Calibration Functions, Menu 7.0
The calibration functions of the flowmeter are contained in menu level 7.0. These functions are not
needed for general operation and setup of the flowmeter. With the exception of 7.1, Show Delta R, these
functions should be used only after consultation with a factory service representative. Menu level 7.1
displays the RTD resistances and can be compared to calibration resistances. This is useful for
troubleshooting problems and is addressed in Chapter 6, Troubleshooting.
To view RTD resistance values:
1. Press 7, the Calibration option.
2. Press 1, the Show Delta R option.
3. Press 1, for raw dR, 2 for TCdR or 3 for AIdR
