Page 31: Calibration Log
If during this 8 seconds interval digital activity is detected on the RS485 line it will switch to digital communication. Else it will remain in analog operation. The calibration and programming via PC gives additional possibilities concerning the signal calibration and is straight forward. 07/2017 - 4001970202 - MA OPTISENS TUR 2000 R01 en www.krohne.com... -
Page 32: Communication Protocol
After 2 seconds from switching the sensor on, the current will provide for 8 seconds a fixed current value depending of the selected scale: 8 mA for 4.000 NTU scale 12 mA for 40.00 NTU scale 20 mA for 400.0 NTU scale www.krohne.com 07/2017 - 4001970202 - MA OPTISENS TUR 2000 R01 en... -
