CardioLab Amplifier Testing

2002938-002E
NOTE
When testing the amplifier, always make sure the RL ECG lead wire
is connected to the ground of the simulator or function generator. All
signals in the amplifier use this lead as a reference.
Make sure the patient catalog is set to System.
Click on the CardioLab tab in the Navigator window and create a
patient.
Use the appropriate study types for the type of amplifier the lab will
be using.
Create a new patient using the Amp Test study type for the correct
amplifier.
With the Real-Time display on page 1, connect the ECG cable from
the amp to your simulator. Verify signals.
Switch to page 2 of the Real-Time display and connect the pressure
output from your simulator to the pressure 1 input of the amp. Run
zero pressure data and zero the signal on the window by highlighting
it and pressing the zero key on the keyboard.
Run pressure data on the channel and verify the pressure signal.
Repeat the same procedure for all pressure waveforms.
Change the Real-Time display to page 3 and connect your simulator
to pins 1 and 2 of catheter block A.
Run signal data into pins 1 and 2, verify that all of the signals on the
page look identical.
Run through this same procedure for each of the successive pages.
Each page represents a different block.
Go to the Study Configuration menu and select Switch.
Choose the CIM/STIM study type for the appropriate amplifier.
Set the display to page 1 and connect the simulator to pins 1 and 2 of
catheter input module block A.
Run simulated data using pins 1 and 2. Then move the simulator
down the block. (i.e. pins 2 and 3, 4 and 5, etc.). Make sure the
signals look the same as you run down the block.
Repeat this procedure for each input module. Each page of signals is
set up to test one whole block.
To perform the stim test, go to the Real-Time channel configuration
and under the amplifier select STIM.
Go to the Display and Hardware Settings tab and turn auto-detect on
for all four stim channels.
