Use a set of traceable standards to periodically verify thickness measurements.
Record the displayed thickness readings to verify that the Magna-Mike 8600 is
operating at its expected accuracy (see Table 8 on page 75). Verifications may be made
on a monthly or annual basis depending upon the user’s judgment.
Olympus offers sets of traceable standards (Olympus P/N: 80CAL-NIS [U8771011]).
These sets are measured by a traceable metrology laboratory, engraved and labeled
with their true thickness, and delivered with appropriate certificates. The set may be
periodically recertified by any qualified metrology laboratory providing they (1) use a
ball or rounded anvil-style caliper, and (2) measure within 1.59 mm (1/16 in.) of the
disk center.
As with all thickness standards, gentle use is essential to avoid dents, which may
cause inaccurate measurements. If damage occurs to the traceable disks by use,
Olympus suggests replacing them.
