Accurex Lipid Profile Meter Error Codes & Troubleshooting Guide
Dr Pramod kumar
The Accurex Lipid Profile Meter / LPM-101 Blood Lipid Analysis System can display error messages when the meter detects a problem involving the optical sensor, test strip, battery, code chip, environmental temperature or measured lipid result.
Understanding these messages can help distinguish a simple correctable testing problem from a situation that requires a fresh strip, meter maintenance or professional technical support.
The LPM-101 manufacturer's troubleshooting table documents the following messages:
E-1, E-2, E-3, E-4, E-6, E-7, HI and Lo.
Importantly, the manual version reviewed for this guide does not list an E-5 troubleshooting code. If your specific meter revision displays E-5, refer to the manual supplied with that exact device or contact the authorised supplier rather than assuming the meaning.
Accurex LPM-101 Error Codes at a Glance
| Display | Likely Cause | What to Do |
|---|---|---|
| E-1 | Sensor area dirty, blocked or damaged at startup | Remove obstruction, clean sensor area carefully, restart meter; seek service if sensor window is damaged |
| E-2 | Test strip removed during measurement | Repeat with a fresh strip and keep it inserted until testing is complete |
| E-3 | Expired test strip | Replace the strips and corresponding code chip and check expiry information |
| E-4 | Battery power too low for testing | Charge the meter before attempting another test |
| E-6 | Code chip removed, missing or not recognised correctly | Insert the proper code chip, verify it matches the current strip pack and repeat testing |
| E-7 | Operating temperature below 10°C or above 35°C | Move the meter and test materials to a 10°C–35°C environment and allow them to equilibrate |
| HI | Result exceeds the applicable measurement range | Repeat with a fresh strip and obtain appropriate medical or laboratory assessment |
| Lo | Result is below the applicable measurement range | Repeat with a fresh strip and obtain appropriate medical or laboratory assessment |
Accurex E-1 Error: Sensor Area Dirty, Blocked or Damaged
E-1 indicates a problem with the meter's optical sensor area during startup.
Possible causes include:
- A used test strip left inside the meter
- Dust or contamination in the strip holder
- Material blocking the optical sensor
- A damaged transparent sensor window
How to Correct E-1
- Remove any strip or object from the meter.
- Inspect the test-strip holder.
- Clean the sensor area carefully.
- Restart the meter.
- Repeat only after confirming that the sensor area is clear.
If the transparent sensor window appears cracked, scratched or physically damaged, contact the appropriate supplier or service provider.
How to Clean the Accurex Sensor Area
The LPM-101 uses reflectance photometry, so keeping the optical pathway clean is important.
The manufacturer recommends using a soft cotton swab around the sensor area.
Do not:
- Scratch the transparent sensor window
- Insert sharp objects into the strip holder
- Pour liquid into the meter
- Use petrol, paint thinner or similar organic solvents
The test-strip holder can be wiped with a damp cloth or mild detergent and then dried with a clean, soft cloth.
Accurex E-2 Error: Test Strip Removed During Testing
E-2 means the test strip was removed while measurement was still in progress.
Once a specimen has been applied, leave the strip fully inserted until the meter displays the completed result.
How to Correct E-2
Discard the interrupted strip and repeat testing using a new compatible test strip.
During the repeated test:
- Insert the strip completely.
- Apply the correct specimen volume.
- Do not move the strip.
- Do not remove it while the progress indication is displayed.
E-2 Can Also Follow an Incorrect Sample Application
The manufacturer's strip instructions emphasise that the specimen application area must be correctly filled.
For the LPS-101 3-in-1 lipid panel, approximately 35 µL of specimen is required.
Some parameter-specific strips use approximately 10 µL.
If too little or too much specimen is applied, discard the used strip and repeat the procedure with a fresh strip.
Do not add more blood later to an inadequately filled strip.
Accurex E-3 Error: Expired Test Strip
E-3 indicates that the meter has identified an expired test-strip condition.
Check All Three Dates
Review:
- The printed strip expiry date
- The opened-canister date where applicable
- The meter's internal date setting
For canister-packed Accurex lipid strips, the manufacturer specifies an opened-canister period of approximately 3 months after first opening.
Use whichever applicable expiry limit occurs first.

Accurex E-4 Error: Battery Too Low
E-4 means the built-in battery does not have enough charge to perform the lipid test.
The meter must be charged before testing can continue.
Important: Accurex Cannot Test While Charging
The LPM-101 uses a rechargeable lithium battery, but the manufacturer states that the meter is non-operational for testing while charging.
If E-4 appears:
- Connect the meter to an appropriate USB charging source.
- Allow adequate charging.
- Disconnect the charging cable.
- Restart the meter.
- Perform the test after sufficient charge is available.
Accurex E-6 Error: Code Chip Problem
E-6 indicates that the code chip is missing, removed or not correctly recognised.
The code chip is an essential part of the Accurex testing system because it provides the calibration information corresponding to the current strip pack.
How to Correct E-6
- Locate the code chip supplied with the current strip box.
- Insert it properly into the code-chip slot.
- Check the code printed on the strip package.
- Compare it with the code shown by the meter.
- Confirm that both codes match.
- Repeat testing using a fresh strip where required.
Do not use an old code chip simply because it physically fits the meter.
Code Chip Must Match the Current Strip Lot
The compatible Accurex system supports different test-strip references:
- LPS-101
- TCS-101
- TGS-101
- HLS-101
Each new strip box should be used with the code chip supplied with that pack.

Accurex E-7 Error: Temperature Too High or Too Low
E-7 appears when the environment is outside the meter's permitted testing range.
The LPM-101 operating temperature is approximately:
10°C to 35°C
If the meter or test materials are too hot or too cold:
- Move them into a suitable indoor environment.
- Keep them away from direct sunlight or heaters.
- Allow the meter and testing materials to reach the operating temperature.
- Repeat the test with a fresh strip where necessary.
Do Not Confuse Strip Storage Temperature with Testing Temperature
| Condition | Specified Range |
|---|---|
| Test Strip Storage | 2°C–30°C; ≤90% RH |
| Meter / System During Testing | 10°C–35°C; ≤80% RH |
| Meter Storage / Transport | 0°C–55°C; ≤90% RH |
A meter may therefore be safely stored under conditions in which a lipid test should not yet be performed.
What Does HI Mean on the Accurex Lipid Meter?
HI indicates that the measured result is above the measurement limit for the applicable lipid parameter.
The LPM-101 manual specifies approximate analytical ranges of:
| Parameter | Measurement Range |
|---|---|
| Total Cholesterol | 100–500 mg/dL |
| HDL Cholesterol | 15–100 mg/dL |
| Triglycerides | 45–650 mg/dL |
Because the applicable limit depends on the parameter being measured, HI should not be interpreted as one single numeric value for every lipid test.
Repeat the test using a new strip and obtain appropriate professional or laboratory assessment if the result remains outside range.
What Does Lo Mean on the Accurex Lipid Meter?
Lo indicates a result below the lower measurement limit for the applicable lipid parameter.
Do not automatically assume that Lo represents the patient's exact lipid concentration.
Instead:
- Review the test procedure.
- Check the strip and code chip.
- Repeat with a new strip.
- Obtain appropriate laboratory confirmation when clinically relevant.
Why Accurex Results May Be Unexpected or Inconsistent
Not every testing problem generates an error code.
If results vary unexpectedly, check the complete testing workflow.
Common factors include:
- Expired strips
- Incorrect strip storage
- Wrong code chip
- Wrong specimen type selected
- Insufficient sample volume
- Too much sample
- Incorrect capillary sampling technique
- Contaminated strip
- Damaged strip
- Dirty optical sensor
- Testing outside 10°C–35°C
For Capillary Testing, Use the Correct Blood Drop
The manufacturer instructs users performing capillary testing to:
Wipe away the first blood drop and use the second or subsequent appropriate drop.
For the LPS-101 lipid panel, collect approximately 35 µL using the appropriate capillary transfer tube or pipette.
For the full step-by-step procedure:

What If Too Little Blood Was Applied?
If the specimen application area is not correctly filled:
Do not add additional blood to the same strip.
Discard the strip and repeat the test using a fresh strip and the correct specimen volume.
What If Too Much Blood Was Applied?
The manufacturer also warns that excess specimen can result in an improper test-strip fill.
If too much blood or specimen covers the application area, repeat the test with a new strip.
Accurex Meter Does Not Turn On
If the meter does not power on:
- Check whether the battery is discharged.
- Charge the meter using an appropriate USB power source.
- Inspect the charging connection.
- Disconnect the charger before attempting a lipid test.
- Restart the meter.
If the meter remains unresponsive after adequate charging, contact the appropriate service provider.
Accurex Meter Does Not Recognise the Test Strip
Check:
- That the strip belongs to the LPM-101 platform
- The strip orientation
- Whether it is inserted completely
- Strip expiry
- Physical strip damage
- The test-strip holder for contamination
Do not force a strip into the meter.
Accurex Code Does Not Match the Strip Pack
If the meter displays a code different from the strip pack:
Do not perform the test.
Remove the incorrect code chip and install the one supplied with the current strip box.
The code printed on:
- The strip package
- The code chip
- The meter display
should correspond before testing.
What If the Accurex Meter Was Dropped or Got Wet?
The manufacturer recommends performing an Optical Verify Strip test if the meter has been dropped or exposed to moisture.
This checks the optical reading system before relying on further testing.
Accurex Optical Verify Strip: OH vs FL
The LPM-101 optical verification system displays one of two results:
| Display | Meaning | Action |
|---|---|---|
| OH | Optical verification passed / meter functioning normally | Continue according to normal procedure |
| FL | Optical verification failed | Inspect verify strip for contamination or damage and repeat with a suitable verify strip |
The optical check should be performed under normal indoor laboratory lighting rather than direct sunlight or extreme lighting.
What If the Optical Check Shows FL?
Inspect the Optical Verify Strip.
If it is:
- Dirty
- Discoloured
- Contaminated
- Damaged
use an appropriate replacement verify strip and repeat the optical test.
For professional testing, do not rely on patient results from a meter with an unresolved optical-check failure.
When Should Accurex Quality Control Be Performed?
The manufacturer's manual recommends checking known controls in situations including:
- When a new package of test strips is opened
- When a new operator begins using the meter
- When test results appear inaccurate
- After meter maintenance or service
Individual laboratories should also follow their own quality-control policies and applicable accreditation or regulatory requirements.
What If the Control Result Is Outside the Expected Range?
Check:
- Test-strip expiry
- Whether the strip came from a properly stored pack
- Control-solution expiry
- Code-chip matching
- Operating temperature
- Testing technique
Repeat the control test carefully with appropriate fresh materials.
If quality-control results remain unacceptable, resolve the issue before relying on patient testing.
Cleaning and Maintenance Can Prevent Errors
The manufacturer recommends cleaning the LPM-101 after each day of testing.
Pay particular attention to:
- Test-strip holder
- Optical sensor area
- Exterior meter surface
A dry, soft cloth can be used for the LCD and optical area. Avoid allowing moisture, residue or control solution to enter the test-strip holder, code-chip slot or USB port.
