MODEL DESCRIPTION
B, S, A one point calibration - ideal for smooth surfaces, simply
T place the probe on the uncoated substrate and the gauge will
automatically calibrate
E, B, A two point calibration - the user selects a suitable calibration
S, T foil and a smooth, uncoated substrate (zero)
E, B, The ideal calibration method for rough or profiled substrates,
S, T using two foils of known thickness - one above, another
below the target dry film thickness
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
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
calibration process
considerably speeding up the
