M1700A Pagewriter Xli Cardiograph With Preview Display - HP PageWriter XL M1705B Service Manual

Figure l-l. M1700A PageWriter XLi Cardiograph with Preview Display.
The PageWriter XL family of cardiographs can print ECGs in Auto
and Manual formats for different clinical tests or applications. Both
cardiographs print all traces with a continuous feed, high-resolution,
digital array printer. This produces electrocardiograms on standard
page lengths that require
no
cutting or mounting. Records are clearly
annotated with ECG data and patient information. The M1700A
also labels records with automatic ECG measurements and ECG
interpretation for both adult and pediatric patients.
The Ml700 ant1 M1701A cardiographs use flexible disks for storing
ECGs. Exact ECG copies can be made at the bedside or Iater. Each
ECG is automatically logged and can be automatically stored by the
cardiograph. A list of all stored ECGs can be printed, facilitating
administrative reporting and billing. Typically, 50-150 ECGS can
be stored per flexible disk, although the actual quantity depends on
usage.
From a service standpoint, the PageWriter XL cardiographs are
similar except for five major hardware differences:
H The h41700A preview display allows you to view the ECG prior to
recording.

The M1700A CPU assembly has extra nlenlory to accommodate
the measurement and interpretation software, but uses the same
ROM as the M1701A.

Each PageWriter has a unique CPU asscnibly.
