If traces show on the display and Hold shows on the status line at the top of the display, push  to reset the Test Tool. 17. Use the EDIT FIELD function on the Calibrator to slowly decrease the voltage in 0.1 V steps until the Test Tool triggers and the traces show on the display. 18. Verify that the voltage on the Calibrator is between +0.5 V and +1.5 V when the Test Tool triggers. 19. To repeat the test, start at step 15. 20. Set the Calibrator to Standby. 21. Push to clear the display. 22. Set up the Test Tool to test Input B: a. Push . b. Push  to open the SCOPE SETTINGS menu. c. Make these selections: • Trigger Input: B • Update: Single • Type: Normal • Waveform: Normal 23. Push  to setup the Test Tool to test the positive slope. Use  to set the trigger level to +2 divisions. For positive slope triggering, the trigger level is the top of the trigger icon. 24. Set up the Calibrator: a. In the Scope Volt mode, supply 1.1 V DC. b. Push . 25. Verify that traces do not show on the display of the Test Tool and that Waiting shows on the status line at the top of the display.
