Operating Instructions

The ED78S features different operating modes for measuring various types of electromagnetic fields.

To measure RF signals, such as from a router, ensure the meter is set to RF mode. This can typically be achieved by pressing the 'Mode' button until 'RF' is indicated on the display.

The LCD backlight can be manually controlled. To adjust the backlight and sound settings, first enter Hold mode by pressing the second button. Then, toggle the first button to cycle through the available options: sound-on/light-off, sound-on/light-on, sound-off/light-off, and sound-off/light-on. After selecting your desired setting, press the second button again to exit Hold mode. Note that the LCD backlight consumes significant battery power, so it defaults to auto-off after 10 seconds to conserve battery life.
