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.
Applications:
This meter is specially developed for measuring or monitoring electromagnetic field, for example:
cell-phone station, hospital equipment, radar, micro-wave oven, radiation work, TV antenna, Radio station, welding
equipment, baking - equipment, television, computer, factory, laboratory, and other environment etc.
