Resistance (Ω)
Used for “ohming out” a compressor. A 0.01Ω resolution is useful to
test the resistance between the terminal poles because the values are
typically very low. Resistance is default test in this switch position. For
best practice, use a megger (Fieldpiece SMG5) to measure motor winding
insultion to ground.

Perfect for checking isolated fuses, use the continuity function to test
whether a circuit is open (no beep, no green LED) or closed (beep and
green LED). Press SELECT once to enter Continuity mode.
