ACCURACY
While the update algorithm will allow the sensor to adapt to
typical air gap variations, major changes in air gap can adversely
affect switching performance. When characterizing sensor
performance over a significant air gap range, be sure to re-power
the device at each test at different air gaps. This ensures that
self-calibration occurs for each installation condition. See the
Operating Characteristics
table and the charts in the
Character-
istic Data: Relative Timing Accuracy
section for performance
information.
REPEATABILITY
Repeatability measurement methodology has been formulated to
minimize the effect of test system jitter on device measurements.
By triggering the measurement instrument, such as an oscillo-
scope, close to the desired output edge, the speed variations that
occur within a single revolution of the target are effectively nul-
lified. Because the trigger event occurs a very short time before
the measured event, little opportunity is given for measurement
system jitter to impact the time-based measurements.
After the data is taken on the oscilloscope, statistical analysis
of the distribution is made to quantify variability and capabil-
ity. Although complete repeatability results can be found in the
Characteristic Data: Repeatability
section, figure 11 shows the
correlation between magnetic signal strength and repeatability.
Because an direct relationship exists between magnetic signal
strength and repeatability, optimum repeatability performance
can be attained through minimizing the operating air gap and
optimizing the target design.
