Warnings & Cautions
Warnings
WARNING: There can be high voltage near the fuse, AC inlet and
transformer. Always unplug the electrocardiograph before taking it
apart.
Cautions
CAUTION: Always turn the electrocardiograph off and disconnect
the power cord before cleaning. Do not pour liquids (such as alcohol or
other cleaners) on the unit. This will cause severe electrical damage!

1 General Information
About the Atria Electrocardiographs
The Atria ECG is a multichannel non-interpretive/interpretive
electrocardiograph. You operate the electrocardiograph by pressing
various keys on the keypad. A thermal printer makes hard copy
printouts of text and waveforms for permanent records.
The servicing of the Atria electrocardiograph is similar regardless of
which model you have. Some of the information in this Service Manual
applies only to options which you may or may not have installed in
your electrocardiograph. Unless otherwise specified, the information in
this Service Manual applies to the Atria electrocardiographs.
Basic System Description
A simple diagram of the system is shown in Figure . When AC power
is not connected, an internal 14.4 V NiMH battery provides power for
all functions. This battery is recharged whenever the AC line is
connected.
The ECG data is acquired by hybrid circuits and sophisticated software
on the Logic board. Under microprocessor control, the
electrocardiograph samples, buffers and amplifies the analog ECG
signals before converting them to digital levels for further processing.
Input/output control circuitry handles communication with the front
end ECG signals, LCD (liquid crystal display), membrane switches,
thermal printer and external devices (if equipped).

2 Service & Maintenance
What You Will Need
You will need only standard electronics tools to perform any testing or repairs.
Test equipment must be in good condition and calibrated regularly. You will
need:
Before You Begin
A few words of caution are in order. Before you perform any service on the
electrocardiograph, be aware of:
High voltage
. There can be high voltage near the fuse, power inlet, and
transformer. Always unplug the electrocardiograph and remove the battery
pack before taking it apart.
Static electricity
. The CMOS (complimentary metal-oxide semiconductor)
chips on the electrocardiograph’s circuit board are extremely sensitive to static
electricity. The printhead and display are also sensitive to static. To minimize
the risk of damage, use a grounding strap and work on an antistatic surface.
Recording paper
. Do not use wax-coated or blush-coated paper in the
electrocardiograph. It will damage the printhead. Use only approved thermal
paper.
Preventive Maintenance
The purpose of preventive maintenance is to reduce or eliminate future
problems. Keeping the electrocardiograph in good operating condition ensures
that it will perform safely and provide accurate recordings.
At least once a year, you should:
✔
Visually inspect the electrocardiograph
✔ Clean the electrocardiograph
✔ Check the power cord
✔
Check the patient cable
✔ Check the leakage currents
If a repair is required, only qualified technicians should do the work.
✔
Digital Multimeter
✔
Leakage Current Meter/Safety Analyzer
✔
Electronic Heart Simulator

Chapter 2 Service & Maintenance
2-2 Atria Service Manual
Visual Inspection
Check for anything out of the ordinary. Are there any cracks or missing parts?
Are the cords and connectors damaged or weak? Does the electrocardiograph
seem to operate properly? If everything looks fine, but you still suspect a
problem, check inside the electrocardiograph for loose connections, burn
damage or contamination from liquids.
Cleaning
CAUTION: Always turn the electrocardiograph off and
disconnect the power cord before cleaning. Do not pour liquids
(such as alcohol or other cleaners) on the unit. This will cause
severe electrical damage!
The need for cleaning depends on the environment and how often the
electrocardiograph is used. Use a damp cloth to clean the housing. Avoid
abrasive cleaners or polishes. Wipe dry with a soft, clean cloth. Don’t forget to
wipe the paper compartment.
Power Cable and Brick Cable
Check the power cord and AC inlet for any visible signs of deterioration, loose
connections or burn damage.
Patient Cable
Check the patient cable and input connector for any visible signs of damage or
loose connections. Disconnect the patient cable from the unit and inspect it for
short circuits, broken wires or poor contacts by measuring the resistance (10k
± 10%) for individual electrode leads.

Printhead
Keep the thermal array printhead free of dirt and other foreign materials.
WARNING: The printhead is very sensitive to static
electricity. Use an antistatic work surface.
Light printing (particularly at the baseline) may be an indication that the
printhead is dirty. Use a small amount of ethanol or isopropyl alcohol and a
lint-free swab to remove residue. Avoid abrasives or cleaners which may
damage the printhead.

Factory Defaults
This function allows you to set all of the user programmable defaults back to
their original factory settings. The Atria automatically copies all backup files to
the active directories and powers down and back up again to ensure that the
new defaults are effective.
NOTE: All configuration values are reset to the default
values. Additionally, all passwords are cleared and must be
reset.
Printhead Resistance
Because individual printheads vary in resistance, you must enter the printhead
resistance whenever the logic PCB or paper drive assembly has been replaced.
To enter the printhead resistance:
1. Compare the displayed value to the value written on the
printhead.
2. If the displayed value is incorrect, press backspace three times
to erase the current setting and type in the value printed on the
printhead.
CAUTION: Setting the printhead resistance to any value
other than the value written on the printhead will shorten the
life expectancy of the printhead and may void your warranty.
Printer Test Sequence
This function prints out three test pages which you can use to verify that the
printer is printing correctly across the full width of the printhead.
Printer Test Alternate Sequence
This function prints out a series of test pages which you can use to verify that
the printer is printing correctly across the full width of the printhead. Printer
Test Alternate prints continuously until you press .

Measuring Chassis Leakage Current
Use a high quality meter or safety analyzer capable of testing to AAMI
specifications. An inappropriate meter can produce erroneous leakage
readings. Do the leakage tests at a nonconductive work station.
Be careful! The meter must be suitably insulated and capable of withstanding
the power line voltage.
To check the chassis leakage current:
1. Connect a leakage meter between the chassis ground jack (at
rear panel) and power line ground. Make sure the leakage
current is less than 300µA.
2. Open ground line and verify that leakage current is less than
300µA.
3. Reverse line polarity and verify that leakage current is less than
300µA with ground closed.
4. With reversed polarity, open ground line and ensure leakage is
less than 300µA.

Measuring Patient Leakage Current
Use a high quality meter or safety analyzer capable of testing to AAMI
specifications. An inappropriate meter can produce erroneous leakage
readings. Do the tests at a nonconductive work station.
Be careful! The meter must be suitably insulated and capable of withstanding
the power line voltage.
To check the patient leakage current:
1. Connect the patient cable to the Atria.
2. Connect all patient cable leads together (it’s easiest to use a
safety analyzer).
3. Connect a leakage meter between patient cable leads and power
line ground. Make sure the leakage is less than 10µA.
4. Open ground line and verify that leakage current is less than
10µA.
5. Reverse line polarity and verify that leakage current is less than
10µA with ground closed.
6. With reversed polarity, open ground line and ensure leakage is
less than 10µA.
