備註 (Remark)
* EP-04L probe's accuracy is specified within 400 KHz to 100 MHz only. If measurement frequency range is < 400 KHz, the reading value just for reference only.
* EP-03H probe's accuracy is specified within 100 MHz to 2.5 GHz only. If measurement frequency range is < 100 MHz or > 2.5 GHz , the reading value just for reference only.
* For precision measurement consideration, it should select the " Frequency Team point " near the frequency value of measuring object.
