Touch Screen Display and Calibration Test (TD)
The touch screen can be calibrated at any time. Calibration is recommended if it requires many
attempts to select an item on the screen, or if selecting items on a specific area of the screen is
difficult.
The touch screen may also require calibration if the cardiograph is used in different settings
(seated instead of standing) or by users of significantly different height. The touch screen may
need to be recalibrated to work optimally in the new setting or with the new user. The Touch
Screen Calibration procedures and tests include:

PIM Test (PIM)
This test is used to confirm that the Patient Interface Module (PIM) is communicating with the
cardiograph. This test can be performed when the cardiograph displays PIM error messages, or
when the cardiograph is unable to acquire data from the PIM. Be sure that the PIM patient data
cable is securely attached to the PIM connector on the rear of the cardiograph before
performing the test.
If this test fails, it may indicate a problem with the PIM or with the PIM patient data cable.
To perform the PIM Test

Touch the Patient Interface Module (PIM) Test button.
