CHECK PROBE
This message is displayed to alert the operator when the probe needs to be
checked. For instance:
1. If the probe is operating outside of the normal operating range of
30.0°C
– 43.5°C (86°F to 110.3°F) during any automatic mode, this
message will be displayed.
2. If the probe is not connected to the 1/4 inch receptacle prior to
pressing any of the automatic modes button.
3. If the probe is dislodged from the patient.
4. If the PATIENT temperature falls below 30°C (86°F).
5. If the PATIENT temperature is greater than 43.5ºC (110.3ºF).
6. If the probe is defective or open.
7. If other than a 400 Series probe was connected to the 1/4 inch
receptacle.
As this message is displayed, the trouble alarm sounds and the unit shuts
down. The operator can silence the alarm by pressing the SILENCE
ALARM button. After silencing the alarm and checking the probe, the
operator must press the TEMP SET button to proceed; otherwise STATUS
will continue to display CHECK PROBE. The operator has 5 minutes to fix
the probe. If after that time the condition has not been cleared, the system
will trouble alarm again, even though the SILENCE ALARM button has
been previously pressed.
In
MONITOR ONLY MODE
, CHECK PROBE is displayed if:
1. The temperature goes out of the range 10.0°C
– 50.0°C (50°F –
122.0°F).
The trouble alarm sounds and cannot be silenced. The patient display is
blank. If the temperature comes back into range, the unit should resume
operation in
MONITOR ONLY MODE
.
In
MANUAL CONTROL MODE
, a probe out of range should result in the
PATIENT display going blank, but the unit continuing operation with no
error message. If the temperature comes back into range, the PATIENT
display should come back on.
BAD PROBE
While in any of the five automatic modes, if the patient probe indicates only
a direct short in the probe circuit this message occurs. As this message is
displayed, the trouble alarm sounds and the unit shuts down. This alarm
can be silenced using the SILENCE ALARM button. The operator then has
5 minutes to fix the probe. If after that time the condition has not been fixed,
the system will trouble alarm again, even though the SILENCE ALARM
button has been previously pressed. During this condition, the seven-
segment displays will both be blank.
While operating in
MANUAL CONTROL mode
, if a bad patient probe
develops, the heating/cooling system remains on, but the seven-segment
PATIENT display blanks.
While operating in the
MONITOR ONLY mode
, if a bad patient probe
develops,
the BAD PROBE message displays, the audible alarm sounds
and the “PATIENT” temperature display blanks. The audible alarm can be
silenced using the SILENCE ALARM button. The operator than has 5
minutes to fix the probe. If after that time the condition has not been fixed,
the system will trouble alarm again, even though the SILENCE ALARM
button has been previously pressed. Connecting a working probe in range
should clear the error message and return the unit to normal operation in
MONITOR ONLY mode
.
