INTRODUCTION
You have chosen the
MP -2000
magnetic field meter and you have done so for a good reason, because you have
bought a device that is not only designed and manufactured according to the state of
the art, but is above all light and convenient to operate.
The devices are manufactured exclusively in Germany.
We have made every effort to make this operating manual as short and as clear as
possible.
Nevertheless, if you should have any questions about operation, please contact our
competent service technicians, who are always ready to help. They will be pleased to
assist you.
Which magnetic fields can the MP-2000 measure?
The MP-2000 field meter measures all practically occurring magnetic fields, both DC
and AC, in a range from 0.1 to 40,000 A/cm (Oersted).
The device has two measurement ranges:
0 - 199.9 A/cm (Oersted)
200 - 40,000 A/cm (Oersted) DC / 200 - 20,000 A/cm(Oersted) AC
( 1 A/cm = 0.1 kA/m = 1.256 Oe(Gauss) = 0.1256 mT)
Measurement range switching takes place automatically.
The measuring unit can be switched between A/cm – kA/m - Gauss – mT.
DC fields, AC fields (effective value RMS) or peak value are displayed with storage.
Either a P-T2 / PT-4 tangential field probe, a P-A2 / P-A4 axial field probe or the spe-
cial P-Z2 / P-Z4 reed probe (0.7 mm thick) can be connected to the device.
A calibration standard is available on request for checking the calibration of the de-
vice.

And what is really unique:
For the first time, the MP-2000 uses measuring probes in which an integrated micro-
controller digitises and linearizes the special analogue signals directly in the probe.
This new technique is highly immune to interference and permits extremely precise
measurements even with high magnetic field strengths, where Hall probes no longer
operate linearly.
The built-in rapid peak value memory can measure pulse fields down to 0.1 msec.
In this device, the probe cable is pluggable at both ends (display device and probe)
and is therefore particularly service-friendly, because the customer can simply replace
the cable in the event of a cable breakage.
The convenient menu operation in several languages allows simple operation of the
device for the most part without an operating manual.
The MP-2000 offers the possibility to create up to 100 measurement storages (total
memory capacity: 10,000 measured values). Statistical evaluation takes place either
on the display or by connecting a printer or PC.
In addition to that, the MP-2000 has an analogue display with automatic measuring
range selection in order to quickly visualise changes or tendencies in magnetic fields.
For evaluation via a PC, a USB wireless interface is built into the device which, in
conjunction with the USB radio receiver supplied with the device, allows wireless
communication with a PC.
Various evaluation programs are available on request.

FAST START
•Connect the probe cable to the measuring probe and device.
•Switch on the MP - 2000 with the ON-OFF key. Automatic zero balancing
takes place when the device is switched on, therefore the probe should not be
in a magnetic field when doing so. The last measured value appears briefly on
the display, followed by the current measured value.
•To change the language (English is preset) press the MENU key:
Scroll through the menu using the arrow keys; confirm your selection using the
OK key.

IMPORTANT NOTES
1. Retention of the Stored Measured Values when changing the Battery
The stored measured values are retained even after switching off the device or
storing it without a battery.
2. Power Supply
The device is supplied as standard with three 1.5 V (Mignon) batteries. However, it
can optionally be powered by three 1.2 V NiCd rechargeable batteries. A suitable
charger is available from the factory and is connected to the serial interface.
Charging time: 8 – 10 hours.
The charger can also remain permanently connected!
3. Checking the Batteries or Rechargeable Batteries
The batteries must be replaced or the rechargeable batteries charged up as soon
as only 1 bar appears on the battery display when the device is switched on. If the
message ‘replace batteries’ additionally appears on the display, then the device
switches itself off automatically for protection if the battery voltage is too low. The
exact battery voltage can additionally be displayed for checking purposes:
The battery voltage should be greater than 3.0 V!
Used batteries are special waste and must be disposed of accordingly!
7. Automatic Power-Off
The device switches itself off automatically 2 minutes after the last measurement if
the measured value does not change.
8. Changing the Probe
To change the measuring probe, switch off the device first, connect the desired
measuring probe to the probe cable and then switch on the device again. If no
measuring probe is connected to the device, or if the probe cable has no connec-
tion to the device, a message is displayed when the device is switched on and the
device switches itself off again automatically.

I. MENU OPERATION
-0- key – Zero Point Setting
Zero point adjustment takes place after pressing the -0- key. The probe must not be
in a magnetic field during this time! After the zero balancing is complete, the display
shows ± 0.2 (influence of the earth’s magnetic field when moving the measuring
probe).
MEM key – Save Measured Value
After pressing the MEM key, the current measured value is saved in the selected
batch memory.
MENU Key
The various functions of the device are controlled via a menu. After switching on the
device, press the MENU key in order to call up the menu.
The arrow keys are used to select the menu item; the current selection has a black
background. The selected menu item is called up via the OK key; either a sub-menu
or the selected device function appears.
The Ckey is used to quit the device menu; the main menu field is selected with the
central blue key.
1. DC / AC / PEAK Selection
DC Field
Switch to the DC steady field range in order to measure static fields. The DC symbol is
shown behind the current measured value on the display.
RMS-AC Field
Switch to the AC alternating field range in order to measure alternating fields The AC
symbol is shown behind the current measured value on the display.
In the case of sinusoidal AC fields, the respective effective value (true RMS) is displayed.

PEAK Measuring Range P1 / P2
Switch to the peak value memory range P1 in order to measure peak fields < 500
A/cm (G) or < 50.0 kA/m (mT). The PEAK symbol is shown behind the current
measured value on the display. If the measurement range is exceeded, the display
shows:
You can switch to the peak value memory range P2 with the OK key; after that, re-
peat the measurement!
Switch to the peak value memory range P2 in order to measure peak fields >= 500
A/cm (G) or >= 50.0 kA/m (mT). If no peak value is displayed in the peak value
memory P2, this means that the peak value is < 500 A/cm (< 50 kA/m); in this case
select the peak value range P1!
If there is already a measured value in the peak value memory and a higher meas-
ured value is recorded, then the old measured value will be overwritten by the new
one. A short acoustic signal is sounded when the measured value is exceeded.
The peak value memory is reset via the -0- key.
When measuring AC fields in peak value memory mode, the peak value and not the
effective value will be saved if the AC field is sinusoidal!
2. Display

III. CHECKING OF THE MP-2000 WITH THE PRECISION CALI-
BRATION STANDARD:
It is not necessary to calibrate the device. The measuring probes are pre-calibrated
and are interchangeable.
A precision calibration standard with 180 A/cm is optionally available in order to
check the device with a measuring probe.
Tangential field probe:
Insert the probe, with the lettering N = north pole pointing upwards, into the slot of the
calibration standard until the probe latches at the front. Compare the displayed value
with the value of the calibration standard.
Axial field probe:
Insert the probe vertically into the cut-out with the red recess of the calibration stan-
dard and rotate it until the maximum value is displayed. Compare the displayed value
with that of the calibration standard.
IV. OPERATION WITH THE PRINTER
The device’s interface parameters have been set in the factory so that the MEGA-
PRINT data printer available from us can be connected without having to change the
interface parameters.
Operating instructions
1. Connect the printer cable to the device socket (RS 232C) and the printer.
2. Switch on the MP-2000; the printer then switches on automatically.
3. See menu operation item 4 – Transfer & PC
V. INTERFACE SETTINGS
The device’s interface parameters are set as standard for the USB wireless interface.
The USB interface driver included in the software must be installed so that a virtual
COM port can be assigned to the USB interface. If necessary you can check under
System Settings – Device Manager which COM port number is being used by the
USB interface so that you can set the correct COM port in the software.
