Calibrating The Probe - Elcometer 456 Operating Instructions Manual

A probe must be calibrated once it has been
fitted - refer to your Elcometer 456 Operating
Instructions and section 3 of these
instructions.

3 CALIBRATING THE PROBE

Special thickness standards are supplied
with F1 2 High Temperature PINIP™ Probes.
To use these special thickness standards,
place the appropriate thickness standard
over the end of the PINIP™ probe during the
calibration procedure. Remove the thickness
standard from the end of the PINIP™ probe
after use.
A High Temperature PINIP™ probe should
always be calibrated on a hot substrate. The
temperature of the substrate used for
calibration is best equal to the temperature of
the surface being measured.
The magnetic properties of the substrate can
be affected by the temperature of the
substrate. It is therefore advisable to use a
substrate for calibration that is of a similar
material and temperature to the coated
substrate being measured.
