Technical Characteristics
Equipment Overview: Technical Characteristics
General Description
The acquisition module performs high resolution ECG data acquisition
for use with host equipment (resting ECG analysis systems and exercise
systems). The acquisition m o du le has the following feature s:
■ ac leadfail bias,
■ l ead off dete ct ion,
■ 4000 Hz sampling rate,
■ patient isolation,
■ software updates via floppy diskette, and
■ Hi-Res analysis on 14-lead units
■ fu nc ti on key cont rol of host equi pme nt fu nc ti ons
The acquisition module provides patient electrical isolation for the host
equipment. The minute ECG s ignal s from th e pati ent’ s skin ar e rec eived
by the electrodes and sent to the acquisition module via leadwires. The
acquisition module then amplifies, digitizes, and performs some
processing on the signals.
This whole process is contro lle d by a microprocessor in the acquisition
module. The acquisition module then sends the serial, digitized, ECG
data to the host equipment in 16 bit “words”. The host equipment
communicates to the acquisition module using this same serial line.

Leakage Tests
The leakage tests are safety tests to ensure that the equipment poses no
electrical health hazards. Use the table below to determine which tests
apply to the unit under test and the maximum allowable leakage
currents. For international leakage limits, refer to the internal standards
agencies of that particular country.
If the unit under test fails the leakage tests, do not allow the customer to
use the equipment. Call Tech Support for assistance. (See the “How to
Reach Us” page in the front of the manual.)
GE Marquette Medical Systems recommends that you perform these
tests:
■ Before applying power fo r the first time
■ Every 6 months as part of routine maintenance
■ Whenever internal assemblies are serviced
You need a leakage tester to perform the leakage tests.
NOTE
The accuracy of the leakage tests depends on a
properly-wired wall outlet. Do not proceed until you
verify the integrity of the power source.
WARNING

Ground Continuity
This test verifies that there is continuity (less than 100 mΩ resistance)
between all the exposed metal surfaces on the host equipment, which
have the potential to become energized, and the ground prong on the
mains AC power cord. If the metal surfaces are anodized or painted,
scrape off a small ar e a in an inconspicuous area for the probe to make
direct contact with the metal.
Use a digital multimeter to check all the metal surface s of the host
equipment. Make ad justments for any res istance in the test leads. (See
the host equipment field service manual for detailed information.)
If the measurements are significantly out of range, check for breaks in
the power cord or in the internal connections within the unit.
