INTRODUCTION
Thank you for purchasing this CARMELEC residual magnetic field meter. We
hope the following information will help you to understand all the functions of your
MAGNETIS. If you need further information, our team is entirely at your service.
GENERAL DESCRIPTION
MAGNETIS is a residual and/or DC magnetic field strength digital meter.
It is not appropriate for the measurement of AC magnetic field.
MAGNETIS is designed to test residual magnetism after demagnetization of
components, for instance parts which were inspected by magnetic testing. It is
equipped with a data processing algorithm which allows a quick reaction to value
changing while displaying a stable measurement.
This device complies with EMC European standard which is required for this
type of unit in the heavy industry.
PHYSICAL DESCRIPTION
Mechanical description
MAGNETIS is designed to be easy to use and as
light as possible.
It is manufactured with a reinforced ABS plastic
case which confers a good robustness to him. The
battery is easily accessible by a cover. A clip makes it
possible to hang MAGNETIS on the belt or in a
pocket.
The probe is fixed in a flexible way on the case in
order to avoid the transmission of possible mechanical
shocks.
Power is delivered by a 9V battery (type 6F22;
PP63; 6LR61). The battery polarity is automatically
detected.

Probe details

Power On/off
Press the central key to turn on your MAGNETIS.
An opening screen is displayed with CARMELEC logo and the « Help » tab in
the bottom right corner (See « Help menu » p. 6). Then MAGNETIS passes to
reading screen mode and therefore is ready for use.
MAGNETIS has a pre-programmed automatic power off after 3 minutes (except
special request). However you can turn it off by yourself by pressing the central key
for at least one second.
Display
The LCD display is equipped with a backlight which can be switched on using
the « LIGHT » function of the bottom-right menu. Take care; this function
considerably reduces the battery’s life.
The unit of measurement is: Ampere per metre (A/m)

Battery status indicator
It is possible to check the battery level of MAGNETIS with the battery charge
indicator on the top-left corner of the display. When the indicator is flashing, the
battery must be replaced by a new one. If it is not replaced and becomes unable to
make measurement, MAGNETIS is automatically turned off and « Low battery » is
displayed.
Help menu
A help menu can be accessed at the power on, by pressing the right key when
the logo screen appears with the help tab in the bottom-right corner.
Scroll the text using the right and left hand keys. Press the central key to exit
from help menu.
Data processing
MAGNETIS has a smart data processing method implemented.
It combines a moving average with an algorithm of measurement monitoring.
This method allows checking continuously if the displayed measure really matches
the instantaneous measure as detected by the probe.
If a shift due to integration in time is detected, the table of moving average is
automatically erased. After a very short time of fluctuation (0.5 second), the average
is rebuilt ensuring a good measuring stability.
In order to indicate the quality of the displayed measure, a bar-graph of stability
appears on the left side of the display when the moving average is restored.

MEASUREMENT PROCEDURE
Zero
MAGNETIS has an automatic zero process. It can by access by briefly pressing
(<1s) the central key. This setting is to be done by placing horizontally the meter, far
away from any magnetic mass and if possible in the east-west direction to free itself
from the terrestrial magnetic field (which can reach +/- 40 A/m).
Gain
To facilitate its use, MAGNETIS has no gain adjustment feature which would
be accessible by the user. This setting is made at the manufacturer factory and does
not fluctuate.
Checking before measuring
We advise you to check the meter before any use with a reference calibrated
magnet.
Measuring
The zero of the meter should be adjusted before taking any measurement (See
paragraph « Zero »).
The measurement is then taken by placing the probe face on the surface of the
component and by direct reading of the residual value on the display.
MAGNETIS incorporates features which allow you to obtain reliable measures:
Stability indicator
It looks like a bar-graph which is filled as MAGNETIS integrates the values of
the magnetic field. The reading is stable as soon as it disappears.
Maximum indicator
It allows keeping on the display the maximum detected value. This value is
erased during zero process.

MAINTENANCE
Annual calibration
To ensure the accuracy of your meter, we advise you to carry out an annual
checking of this device in a testing laboratory.
Cleaning
You can clean the device with any classic cleaning product.
