Resistance Measurements 20 Because the current flows through the circuit for resistance measurements. See Figure 7. The Multimeter sends a small current through iFlex all possible paths between the probes. Figure 7. 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.

Figure 9. See Figure 9. iFlex iFlex OL shows on the display when the circuit is sensed. 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. 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.
