As there is no potentiometer, the output range has been slightly enlarged to cover maximum values even in the worst case.Typical output range (without component tolerances): W605: W615: W625:0.26 V…+ 10.36 V (instead of 0…+ 10 V) - 0 mA…+ 21.4 mA (instead of 0…+ 20 mA) - 10.62 V … 10.36 V (instead of - 10…+10 V)This range is broken down on a 10 bit scale (1024 steps), as before. The result is the following LSB resolution: W605: W615: W625:1 LSB = 10.38 µV 1 LSB = 21.7 µA 1 LSB = 20.75 µVWith this balance the nominal range (0...10 V) is now scaled 0...1023, making it possible for the output value not to change on an increase of 1 LSB.Hardware Manual for the PCD2.M5 Series│Document 26/856; Version EN 09│2012-01-256-76
