1762-IT4 Repeatability at 25 °C (77 °F)
(1) (2)
(1) Repeatability is the ability of the input module to register the same reading in successive measurements for the
same input signal.
(2) Repeatability at any other temperature in the 0…60 °C (32…140 °F) range is the same as long as the
temperature is stable.
