3. Set the gauge magnet by rotating the scale wheel forward
(counter-clockwise) slightly until the indicator drops in the hole as the
magnet attaches itself to the item being tested.
4. Rotate the scale wheel backward (clockwise) until the indicator pops
up in the hole indicating the magnet has pulled away from the item
being tested.
5. Read the film thickness on the scale.
NOTE: Rough surfaces such as shot- or sand-blasted steel and casting
have uneven surfaces. Coating materials have a tendency to build
varying film thicknesses on surfaces of this type.
When measuring film thickness on rough surfaces, use one of the
following methods.
1. Follow the general operating instructions, but take multiple readings.
Use the average of these readings as a general indication of
film thickness.
2. Attach small, smooth steel panels to the work and coat the work as
usual. Measure the film on the panels. Remove the panels and then
coat the voids on the work.
When measuring on rod or cylindrical materials, align the “V” grooves in
the probe housing and instrument base with the rod or cylinder.
1. Periodically check the probe tip for foreign matter. Remove any
foreign matter with a clean, dry brush or a soft cloth.
2. Always store the gauge in its case when it is not in use.
NOTE: Do not attempt to calibrate your film thickness gauge. Consult a
qualified Nordson representative for calibration assistance.
The Nordson Magnetic Dry Film Thickness Gauge requires no calibration
under normal circumstances. If you require calibration instructions,
please contact your Nordson Corporation Representative.
