Options available in Operator mode are limited to those designed into the test by the engineer. Engineer mode: This mode is used by quality assurance and engineering personnel who design and supervise the individual measurements and tests that make up overall product testing. Pass/fail limits: Pass/fail limits can be created in various ways: - Setting an envelope in a specified range above and below a referenced microphone - Statistical analysis of the measurements of a batch of microphones - Using the cursor to draw any arbitrary limits Once a pass/fail limit is created, it can be modified manually by the use of a cursor.   Operator mode-main menu commands : - Select test - Do test - Set delay - Set amp level - Graph display (on-off) - Saved for future commands - Statistics - Keyboard/barcode input - Stop test - Quit Selections 3, 4, 7 and 8 can be enabled or disabled at the option of the engineer.
