2.Touch the Procedure field, then select Ext Trig Null from the pop-up menu.

3.Touch the Start field and follow the instructions on the display.

4.At the conclusion of the ext trig null calibration, remove the cables from the rear of the module.

Messages will be displayed as each calibration routine is completed to indicate calibration has passed or failed. The resulting calibration factors are automatically stored to nonvolatile RAM at the conclusion of each calibration routine.

This is the conclusion of the calibration procedures. The display should now look similar figure 4-5.
