Bridge connection: 1x40Watt@8OhmThe Mini Digital Amplifier has the bridge connection, to double the output power at******************************************************************** mono output, and the power is up to 40Watt.The bridge connection is:Connecting the two pins, like thisConnecting the four pins, like this2.1.3. Dual-mono OutputThe Mini Digital Amplifier also has the function of double-mono output. It can sum up the left and right channel, to be the mono audio output. In this way, the both of the outputs are showing the same mono audio.The connection is:2.2. Microphone input The microphone input of Mini Digital Amplifier has three modes, and different modesuse different connections, as the picture below:2.2.1. 48V phantom power inputWhen the switch turns to “48V”, the MIC input will provide a 48V phantom power. This is usually used for power supply for condenser microphone, Connection is: “+” connects to positive, “-” connects to negative and “╧” to ground.Note : In this mode, only condenser microphone can be connected with.2.2.2. MIC inputWhen the switch turns to “MIC”, the microphone input is used for connecting with dynamic microphone. There are two different connections:1) Unbalanced connection:“╧” connects to ground, and “-” connects to signal.“╧” connects to ground, and “+” connects to signal.2) Balanced connection: “+” connects to positive, “-” connects to negative and “╧”connects to ground.2.2.3. LINE inputWhen the switch turns to “LINE”, the microphone input is used for connecting with normal audio or wireless microphone output. There are two different connections:Connecting the four pins, like this1) Unbalanced connection:“╧” connects to ground, and “-” connects to signal.“╧” connects to ground, and “+” connects to signal.2) Balanced connection: “+” connects to positive, “-” connects to negative and “╧”connects to ground.Operation of the Control Panel and the IR Remote3.1.

VAPRO_5520组织渗透压计使用说明
VAPRO 5520组织渗透压计使用说明建议首次使用此仪器时遵照以下流程进行操作：1、检查各种配件和耗材是否齐全2、将仪器放置在合适的工作环境中，平坦桌面上避免震荡3、待仪器温度和环境温度适应达到平衡后，插上电源连接线，打开仪器开关（仪器工作环境温度范围：15-35o C）4、装样校准仪器，注：使用标准溶液的顺序为:290mmol/Kg,1000 mmol/Kg, 100 mmol/Kg,标准液为一次性消耗品，每次不管剩余多少都要扔掉5、进行热电耦清洁测试，如果达不到要求需要对热电耦进行清洗6、判断仪器是否校准合格，若不合格，需再次进行校准，必要时对热电耦进行清洗（清洗步骤详见说明书P46-P56）。
7、以上步骤完成后即可载入样品进行测试。
相关细节及注意事项总结如下：1、如何载样？具体参照仪器使用说明书P36-38。
注：每次只能放置1个载样纸片，放置多个会导致测试结果偏高。
移液枪量取液体体积：10ul，允许偏差范围：10%，多于11ul可能会污染测量室内的细微热电耦。
需要注意的地方：可以用移液枪枪头尖端轻轻压平载样纸片，载样过程操作动作最好迅速，及时把样品槽推进测量室内，防止水分的挥发而影响测量的准确度。
2、每次测完样品后如何清洗载样槽？清洁工具：棉布或丝绸，不能用面巾纸或者纱布擦拭。
擦拭之后若还有残余物，需要用专用清洗液进行清洗。
3、载样槽清洗过程中应该注意的地方？不可用手触摸载样槽，每次测定之后不能用镊子等金属工具取出载样纸片。
尽量缩短清除残余样品的时间，并尽快加样进行测试。
4、载样槽清洗的标准？擦拭明亮，完全干燥，然后才能加下一个样品。
5、如何进行校准？注：使用标准溶液的顺序为:290mmol/Kg→1000 mmol/Kg→100 mmol/Kg,标准液为一次性消耗品，打开安剖瓶盖之后的几个小时内标准液可以使用，之后每次不管剩余多少都要扔掉。
（安剖标准液瓶直接用手轻掰即可打开，打开过程要小心，注意别伤到手指）3种标准液校准时允许的偏移幅度分别为290mmol/Kg--+3 mmol/Kg,1000 mmol/Kg--+5 mmol/Kg, 100 mmol/Kg--+2 mmol/Kg。

五、电梯运行状态的调试。 5．1 将电梯运行到中间楼层，然后进入轿厢，使电梯工作在有司机状态下、直驶状态下，试试电梯的运行状态，检查 是否正常。 5．2 将“开放功能选择”中的“司机时不理外召”功能打开，再进入监控画面第三页，按“换行”按钮，直到旁边出 现“选层” 、 “内召”字样为止，然后通过按动按钮给予主控板内指令信号，使电梯关门、启动、运行、换速、 平层、再开门。 六、 在电梯运行正常情况下，首先调整电梯的舒适感。 6．1 觉得电梯运行的舒适感不够理想，首先应检查系统的机械情况，如导靴的间隙，导靴的润滑，钢丝绳的松紧度是 否均匀等，这些都会影响电梯运行的舒适感。机械部份经检查没有问题后，才可对控制部份进行调整。 6．2 由于变频器是按给定的起、制动曲线来控制电动机的运行，因此给定的起、制动曲线形状，变频器控制的电机反 馈速度对曲线的跟踪程度及控制单元发给变频器控制信号的时序都将影响电梯运行的舒适感， 此时可重点调整变 频器中的 C1-01，C1-02，C1-03，C1-04，C1-06，C5-01，C5-02， C5-03 等参数，主控板的参数：起动零速时间一、起动零速时间二、停止零速时间一、停止零速时间二等。 6．3 让电机在最高输出频率运转。 6．3．1 逐渐调整起动零速时间一、起动零速时间二、停止零速时间一、停止零速时间二的值,以达到最好的运行舒适 感. 七、平层精度的调整 7．1 平层精度的调整应在舒适感调整完毕后进行，准确平层首先要保证轿顶光电（永磁）感应器及隔磁板的安装位置 十分准确，即当轿厢处于平层位置时，隔磁板的中心点必须与中间一个光电（永磁）感应器的中心点重合，并 且隔磁板与光电（永磁）感应器的面要垂直。 7．2 首先调整楼层的平层精度，当电梯每次向上运行时，轿厢地坎高出厅门地坎而当电梯每次向下运行时轿厢地坎低 于厅门地坎，则可减小变频器 D1-03 的数值，反之即增加。直到 D1-03 的值调整至最合适的值为止。 7．3 楼层的平层精度调整，也可通过更改距离参数菜单中的： “上零速指令距离”和“下零速指令距离”的数值来达 到目的。 如果上行时轿厢高出地坎，则减小“上零速指令距离”的数值，否则加大“上零速指令距离”的数值； 如果下行时轿厢高出地坎，则加大“下零速指令距离”的数值，否则减小“下零速指令距离”的数值， 。 7．4 最后仔细核对各个功能（比如：司机、满载、超载、到站钟、到站灯、并联、群控等）是否正确，如果正确,则 整个调试工作结束。 八、安装调试注意事项 8．1 操作变频器时,切勿动梯，否则有溜车的危险。 8．2 插接外呼面板时，一定要小心，切勿错位，否则面板将烧坏。 8．3 外呼面板的楼层地址码必须上锁，密码统一为 5。 8．4 紧急电动运行时，自动短接了安全回路中的：安全钳开关、限速器开关、极限开关及缓冲器开关，所以尽量不要 短接安全回路开关，如果在特殊情况下需要短接，则完工后定要恢复。 8． 5 检验电梯的绝缘时，必须把主控板上的所有插头都拔出，另外无机房电梯控制柜与应急松闸电源装置的连接线 必须拔出，另外，控制柜后面接线端子 PE 上的线卸开，验完后恢复。

FBG-5210(5220)_应变计安装使用手册-自带温补
FBG5220表面安装式图5、 FBG5220表面安装示意图FBG5220表面安装传感器的安装相对简单。
它有二种安装座，如图3.1、图3.2,安装到混凝土表面可以采用如下方式：1．将传感器同底座安装到一起后，观察并调整两边的底座是在同一平面上，初步上紧两边的四个顶丝。
2．在需要安装的混凝土表面涂上环氧胶（或快干胶），并在底座的底部涂上环氧胶（或快干胶），然后将整个传感器放到混凝土表面，底座处适当加力均匀放到混凝土表面，用胶带初步固定。
3．待环胶氧（或快干胶）充分固化后，用力拧紧四个顶丝。
4．观察并记录传感器的计数。
2.4. 光缆保护和终端连接从应变计引出来的光缆可使用柔性软管来保护，公司可接受该种柔性保护管的订货。
光缆可拼接加长而不影响传感器读数。
要保持接头完全清洁。
光缆终端的FC/APC光学接头可通过一0.5米的跳线与光纤光栅分析仪相连，多芯光缆可通过一终端盒与光纤光栅分析仪相连。
3.读数光纤光栅分析仪是所有光纤光栅传感器获取读的仪器。
将连有光纤光栅传感器的光纤通过FC/APC光学接头即可接入光纤光栅分析仪，打开光纤光栅分析仪软件对传感器进行扫描即可读出传感器的当前波长值，光纤光栅分析仪的具体应用详见相关光纤光栅分析仪的使用说明书。
FBG-5210T（温补型）传感器内部都配有测读温度的光栅，随着温度变化，测温光栅的波长也变化，通过测温光栅波长的变化值可以得知温度的变化量。
FBG-5200（非温补型）传感器内部不配有测温度的光栅，但是可以在传感器外部单独放置一个温度传感器，以用作温补。
4．数据处理应变计波长读数转换成微应变可通过理论公式计算。
由于传感器本身存在温度影响系数 B，因此由于仪器温度影响而修正的混凝土总应变可由下面的公式计算出。
ε总 = k1(λ-λ0)+ B(λt1-λt0)上面的公式中包括混凝土中温度引起的应变，加上荷载变化引起的应变。
在无荷载区域温度引起的混凝土应变可由下面的公式计算出来；ε温度= (λt1-λt0) *αA*108其中αA代表混凝土温度膨胀系数，因此，下面公式用于计算仅仅因荷载变化引起的混凝土应变；ε=K(λ1-λ0)-B(λt1-λt0)K为应变计应变系数（με/nm）(取正值)Ｂ为温度修正系数，B= K+43.5(αA-αB)*106,单位取με/nm。
