Multimeter (220-0179) Continuity Check Faxback Doc. # 6270 The continuity check function helps you check for shorted or open electrical circuits. 1. Set the function switch .))) CONT. OL,.))) , and ohms appear on the display. The range automatically sets to 400ohms. Caution: Do not connect the test leads to a source of voltage when you set the function switch to .))) CONT. Doing so might damage the multimeter. 2. Connect the probes to the circuit to be checked. The display shows the actual resistance value. If the circuit resistance is 50 (+/-30) ohms or less, the buzzer sounds continuously to indicate there is sufficient continuity. Note: During continuity checks, when there is not a specific resistance connected across the test leads, it is normal for the display to show OL (over-load indication) because the multimeter detects it as an infinite resistance.
