Press the Volume button to ensure that both valves are closed.
5
Perform an offset adjustment so that the simulator and monitor both display a
pressure of 0 mmHg or kPa by doing the following:
pressure of 0 mmHg or kPa by doing the following:
a. Press the Contrast button on the monitor’s front panel.
b. If needed, zero the simulator (see “To Zero the Simulator” on page 4-16).

Press the Start button on the simulator. The peak value (X4) shown on the
simulator should be between 270 mmHg and 330 mmHg (35.9 kPa and 43.9
kPa). The pressure should return to 0 automatically on the monitor and
simulator). Both conditions should be true for the monitor to pass this test.
