CHECKING THE THERMAL PROBES IN THE i-STAT ANALYZERS
Verification for
Handheld Analyzers
Verify the thermal probe check for the i-STAT Portable Clinical Analyzer and
i-STAT1Analyzerasfollows:
• ExternalElectronicSimulatorusedroutinelyandresults transmitted
to a Central Data Station Version 4: On the CDS, click on System,
then on Simulator Results. Look under the Delta column. Check
thatthereis a valueequaltoor less than0.1(≤0.1)listed for each
analyzerinuseinthe last 30 days. A value of “--.--” indicatesthat
the conditions to complete the thermal probe check were not met.

Procedure for
Handheld Analyzers
Check the thermal probes on the i-STAT Portable Clinical Analyzer and i-STAT 1
Analyzerasfollows:
1. If the analyzer and simulator have been stored separately in areas
wheretheambienttemperaturediffersbymorethan3°C(5°F),allow
thesimulatorandanalyzertostandinthesameplace,outofdrafts,
for 30 minutes before inserting the simulator into the analyzer.
Handle the simulator as little as possible to maintain its thermal
uniformity and stability.
2. Insert the simulator into the analyzer.
3. When results are displayed, the difference between the thermal
probescanbeviewedontheanalyzer’sscreen:
•
PortableClinicalAnalyzer:whileholdingdowntheDISkey,press
the 1 key.
•
i-STAT 1 Analyzer: press the period key.
4. Interpretation of the thermal probe check value:
•
Acceptable:avalueequaltoorlessthan0.1(≤0.1)
•
Notacceptable:aFAILmessagewitha“t”QualityCheckCodeor
avaluegreaterthan0.1.Repeattheproceduretoconfirmresults.
Contact your Technical Support representative if the repeat thermal
checkvalueisgreaterthan0.1.
•
Repeattheprocedure:if“--.--”isdisplayed.Takecaretohandle
the simulator a little as possible. It may help to partially insert the
simulator into the analyzer and let it stand for 15 minutes before
insertingalltheway.
