備註 (Remark)
* The above accuracy is specified base on the measurement frequency within 100 MHz to 2.5 GHz. If measurement is on other frequency range ( below 100 MHz and over 2.5 GHz ), the reading value just for reference only.
* The default selection is " Normal ", however if the measurement frequency is microwave or its frequency is near " 2.45 GHz ", it should select to " 2.45 GHz " will get the high precision.
