To measure ac or dc voltage:
To measure resistance or continuity:
If the resistance is < 30 Ω, continuity is indicated by a beeper continuously sounding. If the display reads OL, the circuit is open or the resistance being measured is greater than the meter’s resistance range.
To measure frequency (on the Fluke 381):
To measure capacitance (on Fluke 370 series clamp meters)
