5.2.1 Teslameter FM 302 The Teslameter FM 302 has a 4 ½ digit display and three measuring ranges. The sensitivity of the ranges depends on the used probe and differ in factor 10 and factor 100. The polarity is displayed by the sign. The displayed unit can be switched between Tesla, Gauss, Oersted and A/m.

The control software do not just allow to display the measured values of the FM 302 but also allows to save them into a log file. For this two different modes are offered. In the mode “single value logging” single measured values can be saved with a key press (mouse or keyboard).

Teslameter FM 302, the device can be mounted to a top hat rail. For release the locking bar has to be pulled up with a screw driver. 6.3.1.4 Power Switch On the left side of the Teslameter FM 302 is a sliding switch to switch it on and off. 6.3.1.5 Keypad The Teslameter FM 302 has a keypad which allows to control major device functions.
6. Operation 6.3.1.6 Display The Teslameter FM 302 has a two-line LCD display. After power on the device initializes itself. During that the display shows the manufacturer and device name. Figure 4 Display of Teslameter FM 302 Afterwards the display shows the device number / serial number and the firmware version.
See also section 6.3.1.9 Key “gain” – Measuring Range to change the measuring range. In the lower left the state of the power supply of the Teslameter FM 302 is displayed. A full battery symbol denotes, that the Teslameter FM 302 is running on battery and that the voltage of the battery is sufficient to power the device.
If the Teslameter FM 302 runs on battery as power supply and if the battery is nearly empty, instead of the unit, the empty battery symbol is shown in lower right.
Figure 12 Display error message offset out of range To reset the compensation to zero, the key “zero” has to be pressed a second time while the compensation process is running. The FM 302 confirms the reset of the compensation with the message “reset zero to midscale”.
The chosen range determines the sensitivity of the display and the analog output. See also section 6.3.3.12 Command “gain” for controlling the measuring range via the USB interface. Projekt Elektronik MESS - UND REGELUNGSTECHNIK GMBH Page 27...
Figure 15 Display in relative measurement relative value = absolute value – reference value If the key is pressed again, the Teslameter FM 302 switches back to the measuring mode absolute measurement. The relative measurement has no influence on the analog output of the Teslameter FM 302.
Each time the measuring time has passed a new measured value is available and printed out at the display. The internal sample rate of the Teslameter FM 302 is 10 Hz. From the samples taken during the measuring time, the measured value is computed.
The setting of the measuring time has no influence on the analog output of the Teslameter FM 302. The analog output always delivers the unfiltered absolute signal with full bandwidth. See also section 6.3.3.13 Command “inttime” or “time” for extended possibilities for controlling the measuring time via the USB interface.
The setting of the filter length has no influence on the analog output of the Teslameter FM 302. The analog output always delivers the unfiltered absolute signal with full bandwidth. See also section 6.3.3.10 Command “filter” for extended possibilities for controlling the measuring time via the USB interface.
USB 2.0. To this port a USB cord with type B plug can be connected to connect the Teslameter FM 302 with a PC. A suited cable is included in delivery (see also section 5.3 Items Supplied). Via the USB interface the Teslameter FM 302 may be controlled and the measured values read out (see also section 6.3.3 USB Interface).
A cable with BNC connector has to be used. To control via USB interface the FM 302 has to be connected to the computer. The connection also can be made to a USB hub. Therefore an ordinary cable with USB-B connector has to be used.
6. Operation To power the device externally a 9 V power supply can be uses. A suitable power adapter may optionally ordered with the FM 302. Alternatively the device can be powered via the USB connection. See also section 6.3.2.2 Power Supply.
− The battery life (operating time) is approx. 20 hours, depending on the probe type. 6.3.2.4 Power Adapter Operation − Open the case (printed lettering up) and remove the Teslameter FM 302 and the power adapter. Projekt Elektronik MESS - UND REGELUNGSTECHNIK GMBH...
− Plug the power adapter into a 230 VAC mains socket. − Plug the small plug from the power adapter into the 9 V-power connector at the lower left side of the Teslameter FM 302 (see section 6.3.1.19 Power Connector).
To, in contrast to the Teslameter FM 205, show not only the unit Tesla but also Gauss, Oersted and A/m at the Teslameter FM 302 an extension of that coding was necessary. Since September 2011 the AS- active-probes have the extended coding.
6.3.3 USB Interface 6.3.3.1 General The USB interface of the Teslameter FM 302 is realized with the FT232R, a USB-to-serial converter from Future Technology Devices International Ltd. (FTDI, http://www.ftdichip.com/). That means, that the Teslameter FM 302 creates a virtual serial port after it has been connected to a PC.
6. Operation 6.3.3.4 Configuration of the Virtual Serial Port To communicate with the Teslameter FM 302 the virtual serial port has to be configured as follows. baud rate 9600 data bits parity none stop bits flow control 6.3.3.5 General about Commands The Teslameter FM 302 has a simple command structure consisting of the command name followed by one optional parameter.

Figure 23 Control software FM 302 Control 6.3.4.1 General Description Included in delivery is a control software for the Teslameter FM 302. The software allows to control all settings of the Teslameter via the PC. Thereby the software not only allows to control the settings accessible via the keypad of the device, but offers the complete range of functions which are possible with the commands via the USB interface.
The software FM 302 Control is delivered with a ClickOnce installation routine. To install the software the setup.exe has to be executed which can be found at the CD in the folder D:\FM 302 Control\ and there in the subfolder with the current version. The installation runs automatically and starts FM 302 Control afterwards.
(e.g. by clicking into an other field). The input field will be updated with the value actually confirmed by the FM 302. For the exact function and the value range of the parameters see the descriptions in section 6.3.3 USB Interface.
The scale of the amplitude axis is given by the connected probe and the selected sensitivity of the FM 302. It covers the full range of values possible in the set configuration. In measuring mode relative measurement the baseline is moved corresponding to the set reference value.
The control software not only permits to display the measured values of the FM 302 but also to save them into a log file. There are two different modes and two different file formats to chose from. The selection can be made in the section “logging”.
This mode is suitable for manual controlled measurements where a number of single values has to be measured. Figure 30 Single value logging Projekt Elektronik MESS - UND REGELUNGSTECHNIK GMBH Page 54...
With the button “clear log” the existing log can be erased. With the button “save loge” the recorded log can be stored. The log is kept in the program so it can be continued afterwards. Projekt Elektronik MESS - UND REGELUNGSTECHNIK GMBH Page 55...

Figure 52 Usage of AS-active-probe with FM 302 Also all extended possibilities of the Teslameter FM 302 like calibrated analog output, control via USB interface or power supply with power adapter are usable in that way. Further details can be found in section 6.3.2 Usage of The Teslameter FM 302.
The pin configuration of the probe is shown in the graphic below. All other pins are reserved for future use ore are only relevant in combination with the Teslameter FM 302. These pins have to remain unconnected. Figure 54 Pin configuration AS-probe at ±3 V Like shown in the inner structure schematic the output signal at pin 1 is always referred to the ground signal at pin 2 and 3.
Now one can assume that the magnetic field is sufficient shielded. With the “zero” key of the Teslameter FM 302 (see section 6.3.1.7 Key “zero” – Offset Compensation) the display may set to zero in the most sensitive range.
The linearity curve serves as a test record. The following illustration shows an exemplary set of linearity curves: ∆B [ mT ] [ T ] 0,2 % ±0,2 mT 0°C 20°C 40°C Figure 57 Typical linearity curves Projekt Elektronik MESS - UND REGELUNGSTECHNIK GMBH Page 70...
