Read all instructions included with the appropriate CODMAN
MicroSensor ICP Transducer Kit regarding proper operation
prior to use.
Operation
1. Connect the four pin end of the ICP EXPRESS Cable to the
white connector on the CODMAN MicroSensor ICP Transducer.
2. Line up to white indicator marks on the ICP EXPRESS Cable
plug and the ICP EXPRESS Monitor front panel receptacle. Guide
the plug into the receptacle until a visible flick of the plug and
an accompanying audible "click" occur. This confirms that the
connectors are fully mated and locked.
3. Zero the attached MicroSensor as prompted by the ICP
EXPRESS Monitor. When zeroing is complete, the zero reference of
the MicroSensor will be stored automatically in the ICP EXPRESS
Cable. Refer to the ICP EXPRESS Monitor Instruction Manual for
full details.
NOTE: A transducer ZERO REFERENCE value of "-99", as
displayed by the ICP EXPRESS Monitor during a manual zeroing
or zero reference verification procedure, is an indication of an
ICP EXPRESS Monitor EEPROM read failure. This may be a result
of a simple random timing error by the ICP EXPRESS Monitor
and may be corrected by selecting the "ADJUST REFERENCE"
menu item and manually adjusting the displayed zero reference
to the correct value. However, the error may also be an indication
of a failure in the ICP EXPRESS Cable EEPROM circuit due to
deterioration associated with age or mechanical abuse.
CAUTION: Discontinue use of any ICP EXPRESS Cable that
continues to yield a "-99" transducer zero reference value
(as displayed on the ICP EXPRESS Monitor display) during
manual zeroing or zero reference verification procedures.
4. To disconnect the ICP EXPRESS Cable from the ICP EXPRESS
Monitor, grasp the plug near the white indicator mark and twist one
quarter turn clockwise while withdrawing.
Preventive Maintenance
CAUTION: Verify ICP EXPRESS Cable integrity prior to use.
Do not use an ICP EXPRESS Cable that fails to meet the
pin-to-pin resistance or electrical leakage specifications.
The ICP EXPRESS Cable's integrity should be routinely evaluated
by qualified technical personnel. The ICP EXPRESS Cable should
be inspected for pin-to-pin resistance and electrical leakage.
Pin-to-pin resistance may be measured using an ohmmeter.
Resistances between pins 1–1, 2–2, 3–3, and 4–4, must be
one ohm or less (refer to Figure 1).
Electrical leakage may be evaluated using an ohmmeter to
measure the open circuit resistance between pins 1, 2, 3, 4
(inclusive), and all other pins accessible on the ICP EXPRESS
connector end. The open circuit resistances must be 300 M
or greater.
