Except for 2-3 exception, the Newport 842-PE doesn't have real getter functions, but it has many setters. But is has a function (sta) that read device status for a lot of parameters. The previous file do a fake getter/setter.

def status
returns a dict where the key/value pairs correspond to each device parameter.

At device initialisation, the device's configuration is read and stored in self.DeviceStatus

The getter scale just read corresponding parameter in self.DeviceStatus and return it.

The setter scale actually write to the device to change its state.
