Two channels, -0.3V to 3V, input impedance 4k ohms to a 3V bias, (models SKU204+ *) . | Two channels, -0.3V to 3V, input impedance 4k ohms to a 3V bias, (models SKU204+ *) . At the time of writing, as a workaround to a bug with dual channels, apply the input to both channels, only a mono reading is available. | ||
(* A small number of pre-production laptops were built with -3V to +3V input range and input impedance 1k ohm to a +3V bias, eg. model SKU199. Turtle Blocks V141 and previous is correctly calibrated for these laptops but not for production laptops) | (* A small number of pre-production laptops were built with -3V to +3V input range and input impedance 1k ohm to a +3V bias, eg. model SKU199.
