19. Sensitivity: The ratio of the output increment of the sensor to the corresponding input increment.
20. Sensitivity drift: The change of the slope of the calibration curve caused by the change of sensitivity 21. Thermal sensitivity drift: The sensitivity drift caused by the change of sensitivity
22. Thermal zero drift: Zero drift caused by the change of ambient temperature

24. Nonlinearity: The degree to which the calibration curve deviates from a regular straight line
25. Long-term stability: the ability of the sensor to still insist on not exceeding the promised error within the regular time.

28. Compensation Temperature Scale: The temperature scale compensated by the zero balance between the sensor scale and the rule limit.
29. Creep: When many environmental conditions persist in the same condition, the change of the output of the machine under test within a regular time.
30. Insulation resistance: Unless otherwise specified, it refers to the resistance value measured between the regular insulation parts of the sensor when a regular DC voltage is applied at room temperature.
