Results Interpretations - Sigma Metalytics PMV SM1601 User Manual

When testing a sample, brackets will be displayed. The icon and its location
indicates the results of the test.
Sample is consistent with the selected alloy type
The box cursor will fall anywhere inside of the brackets if the sample's characteristic
resistivity is consistent with the selected alloy type. The box cursor may not be in
the exact center of the brackets. That is okay. A result anywhere in the brackets
means the sample is consistent with the selected alloy type. Even on a good
result, test the size and weight of the sample to confirm it is the right density.
Sample is slightly inconsistent with the selected alloy type
If a star cursor falls outside of the brackets, to either the right or to the left, that
indicates that the sample is slightly inconsistent with the selected alloy type. There
could be reasons for a genuine sample to read outside of the brackets, including
but not limited to the sample being:
• Embossed or has high relief or design
• Very cold or very warm relative to the temperature of the device
• Too far away from the sensor
• Too thin or too small for the current sensor (see sensor selection)
• Off center from the sensor
• Very slightly impure, like higher than usual iron content
Confirm that the test is being performed properly. If everything is correct, this is a
questionable sample.
Sample is inconsistent with the selected alloy type
An X icon outside of the brackets indicates the sample is highly inconsistent with
the selected alloy type and is highly questionable. Further testing, more research,
and analysis by other non-destructive methods is highly recommended.
An arrow indicates that a sample is off the scale in that direction. This indicates
the sample is highly inconsistent with the selected alloy type.
