三、混凝土快速养护箱使用方法：

★箱体安放平稳后，**先检查电器部分有无原件损坏，线路是否接触良好，插好传感器和加热器插头。设备必须有可靠接地。 　

★开箱加水高约60mm。试块成型后，常温存放7小时或标养3小时，观察接近终凝时，（根据水泥成分不同，应自行注意观察，接近终凝时间）随同试模一起放入箱内搁架上。 　　

★盖好箱盖，插好温度传感器，根据各厂水泥成分不同，设定温度和工作时间。

★ 试验结束，取出试模放置常温处，到试块恢复常温时，拆开试模，取出试块，即可进行抗折、抗压试验。

★试验结束后，放水并擦干内箱。

★根据水泥种类不同，可采用恒温65-80℃之间进行，标准与快速对比试验10-20次，找出比值或差值，得出标准检验结果

★温度设定 

温控仪通电后，上排显示为当前箱体内温度，下排显示设定温度。此时，可用“∧”，“∨”键设定温度值。绿灯亮表示开始加温，闪烁表示恒温状态。 长期使用后，传感器出现零点漂移，当漂移超出试验要求范围，则需调整。具体操作如下：按下“SET”键3秒，温控仪进入参数调整状态，此时，上排显示所调整的项目，下排为对应数值，继续点动“SET”键，直到上排显示“SC”，此时可按“∧”，“∨”键，调整下排数值，进而修正正负偏差。其它参数不建议修改，如须修改，请参照所附温控表使用说明书。 

★混凝土快速养护箱时间设定 

接通电源后，4位数码管显示“00：00”，按“设置/查询”按钮，此时被设定位开始闪烁，可按“加数”按钮置数，按“移位”键可设定下一位数（从左到右）。设定好时间后按“启动”键，设备开始工作，计时从0开始，到达设定时间后，蜂鸣器响，提示保温时间到，可取出试块。试验中，当操作人员想查看设定时间为多少时，可按下“设定/查询”键，数码管显示设定时间，再次按下“设定/查询”键，设备继续工作，（查询后不能按“启动”键）。定时结束后按下“设定/查询”键即可令蜂鸣器停响。

Third, the use of rapid concrete curing box:

★ After the cabinet is installed smoothly, first check the electrical parts for damage to the original parts and whether the lines are in good contact. Plug the sensor and heater plugs. The equipment must be reliably grounded.

★ Unpacking and adding water is about 60mm high. After the test block is formed, it is stored for 7 hours at room temperature or 3 hours at standard temperature. When it is observed to be near the final setting, (depending on the composition of the cement, you should pay attention to it and approach the final setting time).

★ Close the lid of the box, insert the temperature sensor, and set the temperature and working time according to the cement composition of each plant.

★ After the test, remove the test mold and place it at normal temperature. When the test block returns to normal temperature, disassemble the test mold and remove the test block to perform the flexural and compressive test.

★ After the test, drain the water and dry the inner box.

★ Depending on the type of cement, constant temperature 65-80 ° C can be used. Standard and rapid comparison tests 10-20 times, find out the ratio or difference, and get the standard inspection results.

★ Temperature setting

After the temperature controller is powered on, the upper row shows the current temperature inside the cabinet, and the lower row shows the set temperature. At this time, you can use "∧" and "∨" keys to set the temperature value. The green light is on to indicate the start of heating, and the flashing indicates constant temperature. After long-term use, the sensor has zero drift. When the drift exceeds the range required by the test, it needs to be adjusted. The specific operation is as follows: Press the "SET" key for 3 seconds, the temperature controller enters the parameter adjustment state. At this time, the upper row displays the adjusted item, and the lower row is the corresponding value. Continue to jog the "SET" key until the upper row displays "SC", at this time, you can press the "∧" and "∨" keys to adjust the lower row value, and then correct the positive and negative deviation. It is not recommended to modify other parameters. If you need to modify, please refer to the instruction manual of the attached temperature control meter.

★ Time setting of rapid concrete curing box

After the power is turned on, the 4-digit digital tube displays "00: 00", and press the "Set / Query" button. At this time, the set bit starts to flash. You can press the "Add" button to set the number, and press the "Shift" key. Set the next digit (from left to right). After setting the time, press the "Start" key, the device starts to work, the timing starts from 0, when the set time is reached, the buzzer sounds, indicating that the holding time is up, you can remove the test block. In the test, when the operator wants to check the set time, he can press the "Set / Query" key, the digital tube displays the set time, press the "Set / Query" key again, the device continues to work, (Query You cannot press the "Start" key afterwards). After the timer is over, press the “Set / Query” button to stop the buzzer.

四、混凝土快速养护箱安全注意事项：

★加速养护箱盖在使用过程中请勿倒放(可依箱盖上提示标牌文字正视位置为准)。

★放置试件时应留测温探头的对应位置，以免探头插入时损坏。

★ 试件在放入和取出时一定要注意安全，即在使用专用工具钩起试件时必需确认工具钩是否已稳稳地钩牢试件，以防操作中途试件脱落箱内热水飞溅伤人。

★ 加速养护箱使用结束后必须切断电源，防止电热管无意中尚处于加热状态，造成脱水损机现象。

★加速养护箱长期不用时需将水放尽擦干，放在通风干燥处。

Fourth, safety precautions for rapid concrete curing box

★ Do not place the cover of the accelerated curing box upside-down during use (you can follow the position of the label on the box cover).

★ The corresponding position of the temperature probe should be kept when placing the test piece, so as to avoid damage when the probe is inserted.

★ When putting in and taking out the test piece, please pay attention to safety, that is, when using the special tool to hook up the test piece, you must confirm whether the tool hook has firmly hooked the test piece to prevent the test piece from falling off in the middle of operation. Hurt.

★ After the accelerated curing box is used, the power must be cut off to prevent the heating pipe from being inadvertently heated, which will cause dehydration and damage to the machine.

★ When the accelerating curing box is not used for a long time, it is necessary to dry the water thoroughly and put it in a dry and ventilated place.
