31 - Care and Maintenance
Maintenance plan
Attention
Damage to device
•
Do not open the casing. Once the device is opened, all warranties will lapse.
Weekly Maintenance
Analysis review:
1. Review the print-out of your measurement analysis for:
•
Correctly entered times and intervals in accordance with the log.
•
Times of day/night transitions.
•
Correct standard values (nocturnal decrease).
2. Check the device, cuff and the cuff tubing for superficial soiling and clean it as specified in the Cleaning
section.
3. Check the cuff and the cuff tubing for superficial damage. In the event of damages return it to your Welch
Allyn specialist for inspection.
Checking battery voltage:
Always use fully charged or new batteries.
The battery voltage appears on the display of the ABPM 7100 for approximately 3 seconds after the device is
switched on. The battery voltage must be at least 2.6 volt to ensure a 24-hour measurement.
Maintenance every 2 years
As proof of continuous compliance to "Basic Requirements" pursuant to Directive 93/42/EEC, the ABPM 7100 must
be subjected to calibration checks every two years. In certain countries, this requirement may be regulated by national
laws or regulations.
Welch Allyn offers to provide calibration checks and the servicing comprising of the following:
•
Calibration check
•
Software updates (if required)
•
Functional check: Electronics, pump and pneumatic circuit
Except the calibration check, no further maintenance work for electronic compatibility are necessary.
Troubleshooting
Attention
Damage to device
•
Do not open the casing. Once the device is opened, all warranties will lapse.
Note
In the event of an incorrect measurement, the device will begin a new measurement after
3 minutes except in the case of the activation measurement.
Basic error sources
The following may cause error measurements or unintended events:
•
Switching off the device (e.g. at night)
•
The patient's arm movement during measurement
•
Incorrect cuff size
•
Cuff displacement while wearing it
•
Omitted successful initial measurement by the doctor
•
Wrong log set by the user
•
Empty, incorrectly charged or outdated batteries
•
Kinked or knotted cuff tubing
•
Severe arrhythmia
•
Not taking medication
•
External distorting factors such as physical activity or, for example, driving or using public transport during a
measurement may lead to motion-related artefacts or incorrect measurements.
Transmission error
The ABPM 7100 reviews the transmitted data to prevent errors. If an error occurs, "E004" will be shown on the
display.
Checklist
Please review the following checklist for any errors occurring during the operation of the ABPM 7100. Many errors
have simple causes:
•
Check to see that all cables are connected correctly.
•
Check to see whether the ABPM 7100 and the computer are switched on.
•
Check to see whether the batteries have sufficiently voltage.
Note
Some errors are combined with a continuous alarm for safety reasons. The continuous
alarm can be cancelled by pressing any button. If there is residual pressure inside the cuff,
open the cuff immediately.
