The following sections outline the appropriate testing, disassembly and re-
assembly procedures for the individual mechanical components of the Bard
CritiCore Monitor.
Bezel Enclosure
The bezel enclosure (Figure 6) protects. the underside of the display PCB
from impact and contamination by foreign matter. The bezel is directly
attached to the bezel top and is hinged to the front enclosure by the hinge
pins. The magnets inserted and affixed to the bezel enclosure are drawn to
the attraction plates which are attached to the front enclosure.
The force of
attraction is necessary to apply pressure to ihe top of the disposable
container. The force on the container cap ensures that the container is firmly
seated on the transducer cap.
This in turn allows for minimal transducer
signal loss when the container holds little or no fluid.
Visually inspect the bezel enclosure for damage.
if the bezel enclosure is
broken or cracked, it may allow fluid to enter into the display PCB and should
be replaced.
If one or both of the magnets are missing or damaged, they
must be replaced.
See the Attraction Plates and Magnets section (on page
40) for magnet replacement procedure.
1.
Place a disposable container into the Monitor.
2.
_Lift the display assembly up approximately 1/2 inch and allow it to drop
onto the container cap. The dispiay assembly should drop unhindered
and rest on the container cap.
3.
ff the bezel enclosure hinge pin insert is cracked, or if there is foreign
material inside the hinge pin/insert junction, the movement of the display
assembly may be hindered. To inspect for cracks inside the hinge pin
insert, remove the hinge pins as described in the Removing the Bezel
Enclosure procedure (below). If cracks are found, the bezel enclosure
must be replaced.
lf foreign matter is the cause, clean out the plastic
insert and hinge pin by using a non abrasive cloth dampened with 70%
isopropyl alcohol.
Equipment Required
*
No. 2 Phillips screwdriver
e | Needle nose pliers
Caution:
The Bard CritiCore Monitor main and display PCB's contain
static sensitive electronic devices.
Do not attempt to repair any
internal components without proper ESD (Electro-Static
Discharge) handling equipment.
Failure to properly ground both
your body and your work station could result in damage to the
Monitor.
