1) It is recommended to place the pressure sensor and its tee valve at the level of the axillary line, which is used for ventilation and sensor zeroing.
2) Approve the maintenance cap on the three-way valve to be perforated, connect the sensor to the monitor, and zero the sensor under atmospheric conditions according to the instructions of the monitor.
3) After the pressure sensor monitor is zeroed, close the three-way valve and the air communication port, and cover the non-hole maintenance cap.
4) The dynamic response of the square wave detection system. The dynamic response test should be performed after a series of procedures such as flushing the line, draining the air bubbles, and connecting to the patient, zeroing, and calibration.
Note: The system requires an equilibrium process of approximately one minute, then implement a small drop to see if the flushometer is outstanding and visually investigate for leaks. Check regularly 30 minutes after installation to ensure that the pressure of the infusion bag is normal, the flow rate is normal and there is no leakage. Any small leak may result in an incorrect reading of the monitor.
5) After the system is calibrated normally, dynamic monitoring will be carried out according to the requirements.

The key factor influencing sensor performance – the company
Because the metal material is used as the elastomer of the load cell load cell, when the fine particles between the external force and the micro-strain disappear, the micro-strain disappears, but whether it can be fully recovered to the original non-stress state will be changed according to the metal data of the elastomer.

Attention to the problem of testing six-wire load cells – we are blessed with it
Because the appearance of the six-wire sensor and the six-wire four-wire sensor can not be distinguished, before the measurement and verification personnel test the sensor, if they find that the sensor input and output cable has six wires, it should be clear whether the sensor is a six-wire sensor, and the six-wire load cell test can not use a fine digital voltmeter...

How to distinguish between good and bad angle sensors
The use of angle sensors in practical manipulation is relatively common, and may be useful for the needs of different occupations and different fields. No matter how good the instrument is, there is a quality of the instrument itself, and in order to reduce the presentation of errors in the measurement process, users need to choose a good quality ...
