What This Guide Helps With
Troubleshooting when test strips are not detected, improperly inserted, or causing repeated read errors due to external factors.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the device from patient use if testing is delayed or unreliable.
- Use an alternate meter if needed.
Expected: Patient testing continues safely on another device
Why it matters: Delayed or inaccurate glucose readings can impact clinical decisions
Verify Correct Strip Type
- Confirm the strips being used are compatible with the Precision Xceed Pro (glucose vs ketone strips).
- Check strip vial labeling
- Ensure strips match device capability
Expected: Correct strip type is used
Why it matters: Incorrect strips will not be recognized by the meter
Inspect Strip Orientation and Insertion Technique
- Ensure the strip is inserted fully and in the correct direction.
- Insert strip firmly until it stops
- Confirm contact end is inserted first
Expected: Device detects strip and initiates test mode
Why it matters: Partial or reversed insertion prevents proper contact
Check Strip Condition and Expiration
- Inspect strips for damage, contamination, or expiration.
- Check expiration date on vial
- Inspect for bent, dirty, or exposed strips
Expected: New, clean, in-date strips function normally
Why it matters: Damaged or expired strips may not be recognized
Inspect the Strip Port for Contamination
- Look for debris, dried blood, or residue inside the strip port.
- Visually inspect port using a light
- Gently clean using approved method (dry, lint-free applicator or manufacturer guidance)
Expected: Clean port allows proper electrical contact
Why it matters: Contamination blocks communication between strip and meter
Power Cycle the Device
- Restart the meter to clear any temporary recognition errors.
- Turn device off and back on
- Reinsert strip after reboot
Expected: Device resets and recognizes strip
Why it matters: Clears minor software or detection faults
Test with a New Strip from a Different Lot (If Available)
- Rule out defective strip batch.
- Use a strip from a new vial or different lot
Expected: Device recognizes strip normally
Why it matters: Confirms whether issue is strip-related vs device-related
Observe for Repeated Failures or Intermittent Detection
- Determine if the issue is consistent across multiple attempts.
Expected:
- Consistent failure suggests device issue
- Intermittent detection may indicate worn contacts
Why it matters: Helps differentiate accessory vs device failure
If the Problem Persists
If all external causes have been ruled out and strips are still not recognized, the issue is likely internal (e.g., strip port contact failure or internal circuitry issue).
Remove the device from service, label it Out of Service, and send it for repair or bench evaluation.
Knowing when to stop is proper troubleshooting.
Clinical Use Tip
Never troubleshoot strip recognition issues while relying on the device for active patient testing. Always transition to a functioning meter first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Meter not recognizing test strips during patient glucose testing."
Cause
What was observed during troubleshooting.
Example:
"Contamination found in strip port preventing proper strip contact."
Resolution
What action was taken.
Example:
"Cleaned strip port and verified proper operation with new test strip."
Helpful Details to Include (If Known)
- Strip type verified (glucose vs ketone)
- Strip expiration date checked
- Multiple strip lots tested
- Strip port condition (clean/contaminated)
- Device response (no detection vs intermittent)
- Final device status (returned to service or sent for repair)
Final Thought
Effective troubleshooting starts with simple, external checks like strip type, condition, and port cleanliness. This approach protects patient safety, avoids unnecessary repairs, and ensures accurate documentation when escalation is required.
That is successful troubleshooting.
