Magnotest II Operating Manual page 1
The Instrument MAGNOTEST II measures the magnetism of an object and displays
the amount by means of red lights. The displayed amount is a relative value,
(strong, weak or not at all magnetic. )
Important : Due to the fact that magnetic fields are existing in many places, the
Magnotest II has to be adjusted in case not all red lights are off when
you first put it into operation the very first time.

MAGNOTEST II Operating Manual page 2
The MAGNOTEST II informs you if an object is magnetic (strong, weak or not at all.)
To remove the magnetism of an object, we recomend the use of the
Greiner-MAGNOMATIC.
1 Working conditions:
1.1 Power supply 4 batteries UM3 or power - transformer 6 volt DC.
1.2 Workplace Do not use the Magnotest II near magnetic fields like :
transformers, speakers, motors etc.
1.3 Temperature. Use the Magnotest II in room-temperature.
2 Putting into operation:
2.1 Switch on : Press switch on left side (yellow LED (ON) lights up)
Warming-up time: ca. 3 minutes
2.2 First operation
and change of Turn regulating device (Adjust) to ca. middle position
workplace: (white line shows ) and turn in front the calibration
potentiometer until all red lamps are off. Turn this small
screw with plastic screwdriver only.
3. Measuring:
Important: If not all red lights have gone off before testing an
object, following adjustment has to be made.
3.1 Adjustment Magnotest without object - turn regulating device in such
a manner until all red lights have gone off.
3.2 How to measure Put the object to be measured direct onto the center point.
Longish objects like screws etc. usually signal a stronger
magnetism at their head or face.
For small objects you must use a pair of tweezers made
of brass.
3.3 Interpretation of the
deflection : Relative values are being shown.
This shows if an object is strong, weak or not at all
magnetic.
2 or 3 red lamps
light up : The object is relatively weak magnetic and can be demag-
netized with the Greiner Magnomatic until all lamps are off.
4 red lamps light
up : The object is relatively strong magnetic. Press weakener
(1/4); this will show a quarter of the effective magnetism.
Demagnetize the object with the Greiner Magnomatic until
it shows a noticeable weaker magnetism without using the
weakener (1/4).
