• To print the trend memory, press the TREND button. Data
is printed at the rate of approximately 1 hour of data per
minute. If prior to printing the trend memory, the strip-
chart recorder was printing real-time data, the beginning
and end of the trend data are identified by zero-voltage
outputs.
• The trend output can be stopped at any time by again
pressing the TREND button. To restart it, push the
TREND button again—if less than 30 seconds have
elapsed, the output continues from the point at which it
was stopped; if more than 30 seconds have elapsed, the
output starts again at the beginning.
The following automatic markers appear on the trend graphs
printed by an analog strip-chart recorder:
Occurrence Marker
Beginning of trend output A 1-second, zero-voltage
output followed by two full-
scale deflections
End of trend output A 2-second, zero-voltage
output
Time when signal is acquired A full-scale to current-value
deflection
Time when pulse signal is
lost
A full-scale to current-value
deflection
Time when N-200 is turned
off
A full-scale to current-value
deflection
Event-limit or user-defined
event
A full-scale to zero-voltage
deflection
Note: The monitor can only store 60 events; if more than 60
occur, only the last 60 will be retained.
