MAX / MIN Memories

The 42280A records and displays the highest and lowest temperature and
RH readings. Short press the MAX/MIN button to step through the highest
readings recorded (MX is shown), lowest readings recorded (MN is shown),
and back to real time readings (MX and MN indicators switch off).
Figure 5.1 Maximum and Minimum readings display showing the MX and MN indicators.
To clear the memories, long press the MAX/MIN button until MX/MN flashes
on the display.
The Average, Standard Deviation, and Mean Kinetic Temperature (MKT) cal-
culations are also recorded, but shown only on the PDF log report that the
42280A generates. See Section 6 for details.
