Beeper Control

Normally, the multimeter will emit a tone whenever certain conditions are met from the front panel. For example, the multimeter will beep when a stable reading is captured in reading hold. You may want to disable the front-panel beeper for certain applications.

•When you disable the beeper, the multimeter will not emit a tone when:

1)a new minimum or maximum is found in a min–max test.

2)a stable reading is captured in reading hold.

3)a limit is exceeded in a limit test.

4)a forward-biased diode is measured in the diode test function.

•Disabling the beeper has no effect on the tone generated when:

1)an error is generated.

2)the continuity threshold is exceeded.

3)you turn off the front-panel menu.

Turning off the beeper does not disable the key click generated when you press a front-panel key.

•The beeper state is stored in non-volatilememory, and does not change when power has been off or after a remote interface reset. The beeper is enabled when the multimeter is shipped from the factory.
