Fitting/Changing The Battery; How To Make A Measurement - Conrad 2050 Bedienungsanleitung

Fitting/changing the battery

To keep your device functioning perfectly, you must fit a 9V battery
unit. You are alerted that a battery change is needed when the
lower green LED flashes or goes out during measurement. This
„undervoltage" is displayed when the battery voltage (under load)
is lower than approx. 6.5 V. This is how you change the battery:
Press lightly on the arrow marked on the battery compartment co-
ver, and then remove by sliding in the direction the arrow shows.
The used battery is now exposed. Remove the battery from the
battery compartment, releasing it carefully from the terminal clip.
Replace the consumed battery by a new one of the same type.
Only use alkaline batteries. After changing the battery, carefully
reclose the battery compartment, making sure that the cable of the
terminal clip is not jammed.
Under no circumstances operate the measuring
device while it is open. Never leave consumed bat-
teries in the device, since even batteries protected
against leakage can corrode and release chemicals
which are a health hazard and will fatally damage
the battery compartment. Used batteries must be
handled as hazardous waste and must be disposed
of in an environmentally acceptable manner. Collec-
tion bins are available at specialist distributors or
recycling centers.

Operation
Switch on the EMC Detector using the slide switch, setting to ran-
ge I or II. If you are not in the immediate vicinity of an electroma-
gnetic source, only the green LED (indicating operating mode)
should light up.

How to make a measurement

The following includes a general description, followed by the exam-
ple of measuring a monitor. After visual display of 10 mgauss (red
LED), there is an acoustic warning signal (intermittent).
a) Measuring in general
This is what you do:
a1 Switch on the EMC Detector via the slide switch (setting to I
or II). After a short stabilization phase, the measuring device
is ready for operation.
a2 Start by holding the measuring device horizontally in the di-
rection of the electrical device you are testing.
a3 Observe how the display changes as a function of your di-
stance from the electrical consumer device.
a4 Next, attempt to obtain the max. display by turning the mea-
suring device (still held in the direction of the test object) to
the left and right.
Important!
If the test object (electrical consumer device) is off, or is swit-
ched off, all LEDs on the measuring device (except the LED in-
dicating that the device is operational) should remain off. If not,
the display relates to the electromagnetic field of another con-
sumer device.
