CALIBRATION METHOD
MODEL
DESCRIPTION
Zero
B, S,
T
A one point calibration - ideal for smooth surfaces, simply
place the probe on the uncoated substrate and the gauge will
automatically calibrate
Smooth
E, B,
S, T
A two point calibration - the user selects a suitable calibration
foil and a smooth, uncoated substrate (zero)
Rough/ 2 Point
E, B,
S, T
The ideal calibration method for rough or profiled substrates,
using two foils of known thickness - one above, another
below the target dry film thickness
Zero Offset
S, T
Calibration method for measurement when the substrate
profile/ roughness is unknown, or not accessible. A user
defined offset value is applied to the measurement reading
Auto
S, T
Ideal for repetitive inspections. The user stores known
calibration foil thicknesses into the gauge. When calibrating
the user is prompted to calibrate the gauge and the gauge
automatically adjusts the readings to the stored foil
thicknesses - simplifying and considerably speeding up the
calibration process
