To change whether the beeper sounds on shorts or opens, press the softkey labeled Menu. Move the menu selector to the menu item labeled Beeper and press the softkey labeled Short/O.... This beeper selection, Beep on Short or Beep on Open, is displayed just above the continuity indicator. The continuity beeper is always enabled when continuity mode if first entered. To enable or disable the beeper for continuity, press the softkey labeled Menu. Move the menu selector to the menu item labeled Beeper and press the softkey labeled Beeper. The status of the continuity beeper is displayed to the right of the resistance reading with j when enabled and i when disabled. This setting is independent of the Meter's beeper enable/disable setting in the setup menu. Toggle between the continuity and ohms functions by pressing softkey F3, which is always labeled with the alternate function. True-rms Digital Multimeters Making Measurements 33
