Time Base Operation
You can use the X-Y Recorder in a time-based mode, if de-
sired. The Y-Axis signal is plotted against a recorder-gener-
ated time base which can be correlated with crosshead
speed. The time scale can be switch-selected for a range of
0.1 seconds per centimeter to 50 seconds per centimeter or
0.25 seconds per inch up to 125 seconds per inch.
Since the Model 5500 uses chart speeds in units of
inches/minute or centimeters/minute, and the Recorder
Time Scale is in units of seconds/inch or seconds/centime-
ter, Table 6-5 gives speed conversions between the two.
