Basic and Multipoint Calibration
75
• When replacing wear tips or probes
• If the probe tip is worn from abrasive material
• If the probe is replaced, dropped, or contacts highly-magnetic material
If the Magna-Mike 8600 has just been turned on, or if a probe has just been connected,
allow the gage to warm up for at least five minutes with the probe connected before
performing a calibration.
4.7 Calibration
The user can choose to perform a either a basic calibration or a multipoint calibration.
The basic calibration uses four points; BALL OFF, BALL ON, THIN SHIM, and
THICK SHIM. The multipoint calibration adds up to eight additional points to these
basic calibration points. The accuracy of the measurements will depend on the type of
calibration performed and the target being used. In general, a multipoint calibration
(a basic calibration with additional points) will improve the accuracy. The accuracy
for each target and calibration type is listed in Table 8 on page 75 and Table 9 on
page 76.
