the energy
TTTT
meter’s optoelectronic
TTTT
socket
TTTT
.

Note:
TT
1.
TTTT
When the instrument's
TTTT
voltage
TTTT
is
TTTT
from the inlet
TTTT
port
TTTT
of fire
TTTT
TTTT
line, the
TTTT
TTTT
clip-on ammeter
TTTT
should connect to
TTTT
the
TTTT
TTTT
outlet
TTTT
TTTT
line of fire
TTTT
TTTT
line
TTTT
;
TTTT
otherwise it will affect
TTTT
TTTT
the accuracy of
TTTT
TTTT
calibration
TTTT
TTTT
errors

2.
TTTT
TTTT
When the
TTTT
instrument's
TTTT
voltage is
TTTT
TTTT
from the
TTTT
TTTT
outlet port of fire line, the
TTTT
TTTT
clamp
TTTT
TTTT
should
TTTT
connect
TTTT
to the
TTTT
inlet
TTTT
line of fire line
TTTT
;
TTTT
otherwise it will affect
