No equivalent command is available.
However, the same functionality can be
obtained by setting the limit mode to the
absolute mode and then setting up each BIN
with the same command as in the tolerance
mode.

*1.For the 4288A, this setup is commonly applied to the measurement parameters. There-
fore, the command to set up each measurement parameter is given here.
*2.The limit is specified as a percentage of the measurement range. Thus, for the same
limit (%) value, the 4278A and the 4288A may show different boundary values where
Low C is actually detected if the measurement ranges are not identical.
