● If the results of one or more wiring check are NG, check the following:
Results
Voltage input judgment is NG.
Current input judgment is NG.
Phase difference judgment
(voltage - current) is NG.
Voltage phase judgment is NG.
Current phase judgment is NG.
Frequency source check is NG.
NOTE
There may be cases where the result of the check may show what is actually
correct wiring as NG and vice versa. For this reason, also check for an error in
the vector diagram or measured values.

Measures
• Check if the voltage probes are connected properly to the
circuit under test.
• Check if the voltage probes are connected properly to the
voltage input terminals of the meter.
• Check if the voltage range is appropriate to the input level.
• Check if the clamp-on current probe(s) is clamped onto the
circuit under test properly.
• Check if clamp-on current probe(s) is connected to the
current input terminal of the meter properly.
• Check if the current range is appropriate to the input level.
• Check if the voltage phase sequence is correct.
• Check if the direction of the arrows and the phase of the
clamp-on current probe(s) are correct.
• Check if the voltage phase sequence is correct.
• Check if the circuit under test and the setting of the wiring
system agree with each other.
• Check if the direction of the arrows and the phase of the
clamp-on current probe(s) are correct.
• Check if the circuit under test and the setting of the wiring
system agree with each other.
• Check if the voltage input selected for the frequency source
is stable.
• Check if the voltage probes selected for the frequency
source are connected properly.
