OHM Ω Measure the resistor value (Ω) of a resistor connected to the red and black 4-mm banana jacks.

DIODE Test a diode that is connected to the red and black 4-mm banana jacks. The red banana jack is the high input while the black one is the low. The result is displayed as the forward or reverse voltage of a diode.

CONTINUITY Ω Detect an open or closed circuit that is connected to the red and black 4-mm banana jacks. A beeper draws your attention when the circuit is closed.

°C PROBE EXT.mV Detect a temperature in degrees Celsius with a Temperature probe (optional) that is connected to the red and black 4-mm banana jacks.

°F PROBE EXT.mV Detect a temperature in degrees Fahrenheit with a Temperature probe (optional) that is connected to the red and black 4-mm banana jacks.

ACCESSORY (mV) EXT.mV Measure millivolts with an accessory that is connected to the red and black 4-mm banana jacks.
