------------------------------------------------------------------------


### \_\_init\_\_()


Initialize FH55.


Usage

``` python
__init__(
    interface,
    timeout=1000.0,
    **kwargs,
)
```


#### Parameters


`interface: str`  
The ip andress and port where the device is located. e.g. TCPIP::192.98.143.1::5025::SOCKET

`timeout: int = ``1000.0`  
(Default = 1e3 ms) The timeout of the ethernet connection.

`**kwargs`  
Keyword arguments passed to the VISAdevice constructor.


------------------------------------------------------------------------


### getField()


Return magnetic field in T.


Usage

``` python
getField()
```


units = \["mT","T"\].


------------------------------------------------------------------------


### getMode()


Return the AC/DC mode.


Usage

``` python
getMode()
```


------------------------------------------------------------------------


### getTemp()


Return temp in degree celsius.


Usage

``` python
getTemp()
```


------------------------------------------------------------------------


### reset()


Reset the FH55 using the RESET command.


Usage

``` python
reset()
```


This resets all peak (max/min) settings. RESET returns a "OK".


------------------------------------------------------------------------


### setFilter()


Set the filter on or off.


Usage

``` python
setFilter(filter_status)
```


#### Parameters


`filter_status: str`  
Status of the filter, either "ON" or "OFF". Corresponds to 1=ON, 0=OFF in the device commands.


------------------------------------------------------------------------


### setMode()


Set the operation mode.


Usage

``` python
setMode(mode)
```


#### Parameters


`mode: int`  
The operation mode: 0 = DC mode 1 = AC mode


------------------------------------------------------------------------


### setRange()


Set the measurement range based on the current field strength.


Usage

``` python
setRange()
```


Automatically selects the appropriate range for the Hall probe based on the measured field magnitude. Range selection criteria: - Range 1: \< 30 µT - Range 2: \< 300 µT - Range 3: \< 3 mT - Range 4: \< 30 mT - Range 5: \< 300 mT - Range 6: \< 3 T

Prints an error message if the field is outside of valid ranges.
