11.2 Sel. Display & Start (Display Type Selection)
Fig. 11 - 3
Menu for display type selection
1 Resistance
Display of ohmic resistances with four digits after the decimal point
2 Temperature
Display of temperatures with three digits after the decimal point
3 Resistance Stat.
Display of resistance statistics: Display of resistances, mean values and
standard deviations of the N last values. N can be set with the arrow keys.
4 Temperature Stat. Display of temperature statistics: The current temperatures are displayed
with four digits after the decimal point, the mean values and the standard
deviations are displayed with five.
5 R1/RREF, R2/RREF Display of the ratios of sensor resistance to reference resistance in large
digits.
6 R1/R2, R2/R1
Display of the ratios of the two sensor resistances in large digits.
