Measurement Category • Anticipated Transient Overvoltage
Under safety standards (EN61010 Series, JIS C 1010 Series), measurement is classified into Categories II to IV according to themeasurement point's rated voltage to ground, current capacity (size of current that flows in a short-circuit fault), etc., and the transient
overvoltage that occurs at the measurement point.

CAT II :Measurement at a point from the power plug to the equipment's power circuits, where equipment is directly connected to an outlet.

CAT III :Measurement at a point on the power distribution cabling or power supply circuits, or at a point from the distribution panel to a distribution
terminal behind an outlet, where equipment (for example a fixed installation) takes electricity directly from a distribution panel.

CAT IV :Measurement at a point on a service drop to a building, or on the line from the drop connection to the power meter or distribution panel.

Measurement
Category

Rated voltage
to groundPower lines in factories and similar facilities will at times include transient overvoltage(impulse voltage) that is around 10 times the power source voltage.
The transient overvoltage of the measurement points must be predicted in advance,
and the instrument will need a safety design that will enable it to withstand suchovervoltage.

CAT IV4000 V

6000 VAssuming 600 V for the measurement point's voltage to ground, a Category IV location could potentially include transient
overvoltage of 8000 V. Hence, CAT IV measurement instruments are designed to withstand transient overvoltage of 8000 V.
CAT III measurement instruments can only withstand up to 6000 V, so if 8000 V transient overvoltage enters, it will cause
insulation breakdown that could result in electric shock.

Never measure a measurement point with a higher category number than the category indicated on the measuring instrument. Doing so could lead to a serious accident such as electric shock.

Rectification Methods: True RMS and Mean
A measuring instrument uses one of two rectification methods, “True RMS" or “Mean”. Using mean rectification assumes that the signal is based on a sine
wave without distortions in order to calculate the value. Distorted waveforms cannot be measured accurately using this method. As the performance ofequipment increases, so do distorted waveforms. In order to accurately measure in these situations, using the True RMS method is necessary.
