accuracy values represent spread from nominal. Unless otherwise stated represents percentage full scale value. (ii) represents percentage reading stated units (iii) Represents valid thermistor temperature range used measuring Cold junction temperature. Slight internal warming from unit means that temperature above ambient. (iv) Average taken over second time frame. Acquisition defined complete refresh electrical sensor value including readings compensate gain offset errors. Cold junction accuracy includes thermal tracking error, temperature measurement error linearisation error. This should added individual thermocouple accuracy overall accuracy value. (vi) represents percentage full scale value. (vii) Input measured correctly within small margin outside normal range. This bipolar (+/-) electrical inputs. Current inputs that down zero under-range otherwise other sensor inputs have over/under-range margin. (viii) This extended with suitable buffering (ix) There internal pull down resistor -2.5V.
