VECTOR
SUMMATION In addition to the three standard channels, the vector summation is
dedicated to vector measurements. The resultant magnitude of the three
channels’ vector sum and relative vector angles are calculated and
displayed. A corrected analog output is also provided, analog outputs
are described later in this section
. Vector summation also supports the
hold ( MIN and MAX only ) and relative features, which were described
previously.
Using 7000 Series 3-Axis Probes
A three axis probe is shown in
Figure 6-6a . The orientation of the probe
and location of the “X” hall effect element is specified with a painted
mark. The straight side of the painted mark is parallel with the Y axis.
Figure 6-6b is an inside view that shows the locations of the X, Y, and Z
hall effect elements. The planes of the three Hall elements are
orthogonal with one another.
The instrument will detect the presence of a 7000 series 3-axis probe and
will automatically recognize X,Y, and Z regardless of how their cables are
connected to channels 1, 2, and 3. On the display and when using the
front panel keys; X, Y, and Z are always associated with channels 1, 2,
and 3 respectively.
A positive magnetic field entering the hall elements along the X, Y, and Z
axes as shown in
Figures 6-6a and 6-6b will produce positive readings.
