6.2 Calibration, scrolling method

6.2

Calibration, scrolling method

The 4 and 20 mA calibration values can be selected where reference levels, either from the

material in the vessel or from a target, cannot be provided. This method can also be used to

trim the output levels obtained by the Calibration: reference method (Page 20)

To change the stored calibration value, obtain the 'c 4' or 'c 20' display. The calibration value

may be increased by pressing the "20" key or decreased by pressing the "4" key. When the

display has scrolled to the desired value, stop pressing the key. The display automatically

reverts to the Run mode (6 secs).

Note

For faster scrolling, hold the key, and release it when the appropriate value is shown.
