Comment(by walter):

 Resistance sensors are working OK? not ac coupled?

 And you are using a voltage block, not a voltage2 block (which should no
 longer appear on XO1 as per a recent patch)

 http://git.sugarlabs.org/turtleart/mainline/commit/536e8bc53fc83fcc051ae79859bd6912e2260af0

 From audio_sensors.py:
 elif self.hw == XO1:
             self.PARAMETERS = {
                 SENSOR_AC_BIAS: (False, True, 40, True),
                 SENSOR_DC_NO_BIAS: (True, False, 0, False),
                 SENSOR_DC_BIAS: (True, True, 0, False)
                 }

 For both Resistance (DC_NO_BIAS) and Voltage (DC_BIAS) the first parameter
 (DC_MODE) is True, hence my first question above.
