Owner manual

General:
The byko-test1200 measures all non.magnetic coatings
such as lacquer, paint, plastics, enamel, chromium, cop-
per, zinc, etc. on steel and iron (Fe).
Adjustment:
A zero-adjustment is required when using the gauge for
the first time or working with different materials, after in-
serting a new battery, or from time to time.
Place the probe of the byko-test1200 on the zero plate
enclosed in the case or on a respective uncoated sub-
strate used by you. Please make sure that the ring
around the probe is evenly placed on the measuring sur-
face. If the reading is not within the basic tolerance, push
one of the slides at the sides of the gauge. You will hear
a "Beep" and a control number will appear on the dis-
play. Lift the gauge at least 25 mm (1 inch) from the zero
plate. The gauge will "beep" again and another number
will be displayed. The byko-test1200 is adjusted now.
When repeating measurements on the same spot, the
readings may not always be 0.00, as the surface rough-
ness, dirt, scratches etc. might cause differences.
The gauge is delivered with a red protection ring around
the probe for better positioning and protection. This ring
can easily be removed by slightly turning and pulling. In
case of bent surfaces remove the protection ring in order
to achieve accurate measurements.
Measurement:
Place the byko-test1200 with its ring around the probe
plane on the object to be measured. Please make sure
that the circular probe ring is evenly placed on the sur-
face. On even objects, the two rear supporting points will
help to position the gauge. The measured value is im-
mediately indicated on the display accompanied by a
"beep". The display shows "Err" if the byko-test1200 is
placed incorrectly, and "Infi" if the measurement is out of
range. The gauge turns on automatically and switches off
after approx. 10 seconds if it is not used.
When measuring on rods align the "V"-groove in the ring
of the probe with the axis of the rod.
Note:
Please do not take measurements on magnetized
parts !
Converting from mil to µm and µm to mil:
In order to convert the displayed values from the mils-
mode to the µm-mode or vice versa, lift off the gauge
and push both slides on the sides of the byko-test1200.
The display will then convert the values accordingly.
Battery:
The gauge is powered by a 9V alkaline battery. The bat-
tery is located at the rear end of the gauge. If the blinking
sign "BAT" appears on the display, it is advisable to
change the battery.
Possible messages :
Err: incorrect use
Infi: wrong substrate (e.g. Aluminium, wood )
or measurement out of range
BAT: battery is getting weak, please exchange
