WARNING
• Plug the probe or test leads to instrument before connecting to any
active circuit for testing. Before disconnecting from instrument,
remove scope probe or test leads from active circuit.
• Do not connect the ground wire to voltages higher than 42 Vpeak (30
Vrms) from earth ground if either the DMM COM or the OSC COM is
connected to the DUT or is being accessed by the user.
• Do not expose the circuit or operate the instrument without its cover
or while power is being supplied.
• Do not use exposed metal BNC or banana plug connectors. Use only
the insulated voltage probes, test leads and adapters that come with
the instrument.
• Do not supply any voltage when measuring resistance or
capacitance in multimeter mode.
• Do not operate the instrument if it does not operate properly. Have
the instrument inspected by qualified service personnel.
• Do not operate the instrument in wet or damp environments.
• Do not operate the instrument in any environment at risk of
explosion. Do not operate the product in the presence of flammable
