Q3000 controller with Q55 treadmill.
The Q 3000 controls the treadmill speed and
grade by means of the selected protocol and
displays
speed and grade information in the numeric
display.
ECG data is collected from electrode sites
on the body.
Computes heart rate, ST parameters, and other
information.
Hardcopy print of ECG and computed information.
Specifications:
Overall System
Frequency response: 0.05 to 100 Hz (+1,-3dB)

20 mm/mV. Filters: 25 Hz, 4-pole, low pass
artifact filter for the screen and a 25 Hz,
low pass digital filter for the chart recorder;
key selectable. Overall signal error: for a ±0.5
to ±5.0 mV signal, error is less than ±10%
or 50 µV, whichever is greater. Input
impedance: 10 megohms minimum. Common mode
rejection: 100 dB at 60 Hz. Power requirements:
90-132 VAC, 45/450 Hz, 500VA; 180-264 VAC,
45/450 Hz, 500VA; 250-375 VDC, 350 W. Dimensions:

x 158.2 x 77.5 cm) WxHxD. Weight: 300 lbs (136
kg)
Screen
Description
Displays 3 channels
of ECG waveforms plus alphanumeric information
for identification and labelling purposes,
calculated parameters, and messages to the
operator. Size: 9x7 inches (23x18cm) WxH. Sweep
speed: 25 mm/sec. Memory span: 8 seconds for
each channel. HOLD feature: split screen format
with oldest 4 seconds of ECG display capable
of being frozen. Write from memory: both HOLD
and continoues ECG may be written from the
CRT memory to the chart recorder with full
AHA diagnostic quality.
Chart Recorder
Description: records three 5 mm wide ECG channels
and a 45 mm wide half channel containing
alphanumeric data for labelling and calculated
parameters. Writing method: high-resolution,
thermal printhead. Speeds: 5, 25, and 50
mm/sec. Paper capacity: 200 feet (61 m) of
z-fold paper. Paper size: 8 ½" x
11" ( 216 x 280 mm). Papertype: thermal
paper, z-fold.
ECG Computations
Calculated parameters: heart rate, ST level,
and ST slope. Fiducial point for ST measurement:
J- junction.
Timers
Description: alphanumeric screen readouts of
stage number, stage time, exercise time,
and recovery time. Accuracy:±0.1% ±1
second.
ECG Simulator
Outputs are simulated ECG signals for the 14
electrode sites; heart sites; heart rate
is 30 to 240 bpm, user selectable through
the test and calibration mode.
Patient Cable
14-wire, low-noise, shielded cable for developing
the 12 standard leads and the XYZ Frank leads.
Color coded connectors.
Rear Panel Outputs
TTL compatible QRS synchronization pulse; mini-phone
jack. Three-channel, analog ECG output, mini-phone
jacks. Treadmill interface, 25-pin D connector.
