６－６ Continuity Check (400Ω range fixed)

※ The continuity check mode is enabled by pressing the mode

selector switch on resistance range. "

" is indicated on the

display to show the instrument in the continuity check mode. The

buzzer beeps, if the resistance under test is 20.0Ω or less.

 DANGER

●Never use the instrument on an energized circuit.

● Do not make measurement with the battery compartment cover

removed.

● Keep your fingers and hands behind the barrier during

measurement.

①Set the function selector switch to the " Ω" position.
