5. Battery Installation
The BSIDE K7 EMF Meter requires 3 AAA batteries for operation. Follow these steps to install the batteries:
- Locate the battery compartment cover on the back of the device.
- Slide or unclip the cover to open the compartment.
- Insert 3 AAA batteries, ensuring correct polarity (+ and - terminals match the markings inside the compartment).
- Close the battery compartment cover securely.
6. Basic Operation
6.1 Power On/Off
- To power on the device, press the ⏻ button. The LCD display will illuminate.
- To power off the device, press and hold the ⏻ button until the display turns off.
6.2 Measurement Modes
The device can measure electromagnetic fields (H-Field), electric fields (E-Field), and ambient temperature. Use the SEL * button to cycle through these modes.
6.2.1 Electromagnetic Field (H-Field) Measurement
In this mode, the device measures magnetic field radiation. The reading will be displayed in mG (milligauss) or µT (microtesla). Use the UNIT button to switch between mG and µT.
6.2.2 Electric Field (E-Field) Measurement
This mode measures the strength of the electric field, displayed in V/M (volts per meter).
6.2.3 Ambient Temperature Measurement
The device can also display the surrounding air temperature. Use the UNIT button to switch between Celsius (°C) and Fahrenheit (°F).

6.4 Data Hold and MAX Measurement
Press the HOLD MAX button to:
- Hold Data: Freeze the current reading on the display. Press again to release.
- MAX Measurement: Display the maximum value recorded since the device was powered on or the MAX function was reset.
6.5 Flashlight Function
The integrated flashlight can be activated for use in dark environments. Refer to the device's specific button layout for flashlight activation, typically a dedicated button or a long press of an existing button.
