ID
CAUTION
The ID jumpers MUST correspond to the matrix configuration set by the
CONFIG jumpers in the following step. The instrument firmware functions
based on the ID it detects from the (ID) jumper positions and assumes the
CONFIG jumpers are set accordingly.
NOTE
In a high temperature-high humidity environment, salt and oil contaminants
transferred from the fingertips to the moveable CONFIG jumpers can affect the
34934A’s published DC Isolation specification if adjacent jumpers are in physical
contact with each other. In applications where DC (channel to channel) isolation >
10 GΩ is required, use clean cotton gloves when handling the CONFIG jumpers.
If cotton gloves are not available, clean the plastic jumper surfaces using a
cotton cloth and 91% isoprolyl alcohol after handling.
