Frequently asked questions
Can it measure AC magnetic fields?
Yes. It measures AC magnetic fields in the 40-500 Hz range, in addition to DC fields.
How do I read the polarity of a DC field?
For DC fields the meter displays the magnetic polarity as N or S, so you can tell which pole faces the probe.
