・
This meter is of average value response.
Frequency range: 50/60 Hz (Sinusoidal wave AC)
・
Accuracy is specified when an object is measured
at the center of the clamp sensor (CT),
・
A guide for a range of conductor positions
for accuracy guarantee
In other places of conductors to be
measured, the accuracy is as follows:
A area: 4% is added to the specified
accuracy.
B area: 1% is added to the specified
accuracy.
・
For accuracy when the indicated value is 15% of
the range or less, 8 dgt is added to the accuracy.
・
An induction error below 0.06 A/A may occur due to
influence of current flowing in adjacent conductors.
・
It may malfunction when measuring voltage/current in
the inverter circuit.
