Cold Junction Compensation |
Connection terminal for 4 thermocouples, thermal embedded Pt1000 temperature sensor 2 terminals each module required (8
thermocouples) Cold Junction Compensation will not be
adjusted in combination with the module Q.bloxx A104. Because of a random exchangeability, the
maximum deviation is higher than with an adjusted combination with the cold
junction compensation terminal (see page 3). |
