PROTECTION LIMITS
To avoid instrument damage and the risk of electric shock, do not exceed any of the Protection Limits defined in the
following section.
ENSURE TEST LEAD IS USED AS SPECIFIED
If the Test Leads are used in a manner not specified by Keysight Technologies, the protection provided by the Test
Leads may be impaired. Also, do not use a damaged or worn Test Lead. Instrument damage or personal injury may
result.
MEASURING VOLTAGES GREATER THAN 30 VRMS, 42 VPK, OR 60VDC
Measuring voltages greater than 30 Vrms, 42 Vpk, or 60 Vdc is always hazardous. ALL multimeter terminals must be
considered as hazardous whenever inputs are greater than 30 Vrms, 42 Vpk, or 60 Vdc are connected to ANY input
terminal. Regard all terminals as being at the same potential as the highest voltage applied to any terminal.
AC POWER CORD
Removal of the AC power cord is the disconnect method to remove power from the instrument. Be sure to allow for
adequate access to the power cord to permit disconnection from AC power. Use only the Keysight specified power
cord for the country of use or one with equivalent ratings.
DO NOT EXCEED MEASUREMENT LIMIT
Do not exceed any measurement limits defined in the specifications to avoid instrument damage and the risk of
electric shock.
OPERATING IN REMOTE MODE
When operating in remote mode, measurements will be triggered by remote computer and will not be updated
continuously on the instrument display. Always refer to the remote computer for actual measurement.
CLEAN WITH SLIGHTLY DAMPENED CLOTH
Clean the outside of the instrument with a soft, lint-free, slightly dampened cloth. Do not use detergent, volatile
liquids, or chemical solvents.
PRESENCE OF AMBIENT ELECTROMAGNETIC (EM) FIELDS AND NOISE
Degradation of some product specifications can occur in the presence of ambient electromagnetic (EM) fields and
noise that are coupled to the power line or I/O cables of the instrument. The instrument will self-recover and operate
to all specifications when the source of ambient EM field and noise are removed or when the instrument is protected
from the ambient EM field or when the instrument cabling is shielded from the ambient EM noise.
CAUTION WHEN WORKING WITH VOLTAGES ABOVE 30 VRMS, 42 VPK, OR 60 VDC
Use with caution when working with voltages above 30 Vrms, 42 Vpk or 60 Vdc. These voltages pose a shock hazard.
CAUTION WHEN CONNECTING OPEN LEADS TO THE HI SENSE AND LO SENSE TERMINALS
When not in use, the Hi sense and Lo sense terminals will not be connected. Do not connect open leads to these
terminals or disconnect these terminals with an external device.
