In oscilloscope mode, observe the specified ×1 and ×10 probe input limits and ensure the instrument's probe setting matches the physical probe attenuation.
Never connect the current input directly across a voltage source.
Disconnect circuit power and fully discharge capacitors before resistance, capacitance, continuity or diode testing.
Always inspect probes and test leads before use and never exceed the marked limits of the instrument or accessories.
