4294A Setup
Before beginning measurements, you should perform the adapter setup. The
following procedure shows adapter setup for the 42942A. Also refer to the
operation manual of the 4294A for more information on adapter setup.
CAUTION
When handling the 42942A, care must be taken not to give it any mechanical
shock, which may damage the adapter. Never give any mechanical shock to the
upper face with the 7-mm connector’s mouth. Also, do not place the 42942A with
the upper face down on a hard surface.
NOTE
If the ambient temperature deviates by more than 5
°
C from the temperature in
which the adapter setup was done, it is recommended that you again perform the
adapter setup in the ambient temperature.
