Select the µA signal measuring range for 3-electrode cells
and membrane sensors:
70 µA, 100 µA, 200 µA, 1000 µA
for Micro 2000 and Deox 2000: 10 µA, 100 µA, 1000 µA

value, either
CAN external or analog (mA input 1).
Only applicable is using a CI-N-sensor.
Setting the connected measurement signal:
0 – 20 mA, 4 – 20 mA, 0 – 10 V, CAN external
power supply should be arranged in accordance with this setting
(see 9. “Wiring Diagrams”)
Factor for adapting an external input signal:
0.1 – 4.0
Adjustment of the reference temperature for the conductivity
measurement:
20°C / 25°C
Display => NaCl in g/l / NaCl in % / TDS in g/l / off
TDS factor =>0.4 – 1.0 (if TDS display is active)
TDS:
Total Dissolved Solids = filtrate dried solid matter content in g/l
The TDS factor depends on the composition of the sample water
and must be determined for each water type.
