readings provided by an NPB Model N-400 are
printed at selected intervals on the strip chart paper of the 120 Series Monitor.

top and bottom grids. A filled diamond marker, above the measured values, marks
the time of the reading and identifies the data source as an external device. The
following is an example annotation:
