Introduction
Warning
Note
This chapter introduces you to the M1700A PageWriter XLi,
M1701A PageWriter XLs, and M1702A PageWriter XLe cardiographs
and lists their technical specifications.
These cardiographs are only to be serviced by qualified personnel.
Safe and effective use of medical instrumentation requires periodic
inspection and preventive maintenance. Perform the preventive
maintenance procedures in Chapter 4 of this manual at required
intervals to ensure satisfactory instrument performance.
The cardiographs use a thermal printhead to record waveforms and
label the ECG report. The paper supplied with the cardiographs is a
special thermal paper designed specifically to work with the thermal
printhead and the photo detector used to advance the paper.
The cardiograph's clisk drive (M1700A & M1701A only) is a critical
part. Disks of substandard quality can damage the clrive or destroy
patient clata.
Hewlett-Packarcl guarantees the performance of the cardiographs only
when used with paper and disks that meet or exceed Hewlett-Packard
specifications.
PageWriter XL
Cardiographs
The M1700A PageWriter XLi is Hewlett-Packard's full-featured,
interpretive cardiograph. The M1701A PageWriter XLs is the
standard, non-interpretive cardiograph. The M1702A PageWriter
XLe is the basic, non-interpretive cardiograph. Each cardiograph
uses a patient module, which is a remote "front end" that acquires
and digitizes clata. The M1700A and M1701A patient modules
feature a start button ant1 an LCD display that indicates signal
quality. The M1702A patient module does not feature a display
or start button. The cardiograph main unit has the user controls,
the disk drive (M1700A and M1701A only), the printer, and all the
processing circuitry. All models use the same enclosure, except when
the h41700A is equipped with preview display. The models fit onto
the M1705A cart clesignecl for these carcliographs. Figure l-1 shows
the M1700A with preview display mounted
on
the cart.
