(conductivity
standard) Selection of the conductivity standard used to calibrate the
conductivity cell. 8 standards are available:
Figure 42: Conductivity standards available in the TIM870
The TIM870 determines the cell constant from the conductivity values
of the standard which are saved versus temperature.
Access:
1. From the Electrode window, press 4 .
