How to resolve inaccurate test accuracy. Nowadays, more and more people use the digital display dynamometer, so there will be more and more small problems in the digital display dynamometer. Therefore, today I will tell you how to solve the inaccurate test accuracy of the digital display blood pressure monitor.
What to do if the digital display blood pressure monitor test accuracy is not accurate:
1. No return to zero (no return to zero, no weighing)
2. Check the sensor If the output signal value is within the standard. (Total magnification size of A/D/Used inner size range/Lower size range)
3. If it is not within the standard, please refer to the tenth item for compensation.
4. If it cannot be compensated, please check if the sensor is faulty. (Please follow the eighth item for the test)
5. Please follow the i10 ton digital tension meter instructions for performing tension calibration.
6. Observe whether the trainee\'s al code value is stable, whether there is friction in each part of the sensor, whether the regulated power supply is stable, whether the operational amplifier circuit is normal, if there are foreign objects on the A/D circuit PCB, if the feedback resistor/if the capacitor/filter capacitor is bad or leaking.
7. Check if the sensor output signal value is within the standard.
8. Use weights to test whether the pulling force is average.
9. The battery cannot store electricity
10. Please make sure it is not caused by the fuse, power switch, line electric and the voltage switch.
11. Check if the transformer has AC110/220 input and AC18V output.
12. Remove the battery from the PIN on the carte and measure whether the machine board load voltage is about 7.2V. If it is not enough, please check the circuit related to the power supply.
13. Check the version of the machine, if the diode near the pin at the input end of the transformer is normal.
14. Replace the battery.
15 Judgment of defective sensor a Static measurement method:
16. Perform frequent maintenance and servicing, and store in a dry and ventilated place. If the standby time is too long, it should be turned on regularly. Prevent moisture and mildew from damaging the digital display dynamometer parts. 17. Be careful not to overload the sensor of the digital display blood pressure monitor when using
