Mitsubishi Electric FR-E500 Instruction Manual page 203

Note: 1. Use FFT to measure the output voltage accurately. It can not be measured
accurately with a meter or general instrumentation.
2. When the carrier frequency exceeds 5kHz, do not use the instrument because
overcurrent losses occurring in the metallic parts inside the instrument will
increase and may lead to burnout.
In this case, use an approximate effective value type instrument.
* The value within the parentheses is for the 400V class.
