The accuracy values represent +/- spread from nominal. Unless otherwise stated '%' represents the percentage of full scale value. (ii) '%' represents percentage of reading in stated units (iii) Represents the valid thermistor temperature range used for measuring Cold junction temperature. Slight internal warming from the unit means that temperature is 3 or 4°C above ambient. (iv) Average taken over a 1 second time frame. Acquisition defined as complete refresh of electrical sensor value including readings to compensate for gain and offset errors. (v) Cold junction accuracy includes thermal tracking error, temperature measurement error and linearisation error. This should be added to the individual thermocouple accuracy to get an overall accuracy value. (vi) '%' represents percentage of full scale value. (vii) Input is measured correctly within a small margin outside the normal range. This is 7% for bipolar (+/-) electrical inputs. Current inputs that go down to zero do not under-range otherwise all other sensor inputs have a 7% over/under-range margin. (viii) This may be extended with suitable buffering (ix) There is an internal 10M ohm pull down resistor to -2.5V. This is only significant for high source impedance mV inputs. (x) 50mV and 100mV respectively. (xi) 1V and 10V respectively. (xii) With respect to Pin 1 or Pin 5.
