偏差发生的根本原因是校准人员陈宏伟因疏忽大意未将温度计插入匹配的温度套

The root cause of the deviation is that the calibration staff Chen Hongwei negligently failed to insert the thermometer into the matching temperature sleeve, and H0-TM-21224 "Automatic Control System Temperature Calibration Regulations" did not specify in detail which thermometers correspond to which types of temperature sleeves. <br><br>The mismatch between the thermometer and the temperature sleeve causes the actual error to exceed the allowable error. When recalibrated, the temperature sleeve is replaced with a matching temperature sleeve. The calibration result is qualified. At the same time, the thermometer is removed and placed in the dry body furnace when the 201 can is empty The heating is carried out in the middle, so it does not involve the actual temperature measurement of the tank body, and it will not affect the completed production batch. <br><br>CP-TZ-API-D-TZ-API-EG-19005-20001. Replace the thermometer of Y 201 fermentation 201 tank in workshop 109 with matching temperature sleeve for annual calibration. <br>CP-TZ-API-D-TZ-API-EG-19005-20002. Revision H0-TM-21224 "Automatic Control System Temperature Calibration Regulations" version 02, add "the temperature needs to be put into the thermometer calibration process in the thermometer calibration process" Sleeve, if there is no matching temperature sleeve, it is necessary to add silicone oil, thermal grease and other thermally conductive substances to the temperature sleeve of the dry body furnace ", detailed list of the thermometer and temperature sleeve model comparison table, and training relevant personnel .

The root cause of the deviation is that the calibrator Chen Hongwei inadvertently failed to insert the thermometer into the matching temperature sleeve, and h0-TM-21224 "self-control system temperature calibration procedures" does not specify which thermometers correspond to which models of temperature casing. <br><br>The mismatch between the thermometer and the temperature casing results in the actual error exceeding the permissible error, replaced with a matching temperature sleeve when recalibrated, the calibration results are qualified, and because the thermometer is removed and put into the dry body furnace for heating and heating when 201 cans are empty, it does not involve the measurement of the actual temperature of the tank body, and will not affect the completed production batch.<br><br>CP-TZ-API-D-TZ-EG-19005-20001. Annual calibration is performed for the replacement of thermometers for 109 workshopY10 fermented 201 cans using a matching temperature casing.<br>CP-TZ-API-D-TZ-API-EG-19005-20002.Revised H0-TM-21224 Version 02 of the Self-Control System Temperature Calibration Procedure, added to the thermometer calibration process "The thermometer calibration needs to be placed in a matching temperature casing, such as no matching temperature casing must be added to the temperature casing of the dry body furnace silicone oil, hot fat and other thermal materials", detailed list of thermometers and temperature casing model control table, and training of relevant personnel.

The root cause of the deviation is that the calibrator Chen Hongwei didn't insert the thermometer into the matching temperature casing due to negligence, and h0-tm-21224 temperature calibration specification for automatic control system didn't specify which thermometer corresponds to which model of temperature casing.<br>The mismatch between the thermometer and the temperature casing results in the actual error exceeding the allowable error. When recalibrating, the thermometer is replaced with the matched temperature casing, and the calibration result is qualified. At the same time, the thermometer is removed when the tank is empty and put into the dry body furnace for heating, so the actual temperature measurement of the tank body is not involved, and the completed production batch will not be affected.<br>Cp-tz-api-d-tz-api-eg-19005-20001. The thermometers of fermentation tank 201 in building Y10 of workshop 109 were replaced with matching thermowells for annual calibration.<br>Cp-tz-api-d-tz-api-eg-19005-20002. Revised version 02 of h0-tm-21224 temperature calibration procedure for automatic control system, adding "matching temperature casing is required during thermometer calibration, if there is no matching temperature casing, silicon oil, thermal grease and other heat conducting substances must be added into the temperature casing of dry body furnace", and detailed model comparison table of thermometer and temperature casing is listed And train relevant personnel.
