5.12 Min/Max Log
The Min/Max log registers are supported only for compatibility with other models of instruments.
Because the Min/Max log is not time stamped in the PM130, reading these registers returns you
only values of the Min/Max log parameters which you can read directly via extended data
registers (see Table 5-15).

The Min/Max parameter value can be read in one or two registers depending on the value
type. For the value length and conversion scales, refer to Table 5-15. The time stamp is not
available in the PM130 and is read as zeros.

From 1 to 12 adjacent Min/Max log records can be read at a time via the Min/Max log windows. The
starting window #1 can be mapped to any Min/Max log parameter listed in Table 5-15 by writing the
parameter ID to the Min/Max log mapping register. This must be written before reading the Min/Max log
windows. Note that through Min/Max log windows, you can read only adjacent parameters within the same
Min/Max log data group. Reading parameters outside of the selected Min/Max log data group will return
zero.
