Continuity tests
Set up your multimeter as shown in the figure below to per-
form continuity tests. Press   to switch to the continuity 
test function (  is shown on the display).
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. 
Press   to switch between short ( ) and open ( ) 
states for checking NO (normal open) and NC (normal close) 
contacts.

The continuity function detects intermittent shorts and opens 
lasting as short as 1 ms. A brief short or open causes the multi-
meter to emit a short beep and flash.
