4.2 Connection Methods
The wiring check result is NG.
The voltage input
is NG.
• Do the voltage clips grip the wires properly?
• Is the voltage cable properly inserted into
the voltage input terminal of the 3169-20/
21?
The current input
is NG.
• Is the clamp-on sensor securely inserted
into the current input terminals?
• Is the set current range too large for the
input level?
The voltage phase
is NG.
• Are the voltage cables connected to the cor-
rect terminals?
The current phase
is NG.
• Does the arrow of the clamp-on sensor point
to the load side?
• Is the clamp-on sensor connected to the cor-
rect terminals?
The phase differ-
ence (I-U) is NG.
• Are the voltage cables and clamp-on sensor
properly connected?
• Does the arrow of the clamp-on sensor point
to the load side?
• Is the power factor of the line to be mea-
sured too low, such as 0.5 or less?
The voltage bal-
ance is NG.
• Does the connection method of the line to be
measured differ from that set?
• Do the voltage clips grip the wires properly?
• Is the voltage cable properly inserted into
the voltage input terminal?
