The meter is capable of providing an analog voltage signal proportional to the present flux density level. Calibration is set to 3.0 V full scale DC
or 3.0 VRMS AC, depending upon the mode of operation. This signal, available at the BNC connector, can be connected to a voltmeter,
oscilloscope, recorder, data logger, or external analog to digital converter.
Power consumption increases when using the analog output. If use of the analog output port is unnecessary, maximize battery life by disabling
the analog output feature.
ANALOG OUTPUT USAGE
See the SPECIFICATIONS section for frequency range and accuracy of the analog output.
The analog output signal is calibrated to 3 VDC or 3 VRMS depending on the selected mode. The analog output voltage is proportional to the
flux density being measured depending on the meter’s current range. For instance, when in the 30 mT DC range a reading of 12.3 mT relates
to an analog output voltage of 1.23 VDC. When in the 3 T range, a reading of 1.23 T produces the same output, 1.23 VDC.
The analog output can reach a maximum output of about 4.25 VDC in order to accommodate the peak value of a 3 VRMS AC signal. This
means that the analog output can be used to measure flux density levels that exceed the normal range of the displayed readings. For instance,
a level of 31.5 mT in the 30 mT range would normally result in a flashing 29.99 mT overrange condition. However, the output will still be +3.15
VDC.
The meter will apply an optimum amount of low pass filtering to the analog output signal based on the frequency of the detected magnetic field
and mode of operation (AC or DC mode).
