130 34405A User’s and Service Guide
6 Specifications
These specifications apply when using the 34405A 
multimeter in an environment that is free of electromagnetic 
interference and electrostatic charge. 
When using the multimeter in an environment where 
electromagnetic interference or significant electrostatic 
charge  is present, measurement accuracy may be reduced. 
Particularly note:
• The voltage measurement probes are not shielded and can 
act as antennas, causing electromagnetic interference to 
be added to the signal being measured.
• Electrostatic discharges of 4000 V or greater may cause 
the multimeter to temporarily stop responding, resulting 
in a lost or erroneous reading.
