4. Basic and Multipoint Calibration
Olympus recommends regular calibration (with regular verification) of the Magna-
Mike 8600 to ensure consistency and accuracy of thickness readings. This chapter
outlines how to choose probes, target balls, target disks, wire targets, when to
calibrate, and how to calibrate.
4.1 Probe Types
The Magna-Mike 8600 can be used with three different probes:
• Standard straight probe (Olympus P/N: 86PR-1 [U8470020])
• Right angle probe (Olympus P/N: 86PR-2 [U8470028])
• Low-profile articulating probe (Olympus P/N: 86PR-3 [Q7800004])
The 86PR-1 and 86PR-2 probes have the same measurement and maximum thickness
capabilities, but the 86PR-2 is shorter, has a handle, and is easier to use when the
probe is being used outside of the probe stand. The 86PR-2 probe (see Figure 4-2 on
page 62) is useful for special application where the longer 86PR-1 probe (see
Figure 4-1 on page 62) may be too large to fit into the measurement location.
The third probe (86PR-3) is a special low-profile probe designed to be as small as
possible for applications with very limited access space at the measurement location
(see Figure 4-3 on page 63). However, this probe has a more limited thickness range.
The head of the probe can be adjusted and locked at different angles. The 86PR-3
probe’s maximum measurable thickness is up to 4.06 mm (0.160 in.), depending on
the target being used.
