Adapter Setup Procedure for the 42941A
Perform the adapter setup for the 42941A Impedance Probe in accordance with the
following procedure (the operation manual for the 42941A also describes the adapter setup
procedure).
NOTE
Adapter setup should be performed at an ambient temperature as close as possible to the
temperature in which the device measurement will actually be made.
If the ambient temperature for your measurement is outside the range of
±
5
°
C from the
adapter setup temperature, it is recommended that you perform adapter setup again at the
appropriate temperature.
It takes a few minutes to complete each setup data measurement.
During each data measurement, the message “WAIT--MEASURING ADJUSTMENT
KIT” is displayed in the instrument state area in the LCD's upper-left side.
