Note
Accurate measurement may not be possible if
excessive noise is added to the input line.
• This product is designed to be used only with our
options.
Options from other companies are not compatible.
Measurement
• If there is harmonic or waveform distortion,
measurements may not be accurate. Please check
the current system before adopting it.
• It might not measure an instantaneous current
such as an inrush current or an welding machine.
• When measuring the loads below, it might not
satisfy the accuracy guarantee.
◊ Out of rating current, load with low power factor
◊ Load with winding current, load with ferromag-
netic field
• Power factor operation is a method that requires a
balanced load. The error might be considerable
when it measures unbalanced load.
