External noise up to the level shown below is treated as noise voltage, but levels higher than this
could lead to malfunctioning or damage to the internal circuit. Although the case is made from
fireproof resin, do not mount it next to flammable materials.
Between operating power supply terminals
Noise voltage
1,500V
Noise wave form (noise simulator)
Rise time: Pulse width: 1 μs, 50 ns
Polarity: Cycle: 10 ms
Note) Accurate measurement may not be possible if excessive noise gets added to the input line.

This product is designed to be used only with our options.
Options from other companies are not compatible.
■
As to measurement
・
If there is some distortion by harmonic or waveform, it may not measure correctly.
Please check with the actual system before adopts it.
・
It might not measure an instantaneous current such as an inrush current or an welding machine.
・
When measuring the below loads, it might not satisfy with the accuracy guarantee.
Out of rating current, Load with low power factor,
Load with winding current, Load with ferromagnetic field
・
Power factor operation is a method assuming balanced load. The error might be big when it
measures unbalanced load.
■
Static electricity
・
Discharge static electricity touching the grounded metal etc. when you touch the unit.
・
Excessive static electricity might be generated especially in a dry place.
■
Cleaning
・
Wipe dirt of the main unit with soft cloth etc. When thinner is used, the unit might deform or be
discolored.
■
Power supply
・
Connect a breaker to the voltage input part for safety reasons and to protect the device.
The breaker that connects to the voltage input part must arrange at the position easily reached,
and display shows it is the breaker of the equipment.
・
Do not turn on the power supply or input until all wiring is completed.
■
Before power on
Please note the following points when turning on power at the first time.
・
Confirm there are neither wiring rubbish nor especially an electrical conduction when installed.
・
Confirm neither the power supply wiring, the I/O wiring nor the power-supply voltage are wrong.
・
Tighten the installation screw and the terminal screw surely.
・
Use an electric wire applicable to the rated current.
