Setup Procedures: Service Mode Screens
Corolan Address Checking
This field enables/disables Corolan address checking. Use the Trim Knob control to
alternate between ON and OFF. (The factory default setting is OFF.) If the monitor
is not a device on a Corolan daisy-chain network, configure this field to OFF. If the
monitor is a device on a Corolan daisy-chain network, configure this field to ON.
When this option is set to ON, the monitor periodically performs an address and
LED test on the Corolan wallplate the monitor is attached to; if the monitor detects
an error it stores this information in the error log and the monitor automatically goes
offline from the Corolan network.
Heartbeat Coincidence
The heartbeat coincidence feature alerts you when there is the possibility that you
may be monitoring a duplicate signal. Heartbeat coincidence is indicated when any
two heartbeats have a consistent phase relationship for equal to or greater than 60%
of the detected beats for about 60 seconds; the cessation of coincidence is indicated
when the phase relationship is inconsistent for greater than 40% of the detected
beats for about seven seconds.
When heartbeat coincidence detection is enabled , the acronym
HBC
appears to the
right of the FHR2 mode title.
Smart BP
Models 128 and 129 have a Smart BP feature which prevents an automatic blood
pressure determination from occurring during a uterine contraction. This feature:
‹ reduces the chances for erroneous vital signs readings; and
‹
reduces patient discomfort during labor.
VS Print Interval
The monitor provides an option for the printing of blood pressure and MSpO2
values on the strip chart paper:
„ Real-Time: Values are printed according to the actual clock time (9:33, 9:48,
10:03, etc.).
„
Chart-Style: Values are printed on standard clock quarter (9:00. 9:15, 9:30:,
9:45, etc), half (9:00, 9:30, 10:00, 10:30, etc), and whole hour marks (9:00,
10:00, 11:00, 12:00, etc).
Recorder Font Size
The monitor offers a choice of font sizes to print annotations.
‹ Small: increases print speed.
‹
Medium: a compromise between the large and small sizes.
‹ Large: fosters readability.
