After a fast change of the flux density it is advisable to wait filter x time
before using the measured value.
The setting of the filter length has no influence on the analog output of the
Teslameter FM 302. The analog output always delivers the unfiltered
absolute signal with full bandwidth.
See also section 6.3.3.10 Command “filter” for extended possibilities for
controlling the measuring time via the USB interface.
6.3.1.15 Acoustic Feedback
Every new setting is acknowledged acoustically by a two-tone. At an error
message the feedback is a disharmonic tone.
See also section 6.3.3.21 Command “sound” for switching acoustic
feedback on and off via the USB interface.
6.3.1.16 Analog Output
The calibrated analog output is a BNC female connector. The output
impedance is 50 Ohm.
With the key “gain” the sensitivity (see section 6.3.1.9 Key “gain” –
Measuring Range) of the analog output is set, too.
The coupling (DC or AC) is determined by the setting of the measuring
mode(see section 6.3.1.8 Key “DC AC” – Measuring Mode).
The settings done with key “time” (see section 6.3.1.13 Key “time” –
Measuring Time) and “filter” (see section 6.3.1.14 Key “filter” – Filter) have
no influence on the analog output. The analog output always delivers the
unfiltered absolute signal with full bandwidth.
Also the measuring modes relative measurement (see section 6.3.1.11 Key
“rel abs” – Relative Measurement) as well as minimal measurement and
maximal measurement (see section 6.3.1.12 Key “min max” – Minimal
Measurement, Maximal Measurement) do not influence the analog output.
