4.3.5 Resistance Measurement (Ω)
CAUTION
To avoid damage to instrument
Turn off the power to the circuit under test before starting measurement in order to prevent any
excessive voltage from being applied to the instrument.
1) Turn the function switch to the “ Ω ” position.
2) Plug the testing leads into the input terminals.
3) Connect the testing leads to the circuit under test and then read the value
when it stabilizes.
