CMMS documentation

Required Tools and Equipment

Protective gloves
Cloth
Alcohol
Water
Thermal recording paper, if replacement is needed
Scissors, if replacing paper
Commercial urine analyzer control solution
AUTION 10EA Sticks
Check strip set, if performing check measurement
Electrical safety analyzer, if required by facility policy

Important: Do not use alcohol, thinner, organic solvents, or ultrasonic cleaning on the test strip tray. The manual warns these methods may deform, discolor, or cloud parts and make them unserviceable.

Step-by-Step PM Procedure

1. Confirm Device Status

Action: Confirm the analyzer is at the standby screen before shutdown or maintenance.

Expected outcome: Analyzer is idle and not processing a specimen.

Why it matters: Maintenance during measurement can interrupt testing or affect results.

2. Power Off the Analyzer

Action: Turn the power switch OFF before cleaning.

Expected outcome: Analyzer is powered down before internal cleaning.

Why it matters: The feeder, carrying arm, and internal areas are cleaned with the analyzer off.

3. Use Biohazard Precautions

Action: Wear protective gloves before handling the test strip tray, carrying arm, suction ports, feeder parts, or waste box.

Expected outcome: Staff are protected from urine residue and used test strips.

Why it matters: The manual repeatedly warns that urine and used test strips may contain pathogenic microorganisms.

4. Inspect Used Test Strip Waste

Action: Pull out the waste box and check for used test strips. Empty if needed.

Expected outcome: Waste box is not full and used strips are discarded per local biohazard policy.

Manual note: The waste box gets full after approximately 100 measurements.

5. Clean the Carrying Arm

Action: Remove the carrying arm. Sterilize it using alcohol, wash it with water, and dry it with a cloth.

Expected outcome: Carrying arm is clean, dry, and free of sample residue.

Why it matters: Residue can interfere with smooth test strip movement.

6. Clean the Test Strip Tray and Suction Ports

Action: Remove the test strip tray and suction ports. Wash with water and dry with a cloth.

Expected outcome: Tray and suction ports are clean, dry, undamaged, and reinstalled correctly.

Important: Do not sterilize the test strip tray with alcohol. The manual warns this may cloud the test strip detection window and cause detection errors.

7. Clean the Test Strip Feed Tray and Feed Lever

Action: Remove the test strip feed tray and feed lever. Wash with water and dry with a cloth.

Expected outcome: Feed components are clean and dry.

Why it matters: Dirty or damaged feed parts may cause strip jams, transport errors, or inaccurate measurement.

8. Clean Internal Feed Areas

Action: Clean dirt or residue from the test strip guides, photometric table guides, incoming strip sensor window, test strip aligning levers, aligning arm, and white plate.

Expected outcome: Sensor and feed areas are clean and free of urine residue, debris, or scattered test strips.

9. Reassemble Feeder Components

Action: Reinstall the feed lever, test strip feed tray, suction ports, test strip tray, maintenance cover, and carrying arm.

Expected outcome: All components click or seat into their correct positions.

Important: The suction ports must be fully seated against the bottom of the tray. The manual warns that improper seating may cause strip transport problems, strip jams, or trouble.

10. Clean the Waste Box

Action: Sterilize the waste box using alcohol, wash it with water, dry it with a cloth, and reinstall it.

Expected outcome: Waste box is clean, dry, empty, and properly installed.

Important: Do not place tissue paper or similar material in the bottom of the waste box. The manual warns this may cause problems when disposing of waste.

11. Check Thermal Recording Paper

Action: Inspect the printer paper. If red lines appear on both sides, replace the roll.

Expected outcome: Printer has adequate paper for result printing.

Manual note: A new roll of thermal recording paper can be used for approximately 450 measurements.

If replacing paper:

Open printer cover.
Remove remaining paper or paper core.
Cut the end of the new roll straight.
Install the roll so paper feeds from the bottom.
Feed paper through the slot.
Press the FEED button after replacement.
Close the printer cover.

12. Power On and Verify Startup

Action: Turn the analyzer ON and allow startup to complete.

Expected outcome: Analyzer completes initialization and returns to the standby screen.

Manual note: Startup includes display icon check, product/version display, backup memory check, and approximately 20 seconds of mechanism initialization.

13. Review QC / Control Measurement Status

Action: Confirm the analyzer’s QC status according to laboratory policy. Perform control measurement if due.

Expected outcome: QC is current and acceptable before patient testing.

Manufacturer-listed QC timing: Controls should be used daily, whenever a new bottle of strips is opened, before reporting unusual or unexpected results, and when training new operators.

14. Perform Control Measurement if Required

Action: Use commercial control solution and AUTION 10EA Sticks. Dip the test strip pad area for approximately 2 seconds, avoiding the black mark, and place the strip on the test strip tray.

Expected outcome: Control result is within the expected range from the control solution package insert and laboratory QC policy.

15. Perform Check Measurement if Needed

Action: If sample results are odd or questionable, perform check measurement using one white and one gray check strip. Clean feeder and waste box before check measurement.

Expected outcome: Printed reflectance values are within the ranges listed on the check strip bottle reflectance label.

If results are outside range:

Repeat using the other two check strips in the bottle.
If the repeat passes, do not reuse the first check strips.
If repeat results are still outside range, remove the analyzer from service and contact the distributor.

Electrical Safety Testing if applicable

The provided operating manual does not list a specific preventive-maintenance electrical safety test requirement or leakage-current limit.

Document electrical safety testing if required by facility policy, after repair, after power supply replacement, or under the facility’s medical equipment safety program.

Ground resistance measured in ohms, expected ≤ 0.5 Ω or facility/NFPA 99 criteria if different:
