19. to measure temperature the RTD sensing element must be connected through the IP67 rated M8 connector P N 3953 provided with your RTD100 module Since the temperature measurement is based on the sensing element resistance any other resistance in the system lead wire connections etc may be added to the measurement circuit and will result in mea surement error Care must be taken to eliminate the effects of any unwanted resistance in order ensure the best possible measurements The three wiring methods are 2 wire In the 2 wire method the sensor resistance measurement includes the lead wire resistance This method is typically used only when lead wires are very short or when high measurement ac curacy is not required In the 3 wire method two lead wires connect to one side of the RTD sense element while the third lead connects to the other side The two adjoining lead wires cancel each other out allow ing the nVision to read the RTD sense element without the associated lead resistance measure ment error This self canceling resistance value is also subtracted from the other leg with the assumption that the two are equal Your nVision is also capable of 4 wire measurements The fourth wire allows the other side of the lead wire to self cancel independently thus reducing your measurement uncertainty to a greater level CRYSTALCONTROL It is also necessary to ensure that your nVision is properly configured in CrystalControl t
