General Safety Information

The following general safety precautions must be observed during all phases of

operation of this instrument. Failure to comply with these precautions or with

specific warnings elsewhere in this manual violates safety standards of design,

manufacture, and intended use of the instrument. Keysight Technologies assumes

no liability for the customer’s failure to comply with these requirements.

WARNING

– Remove all unused scope (oscilloscope) probes, DMM (digital

multimeter) test leads, or USB cable.

– Do not connect the DMM test leads and scope probes at the same time.

– Disconnect the scope probe from the instrument before using the DMM

functions.

– Disconnect the DMM test leads from the instrument before using the

scope functions.

WARNING

To avoid electrical shock or fire during battery replacement:

– Disconnect test leads, probes, power supply, and USB cable before

opening the case or battery cover.

– Do not operate the instrument with the battery cover open.

– Use only specified insulated probes and test leads.

– Use only the 10.8 V Li-Ion battery pack supplied with the instrument.

WARNING

To prevent fire or injury:

– Use only the designated AC/DC adapter and test leads supplied with the

instrument.

– Observe all ratings and markings on the instrument before connecting to

the instrument.

– When performing measurements, ensure that the right safety and

performance ratings of instrument and accessories are used.
