New description:

 XO-4 B1 (preproduction) SKU292
                self.voltage_gain = 0.0004073
                self.voltage_bias = 1.6289
 Range 0.17V to 3.08V

 resistance, both inputs connected:
             elif self.hw in [ XO4]:
                 if avg_buf < 6629:
                     self._resistance[channel] = \
                         1.0 * ((50000000 / (6629 - avg_buf)) - 3175)
 range 0 to inf ohms



 XO-1.75 (production) SKU203
 self.hw reports as xo1 so the model detecting logic is not working
 (sug0.94 OS883)
 THAT MEANS IT IS INITIALISING AS XO1, CALIBRATION AFFECTED
                 self.voltage_gain = 0.000101
                 self.voltage_bias = 1.371
 Range 0.01V to 3.01V

 resistance both inputs connected

                if avg_buf < 15740:
                     self._resistance[channel] = \
                         1.0 * ((48000000 / (15740 - avg_buf)) - 1640)

 range 0 to inf
