Maintenance: Self-Test Routine
NOTE: The monitor will add 50 mmHg to raw pressure data. In other words, the
value is always referenced to 0 mmHg regardless of any UA referencing
attempt.
NOTE: The recorder returns to its original on, off, or maternal-only mode state
from when the Test button was depressed.
NOTE: To disable the test, depress the Test button or open the recorder door.
NOTE: If the simulated fetal heart rate trends do not appear in the correct positions
on the strip chart recorder paper, ensure the monitor's paper scale (30-240
bpm or 50-210 bpm) setting matches the type of paper being used, i.e., 30
bpm/cm or 20 bpm/cm. (Refer
