Magnet Stick
!The instrument for
checking magnetic fields
!Easy to use
!No metallic contact
Some exemples of its use
!Testing operating solenoid valves in pneumatic and hydraulic control
equipment
!Testing relays with coils and electrically controlled solenoid valves in all types of
vehicles and machineries
!Testing solenoid valves when servicing oil burners
The test lamp lights immediately and without metallic contact where there is a
magnetic field, e.g. an activated coil in a solenoid valve.
The test lamp responds to all kind of magnetic fields -from alternating current to
direct current and to permanent magnets.
Instructions for use
!First check the batteries according to the “functions check” instructions
below
!Just touch the test object with the Magnet Stick probe. If the lamp lights, the
object is electrically actived
!It is not necessary to unscrew the test object from its mounting on the equipment
in order to carry out the test - a magnetic coil can even be tested through its
protection cover
!It is not necessary to stop the machinery or the equipment in order to carry out
the test
!Sometimes stray magnetic fields from other nearby equipment may cause the
test lamp to blink momentarily. Close to an activated magnetic coil, however, the
test lamp will give a fixed light.
Function check
Unscrew the test magnet (or the instrument cap) and move it to the probe,
which shall then light. If the test lamp does not light - change the batteries.
Changing the batteries
To change the batteries unscrew entirely the cap at the back of the instrument.
The batteries are installed with the positive pole facing the test lamp
(instrument's probe). See specification below.
