About this app

Find the origin of electro magnetic fields (EMF) & DC currents with high precision through haptic feedback! Use linescan option for more accurate localization. Share your measurement as picture or data for interpretation and/or to friends. Ideal for crafting, soldering, building and repairing equipment.

Features:
-----------------
- Precise measurement of the magnetic field strength
- Localizing of spots with electric current flowing
- Point measurements or line scan
- Measure x-, y- and z- direction of the magnetic field
- Haptic feedback for precise and "blind" localization
- Share your measurements as image or data

Short description
-----------------------------
With the magnetic field & DC current detector, you can easily and elegantly examine the origin and strength of a magnetic field. Use line scans to investigate areas more accurate. Share your measurements as pictures or data file for yourself or your friends for interpretation.
The origin of a magnetic field is connected to high DC currents. For example, you can quickly and easily determine the location of a power supply, a large consumer, or a defective part within a device. With the haptic feedback, you can even do this without having to look at the screen. For a later evaluation, share your measurement data.

The magnetic field strength is detected with a sampling rate of 5 ms and an average of 50 ms. The accuracy is ~ 0.15 μT. In order to obtain quantitatively correct values for the magnetic fields, please calibrate the magnetic field sensor before application. You calibrate the sensor by moving the mobile phone in a loop and rotating around itself. Important: In a space where only the earth's magnetic field is present.

Alternating currents cannot be detected. For this, we are developing another app.

SMF APPS GbR accepts no liability whatsoever. The results obtained are an orientation value.
