In fact, the recorder status and functions are set-up automatically and visualized via the display.
The dedicated keys

(DECOMPRESSION, which releases the pneumatic system and causes the
piston to speed back to its starting point, when depressurization is neces-
sary, see paragraph 2.4-Tail Cuffs).
BLUE
(START/REVERSE, see paragraph 7.3-Starting the Pressure Measure-
ment)
and the four functional keys

are the only operational commands.
The display and the functional keys combine to program the trial parameters selected by the op-

subheadings.
The upper rectangular window brings the linkage in sight and reassures the operator that the
pressure generator is doing its job.

Chart Recorder
This high-resolution, 50mm, real-time thermal printer of GSI LUMONICS, located on the
left side of the upper panel, has been selected as it offers a number of new features, in-
cluding warning messages to notify the user of undesirable conditions, thus preventing
errors.
See Figure 11 “Paper Roll”, self-explanatory on what concerns the replacement of the
chart roll.
The XE-50 communicates through a serial interface at 115,000 bits per second: when in
recorder mode it prints a simultaneous real-time waveform along with background grid,
