Embla · Model Sandman Elite
High Quality: - Exceptional recording, scoring, and data management features - Records high-quality data to produce first-class studies and reports for your laboratory - Fully integrated "out of center" sleep testing with Embletta MPR - Microsoft Windows 7, 64-bit compatible. Tools You Need: - Select from a range of modules available for computer assisted scoring, data export, and database management - Bi-directional support of HL7 integration - Craft report tools with customized formulas, layout, and logo. Customizable Signal windows and workspaces allow users to view multiple signal windows at different time bases and allow for the simultaneous review of data from different points in time. This useful tool can be used during collection and allows review of look back data and real time data simultaneously. Digital Display and Running Digital Displays of alpha numeric data for any channel or event tag can be customized to view values of signals as they are collected. Patient Observations can be customized and allows for collection of observations during acquisition at timed intervals or on demand and is available for review when the study is opened in Analysis. RDI Summary tool provides information to the recording technologist about the effectiveness of changes in therapy during collection.
Key tips
- ·Run QC controls before trusting any repair - an analyzer that passes self-test can still report clinically wrong results.
- ·Rule out a reagent lot change before opening the instrument - it can look exactly like a hardware fault.
- ·Centrifuge rotors have a hard retirement age/cycle limit regardless of visible condition - don't eyeball it.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Noisy / high-impedance channels
HighSymptoms: Mains hum, drift or flat channels, persistently high electrode impedance, poor recording quality.
Root cause: Electrode / lead-wire wear, the electrode box (headbox) inputs, or poor skin prep / environment.
Headbox / amplifier fault
MediumSymptoms: A block of channels dead or saturated regardless of electrode, calibration / bio-cal fails.
Root cause: Headbox amplifier or its cable to the acquisition unit.
Amplifier-to-PC link / acquisition fault
MediumSymptoms: Recording drops, amplifier not detected, data gaps.
Root cause: USB / fibre / network link or a driver.
Photic stimulator / video / audio fault (diagnostic EEG/PSG)
LowSymptoms: Photic strobe not firing, no synchronised video, no audio.
Root cause: Photic lamp / trigger, the video camera, or the audio path.
PSG sensor fault (airflow / effort / SpO2 / limb)
LowSymptoms: A PSG channel (thermistor, pressure, RIP belt, SpO2, PLM) flat or noisy.
Root cause: Worn PSG sensor or its cable.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC controls run and reviewed
- ·Calibration verification per assay
- ·Routine cleaning and decontamination
- ·Scheduled reagent-path and pump-tubing maintenance
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: QC / calibration failure across a channel or the whole system
- Run fresh controls at all levels and note which analytes fail.
- Confirm reagents are in date, correctly loaded, mixed and not bubbled.
- Run the photometer / lamp-energy check and replace the lamp if energy is low.
- Clean the sample and reagent probes, the mixers and the wash / cuvette-wash stations.
- Recalibrate the affected assay / ISE module and re-run QC.
Symptom: Sample or reagent probe clog / crash / short aspiration
- Inspect the probe for a bend or blockage and clear it (wire / sonicate per the manual).
- Run the fluidics prime and the probe-wash cycle.
- Check for a clot or fibrin in the sample and the liquid-level sensing.
- Verify probe positioning / alignment.
- Replace the probe if aspiration is still short.
Symptom: ISE electrolyte results biased or noisy / ISE calibration fails
- Run the ISE calibration and check the slope / drift against spec.
- Replace an ISE electrode or the reference that is at end of life.
- Check the ISE pinch valves and tubing for wear or air.
- Confirm the ISE standard packs are in date.
- Re-run ISE QC before releasing electrolyte results.
Symptom: High cuvette blanks / position-dependent results
- Run the cuvette blank / photometric check.
- Clean or replace worn / scratched cuvettes or the reaction segment.
- Check the cuvette-wash station nozzles and drying.
- Confirm the water / DI supply quality.
- Recalibrate and re-run QC.
