non-ferrous metals
The Check•Line 3000EZ Series of coating thickness gauges provide
accurate, non-destructive measurement of:
• All non-magnetic coatings, such as varnish, paint, enamel,
chromium, copper, zinc, etc. on steel and iron. Measurements
in the F mode (Ferrous) are carried out according to the
Magnetic-Induction method.
• All electrically insulating coatings, such as varnish, paint, enamel
on non-ferrous metals (aluminum, brass, stainless steel, etc).
Measurments in the N mode (Non-ferrous) are carried out
according to the Eddy-Current method.
NOTE: 3000EZ Series gauges operate in accordance with the
following international standards related to coating thickness
measurment:
Magnetic Induction
DIN EN ISO 2178, ASTM B499, DIN 50 982
Eddy-Current:
DIN EN ISO 2360, ASTM D1400

3.1 On/Off Switch
To turn the gauge on, press the ON/OFF Switch briefly
(see photo on page 3). Press and hold the ON/OFF Switch
for 2 seconds to turn the power off.
Note: The gauge will power off automatically after
90 seconds of non-use.
3.2 Selection of Measuring Units

2. Press and hold the ZERO and STATS keys simultaneously
3. While continuing to hold down the ZERO and STATS
keys, turn the power ON.
3.3 Manually setting the measuring mode
DCFN-3000EZ Only
In some cases, especially with varnish applied to zinc on steel,
it is advisable to manually set the measuring mode—F mode
(Ferrous) for measurements on steel/iron, N mode
(Non-ferrous) for measurements on non-ferrous metals.
Setting the measurement mode
1. Turn the gauge on by pressing the ON/OFF switch.
2. Press the ZERO and STATS keys simultaneously to
change the measuring mode. Each time the keys are
pressed the mode will change.

3.5 Battery Replacement
3000EZ gauges use 2x AAA alkaline batteries. When battery
power becomes low, the BATTERY INDICATOR will begin
to flash. The gauge will continue to operate, but the batteries
should be replaced as soon as possible. When battery power is
depleted, the Battery Indicator will remain
on continuously,
indicating that less
than 60 seconds of
power remains before
the gauge will shut off.

6.0. ONLINE STATISTICS DISPLAY
Every time a measurement is
take, a pair of statistical values
appear in the lower part of the
display, as shown at right.
For example:
n = 12 x = 2.8 mils
(n = number of measurements ; x = average)
Each time the STATS key is pressed, the number of measurements
and a different statistical value will appear, allowing the user to
easily scroll through statistics menu in the following sequence:
Press n = number of measurements; x = average
Press n = number of measurements s = standard deviation
Press n = number of measurements max = maximum reading
Press n = number of measurements min = minimum reading
You can pre-select a required pair of values by means of the STATS
key, for example n = 12 s = 0.1 mils, and have it displayed during
the entire measurement data recording process.
Note: After the stistical values are deleted, or before new
measurments are made, the display will show:
n = 0 x = mils
Important: If a series of measurements is meant to be statistically
evaluated, the old statistical values must be deleted
before starting a new series of measurements.
4.0 MEASURING USING FACTORY CALIBRATION
1. Press the ON/OFF switch to turn
the gauge on.
2. If the ZERO icon does not appear
in the upper left corner of the
display, the preset factory
calibration is activated.
If the ZERO icon does appear, it
indicates that a Zero Procedure
has been performed. See Clearing
a Zero Setting, Section 5.2 before
continuing.
3. Place the gauge on the test object and read the measurement. Lift
the gauge off of the test object by at least 1 inch (2.5 cm) before
taking another reading.
Note: Using the factory calibration, you can immediately carry out
measurements on flat and slightly curved surfaces. On strongly
curved or rough parts it is recommended that a ZERO procedure
be performed (see section 5.0).
DCFN-3000EZ Only: The DCFN-3000EZ automatically recognizes
whether the base material is a ferromagnetic steel or a non-ferrous
metal and will display the correct reading.

5.0 PERFORMING A ZERO PROCEDURE
To obtain more accurate measurements on strongly curved or rough
parts, you should carry out the ZERO Procedure on a similar curved
reference piece without coating.
1. Press the ZERO key. ZERO flashes in the display.
2. Place the gauge on the bare surface several times. Lift the gauge
off of the surface by at least 1 inch (2.5 cm) between placements.
3. Press ZERO key again. The display shows ZERO
4. You can now carry out additional measurements.
Note: Zeroing is required if the convex radius of curvature
• is smaller than 1.2” (30mm) on steel parts,
• is smaller than 2.4” (60mm) on non-ferrous metal parts.
5.2 Clearing a zero setting and restoring factory
calibration
If the ZERO icon is shown on the display after switching
on (see top photo below), a custom calibration is activated.
To clear the custom setting:
1. Press the ZERO key twice. The ZERO icon disappears.
The factory calibration is active.You can now take
measurements using the factory calibration.
5.1 Checking accuracy
The foil standard included in the complete kit can be used
together with the suppled zero plates (Fe or Al) to check the
accuracy of the gauge. After zeroing, the measured thickness
of the foil will be displayed within the tolerance of the foil
plus the gauge accuracy.
