See Figure 7. Figure 7. Because the current flows through the circuit for resistance measurements. Resistance Measurements 20 279 FC Users Manual Resistance Measurements XW Warning To prevent possible electrical shock, fire, or personal injury, disconnect power and discharge all paths between the probes, the resistance measured is the total resistance of all high-voltage capacitors before you measure resistance, continuity, capacitance, or a diode junction. The Multimeter sends a small current through iFlex all possible paths between the probes.

Continuity Tests 22 The continuity test uses a beeper that sounds when a closed circuit is open. The beeper lets you measure resistance, continuity, capacitance, or a diode junction. iFlex iFlex OL shows on the display when the circuit is sensed. Figure 9. See Figure 9. 279 FC Users Manual Continuity Test XW Warning To prevent possible electrical shock, fire, or personal injury, disconnect power and discharge all high-voltage capacitors before you do continuity tests without the necessity to look at the display.
