maximum values set for the analog meter, a warning message is

Note
HP EPM-441A User's Guide
The analog display does not indicate as much measurement data
as the digital display. That is, it does not indicate when duty cycle,
range hold, offset or relative mode are enabled. In addition, it does
not indicate if the measurement is within the test limits if any are
set.
