Testing for Continuity

• You can set the beeper to sound and the backlight to flash as a 
continuity indication whether the circuit-under-test is less than (short) 
or more than or equal to (open) the threshold resistance.
• The continuity function detects intermittent shorts and opens lasting 
as short as 1 ms. A brief short or open causes the multimeter to emit a 
short beep and flash.
• You can enable or disable the audible and visual alert via the Setup 
menu. See “Changing the continuity test alerts” on page 93 for more 
information on the audible and visual alert options.
