Display hold
can be selected by pressing “Hold” button (10).
11) Take off the protective tube of the Hall probe, position the Hall probe
(14) on the surface of the measuring object (such as permanent
magnet), and read the display value (measuring value and pole
display “N” or “S“, N for north pole, S for S pole).
Note:
The magnetic pole of the measuring object is N pole if the
display show
s “N” while the label side of a transverse Hall probe is
faced towards the surface of the measuring object. In this case you
can read the mark SONNECY of the Hall probe (see picture below).
The magnetic pole of the measuring object is N pole if the display
shows “N” when the end of an axial Hall probe is put on the surface of
the measuring object.
12) After the measurement please put the protective tube on the Hall
probe in order to protect the Hall element and switch off the power
13) The Hall probes delivered are calibrated by using an identical
reference Gaussmeter CYGM99A. Therefore all of our Hall probes
are compatible for the Gaussmeter CYGM99A.
9. Control with PC
1) Connect the measuring instrument (9) to PC via USB cable and install
the CH340G driver for new detected device. This measuring device is
identified as a serial port COMx.
2) The measuring instrument has a full duplex serial port, which is
configured with 1MHz baudrate, no parity check and one stop bit.
User can send following 1 byte ASCII code to select corresponding
functions.
No.
