Questions and answers
Добрый день. Тонометр СТ800 (номер 2865917) - показания неверны, завышены. пробовали протирать стекло и сопло, результатов нет. В чем может быть причина?
Inaccurate and elevated readings on the Topcon CT-800 tonometer could be caused by several factors, including:
1. Improper Patient Positioning – If the patient is not properly aligned with the instrument, measurements may be incorrect.
2. Incorrect Use of the Z Alignment Mark – Misalignment during operation can lead to errors in intraocular pressure readings.
3. Environmental Conditions – The device should be used in a controlled environment (temperature: 10-40°C, humidity: 30-90%, pressure: 700-1,060 hPa). Extreme conditions may affect accuracy.
4. Direct Sunlight Exposure – Placing the instrument in direct sunlight can interfere with its operation.
5. Measurement Errors – If the reliability of the measurement is low, readings may be inaccurate. The device may indicate errors such as "ERROR" or "OVER" when the measurement is not done correctly or exceeds the range.
6. Improper Maintenance – Dust, dirt, or a misaligned measuring nozzle can affect the device’s performance, leading to incorrect readings.
Ensuring proper alignment, environmental conditions, and regular maintenance can help achieve accurate intraocular pressure measurements.
