7.1 FT3470-50 Magnetic Field Tester
7.1.3 Output Function
Supporting function
Magnetic flux density (T), Exposure level (%)
Output type
MON : 3-axis waveform output
REC : Resultant RMS level output (output via the X-axis.)
Exposure level output (output via the X-axis.)
Output rate
0.1 mV/display value count
An output rate based on the magnetic flux density unit T is used, even if the
magnetic flux density unit is G or A/m.
