6-1 QUALITY MAINTENANCE

PT2026 Calibration

Recalibrating a PT2026 consists of adjusting its internal reference clock, a
procedure only to be performed at the Metrolab factory. However, any properly
equipped calibration laboratory can certify the calibration by measuring the
internal 10 MHz reference clock output on the back panel. In addition, if you use
an external 10 MHz reference clock, the PT2026 does not need to be calibrated at
all.
All customers are of course free to fix the intervals at which they check the
calibration of their instruments, within the context of their quality assurance policy.
Metrolab's recommendation is to check the PT2026 calibration once every year.

MFC9046 Normalization

Normalizing a MFC9046 Probe-Array consists of reducing measurement
discrepancies of each probe in a same field to a few tenths of ppm. These small
measurement discrepancies are due to paramagnetic materials surrounding each
probe.
The Normalization process must be done by certified technicians only. Contact
Metrolab for more details (See section 1-3).
All customers are of course free to fix the intervals at which they check the
normalization of their instruments, within the context of their quality assurance
policy. Metrolab's recommendation is to check the MFC9046 normalization once
every year.
