Instruction Manual
System Description
The byko-test
®
4200 dry film thickness gauge measures all non-magnetic
coatings such as lacquer, chromium, copper, zinc etc. on steel or iron.
The byko-test
®
4500 dry film thickness gauge additionally measures all
insulating coatings such as lacquer, plastic, enamel, etc. on non-
magnetic, metallic substrates, e.g. on aluminium, copper or brass.
Both gauges conform to national (DIN) and international (ISO, BS,
ASTM) standards:
DIN 50981, 50984 BS 5411 (3, 11), 3900 (C, 5)
ISO 2178, 2360, 2808 ASTM B499, D7091
General
This dry film thickness gauge was designed for various applications.
Despite its rugged design it should be handled correctly to insure proper
measurements at all time.
Do not let it drop and protect it from dirt, dust, humidity, chemicals and
aggressive vapours. After use please store the gauge in the protective
case.
As with all precision instruments large temperature variations can
influence the measuring result. Please avoid direct solar irradiation and
temperature shocks.
Due to the physical measuring principles the measurements can be
influenced by strong electromagnetic fields. Please stay away from e.g.
transformers, high voltage lines or discharge sources. Do not take
measurements on magnetized parts. Magnetic fields can affect the Fe-
measurements. Strong electromagnetic radiation can affect the NFe-
measurements.
The housing is resistant against most solvents. Use a soft damp cloth to
clean the housing.
Proper results can only be achieved with clean probes. Please regularly
check the probe tips and remove any dirt and paint from the rubies
If the gauge is not used for a long period, please remove the batteries
from the gauge in order to prevent leakage that can damage the unit.
In case of a malfunction of the instrument please do not try to repair it on
your own. Our customer service will be happy to assist you.

Change of Batteries
The battery compartment is on the rear side of the gauge. The battery
should be exchanged when the "BAT"-sign appears on the right side of the
display. Additional readings can still be taken even with the “BAT”-indication
before the gauge shuts off.
Note! Empty batteries should be disposed of properly. If possible, please
use the appropriate method.
Change of Unit µm/mil
Display of the readings is factory preset to the unit which is common for the
user (generally in µm). To change the unit from µm to mil or vice versa,
place the gauge on any surface or simply take a measurement. While
holding it placed, press the button until the buzzer beeps (approx. 6
seconds). The display will switch from one unit to the other.
Zero-Adjustment
A new zero-adjustment is required when using the gauge for the first time,
working with different materials, and after inserting a new battery. Place the
gauge on one of the zero plates in the case. For the Fe-probe please take
the steel plate; for the NFe-probe take the aluminum plate, when you want
to measure on aluminum; or use a suitable uncoated Fe- or NFe-substrate.
Please make sure the probe is placed perpendicular and evenly on the
surface of the zero plate or on your uncoated substrate. If the value
indicated is not within the basic tolerance, the gauge should be adjusted as
follows:
Place the gauge on the zero plate (substrate). Then press the button once.
On the display a control number appears and a beep sounds. Then lift off
the gauge at least 10 cm (4 inches) from the zero plate (substrate). A beep
sounds and another control number appears. Now the zero-adjustment is
completed.
When repeating measurements on the same spot, the reading may not
always be 0 µm or 0.00 mil, as the surface roughness, dirt, scratches etc.
might cause variances.

Handling
Place the gauge evenly on the object to be tested. The reading is
immediately shown on the display accompanied by a beep.
Simultaneously you will also receive the information, which measuring
method, Fe or NFe, is presently used in the gauge (important for gauges
with Dual-Probe).
If the gauge was placed incorrectly or lifted off before termination of the
measurement, or when being zeroed on a non-metallic substrate, an
error message “Err“ is displayed. Readings that exceed the measuring
range are indicated by the message “I
IFI” (infinite).
The gauge switches on automatically when being placed on the surface
and turns off automatically after about 10 seconds when no other
measurement is taken. For measurements on rods or tubes etc. align the
“V”-groove along the axis of the object to be tested.
Measurements with the Dual-Probe
The byko-test
®
4500 gauge combines both measuring methods for Fe
and NFe in one probe. Switching from Fe to NFe or vice versa is done as
follows:
Switch on the gauge. The current measuring method is displayed on the
left side of the LCD (e.g. Fe). Press the button for at least 1 second. The
new measuring method is shown on the left side of the LCD (e.g. NFe).
Please note, that it is possible to take readings with the non-ferrous
measuring method on a ferrous material. Due to the magnetic properties
of the material the displayed values are wrong. When using the non-
ferrous method, ensure, that the material is not ferrous. You can do this
in example with a control measurement using the ferrous method.
When using the NFe method, it is possible, that a measurement on the
supplied steel plate shows either a value or InFI. This can not influenced
and has no influence on the quality of readings in proper usage.
Display Messages
Fe = measurement on ferrous materials (steel or iron)
