Used to test and calibrate an induction loop system in conjunction with a Magnetic Field Strength Meter.  It can be connected to the line level input of the induction loop amplifier.  Has a fixed level output of around 300mV rms and a crest factor of 4:1.  Uses a 9V PP3 bettery** (not supplied).

Also available (see Shopping Basket below):
AMPN Combined Magnetic Field Strength Meter (FoSmeter)

**Customers please note that not all 9V batteries for sale are the same size.  This means that some makes are too deep to allow the battery compartment cover to close properly - for example, Duracell Plus and Duracell Ultra.  Please check and use a suitable battery make with either the PNGN Pink Noise Generator or the AMPN Combined Magnetic Field Strength Meter.
