1. FIRST STEPS BEFORE START
Remove plastic protection from the screen.
Attach three-axis Hall probe to the instrument.
Turn on teslameter. Use push-button located at the back of teslameter.
Instrument may be supplied with internal
battery or external AC adapter with
stabilized 9 V output - see POWER
socket. Adapter plug-in automatically
disconnects the battery. Do not use
rechargeable batteries.
Note: connecting of external power supply
with voltage higher than 9,5 V
automatically switch off teslameter.
When teslameter is initially turned on -
logo „RX-25” will be illuminated for few
seconds. Immediately after this the
instrument automatically starts to do
zeroing relative to the magnetic field
existing around of probe.
For more precise and absolute
measurements, after at least one minute of
instrument being on, it is recommended to
repeat probe zeroing by placing probe into
attached Zero Field Chamber and then
choosing zeroing function from Menu.
2. FRONT PANEL OPERATION
Access to Menu ( see page 5) and a choice of desired modes and functions is
showed on the Menu diagram. All operations of the instrument are controlled by
four buttons only: Esc (menu/measure change), (up cursor), (down cursor),
-ENTER (circular horizontal cursor ). From any position at Menu it is
instantaneously possible to enter to measure mode and inversely simply by
using the Esc button!.
Black label position on the display means active function at the time.
Note that menu on the display of horizontal functional branches is subdivided
vertically on the screen. Therefore, horizontal cursor initially moves vertically
and then horizontally. This corresponds exactly to horizontal positions of Menu.

Three „position buttons”enable very fast access to the main functions without
searching the Menu.Therefore, successive pressing of down button
( )enables change of teslameter resolution from 0,001 mT to 0,1 mT.
Up button ( )changes active axis: X/Y/Z/Vect. Besides horizontal button
( -ENTER)has two additional functions.
First, it activates direct access to Relative mode when pressed for more than
two seconds in the measure mode. Second - in the vector mode only –it
generates full screen projection of measured parameters, i.e. X, Y, Z axes and
Vector results.
In order to go out from Relative mode the Menu must be entered.
When pressing the horizontal button for two seconds, while at the Peak Hold
mode –previous measurements are deleted and new actual measured magnetic
field is established as zero.
The rest of functions and modes of measurement are accesible from Menu only.
3. DISPLAY VIEW
Besides of measured results placed at central part of screen, additional
informations are visible on the display:
F - filter is ON,
R - Relative mode is ON,
↑-Peak Hold mode is ON,
- change battery.
Result of temperature measure is placed at the bottom of left screen
corner (this function is activated from Menu only!).
Units of measurements (Gs, mT, kA/m) are presented at the right hand site
of the bottom of the screen.
Standard mode of measure on the
screen, where:
0,29 - value of vector of magnetic
field measured,
Gs - chosen units of measure,
F - digital filter of result is ON,
13,1 °C – temperature of Hall sensor,
Full mode of measure where:
V - vector value of magnetic field,
X, Y, Z - values of magnetic field along
of X, Y, Z axes respectively.

5. GENERAL REMARKS
Teslameter has two additional output sockets: serial port (RS 232) for data
transmission and remote control by PC and analog port for direct view on
oscilloscope of AC magnetic field shape at AC mode of measurement.
If there is no COM port in PC, please use standard COM /USB port converter.
Instrument saves all utilized settings before being turned off.
The attached MagPro RX-25.3.9 software allows for collecting
results of measurements, write them to a file, show magnetic field variations at
real time on the display, and remote control of most instrument functions
by means of PC.
Additional program is attached to the RX-25. 3.9 software which enables
loading of upgraded versions of MagPro software to PC. This operation
is realized by RS 232 port.
Important: - the probe is extremely delicate part of the teslameter, please
take care during using it. Please do not plug-in probe to the teslameter
when it is on.
