Press ‘Scan fordevices’.Once your instrument has been discovered,press on its name to connect to it.Optimus sound level meter - Bluetooth and dBActive quick start guide6Enter the code from your Optimus+ into yourmobile device and press ‘Pair’.Before your Optimus+ can connect to your mobile device, you will be asked to input a code that will be displayed on the Bluetooth menu screen.Your Optimus+ will now be paired with your mobile device. You will see the default home screen on the dBActive app, which displays live noise measurement information. From this screen, you will be able to navigate around the app, which will be described in the coming pages.Optimus sound level meter - Bluetooth and dBActive quick start guide 72 Using your Optimus+ with your mobile device throughdBActive This screen is the default home screen for dBActive and displays live noise data for a number of parameters, each of which can be changed. Press the arrow on the value you wish to change. A menu will appear allowing you to select the value you wish to see (see image below).2.1 Viewing live dataOne of the key features of dBActive is the ability to view live noise data remotely. Thisinformation can be viewed in a number of different ways, which are outlined below:2.1.1 Using the overview screenPlease note: some noise parameters are unavailble on certain variants of the Optimus+.8Optimus sound level meter - Bluetooth and dBActive quick start guide2.1.2 Using the live data screenThis screen displays live noise data for any twochosen parameters (which can be changed bypressing the arrows on the chosen parameter).The graphs refresh every second and provide avisual representation of the noise levels whereyour Optimus+ is measuring.2.1.3 Using the octaves screenThis screen displays live data for 1:1 octavebands.Optimus sound level meter - Bluetooth and dBActive quick start guide9From the overview screen, choose either ‘Start measuring’ or ‘Start measuring/audio’ to begin a measurement. If you choose ‘Start measuring/audio’, the measurement will include an audio recording of the noise. If you choose ‘Start measuring’, audio will not be recorded.Please note: audio recording can be switched on/off manually during a measurement using the option above the start button. Audio recording is only available on certain variants of the Optimus+.2.2 Starting and stopping a measurement As well as being able to view live noise data, dBActive allows you to start and stop noise measurements remotely, meaning that your Optimus+ can be used in potentially hazardous and/or difficult-to-access areas.2.2.1Starting and stopping a measurementWhen a measurement is in process, the red start button changes to a green stop button. Press this to endyour measurement.If you need to highlight a specific event during a measurement for when you come to review your data in the NoiseT ools analysis software (supplied with your Optimus+), press ‘Mark measurement’ when a measurement is in process.2.2.2Marking a measurementA confirmation box will appear at the bottom of the screen to let you know that the measurement has been marked.Optimus sound level meter - Bluetooth and dBActive quick start guide10This screen displays the data for all main noise parameters. You can cycle through measurements by using the arrows at the bottom of the screen.2.3 Reviewing measurement dataThe ‘Measurements’ screen allows you to review previous measurement data for the connected instrument. This includes both measurements that have been made on dBActive and those that have been made natively on your Optimus+.2.3.1Reviewing measurementsIf you’re experiencing issues downloading your measurement data or the app is displaying measurements from a previously connected instrument, press ‘Retry’ to refresh the informationdisplayed.If you want to share measurement data, press the ‘Share’ button.2.2.2Sharing measurement dataA popup box will appear listing the options available. The measurement data will be shared as a text-only list, which you will then be able to edit as you wish.Please note: sharing options will vary depending on the operating system of your device and the third-party applications you have installed.Please note: you must ensure that any measurement data you wish to keep is either stored on your Optimus+ or downloaded to a PC using NoiseT ools. Measurement data is not permenantly stored in dBActive and will be overwritten once a different instrument is connected to the app.Optimus sound level meter - Bluetooth and dBActive quick start guide112.4 Changing your instrument’s settings 2.4.1 Changing the date and timePress on the existing option to open a menu, from which you can select a new value.2.4.2 Changing time history rateWhen using your Optimus+ remotely, you can change some of its settings via dBActive on the ‘Settings’ screen.From this menu you can change the date/time of your instrument, time history rate, audio quality, and timer settings. You can also turn audiotriggers on/off.Press ‘Sync with device’ to syncronise your instrument’s date/time setting with that of yourmobile device.Once complete, a notification will display at thebottom of the screen.Optimus sound level meter - Bluetooth and dBActive quick start guide 12Press on the existing option to open a menu, from which you can select a new value.Standard quality (16-bit, 16 kHz)High quality (24-bit, 48 kHz)Studio quality (32-bit, 96 kHz)2.4.3Changing audio qualityPress on the existing option to open a menu, from which you can select a new value.Repeat timer - allows measurements to be stopped and started automatically over a long period of time. The repeat tim er is synchronised2.4.4Changing timer settingsPress on the switch to either turn audio triggers on or off.Anaudiotrigger will start your instrument recording the audio and noise levels when a certain threshold has been met. This setting can be customised on your Optimus+.A confirmation message will display after the setting has been selected.2.4.5 Turning audio triggers on/offto the real-time clock, so if you choose a 30 minute duration, the measurement will begin on the hour and at 30 minutes past. When the measurement ends, a new one will begin and last for the next 30 minute interval.Single timer - The single tim er allows m easurem ents to autom atically stop after a pre-defined period of tim e. If you set the single tim er duration to 15 m inutes and enable the single timer option, then all measurements will automatically stop after 15 minutes.Optimus sound level meter - Bluetooth and dBActive quick start guide132.5 Viewing information about your instrument The last screen in dBActive displays information about your Optimus+ instrument.a. current battery levelb. % free space for measurement datac. % free space for audio recordingsd. number of measurements saved on your instrumente. your instrument’s typef. unique serial number for your instrumentg. firmware version installed on your instrumenth.microphone information (model and serial number) i.preamplifier information (model and serial number)j. offset value based on the last calibration of your instrument and the date/time it was last calibrated k.full list of capabilities/features of your instrumenta b c d e f g h ij k• Bluetooth® enabled• Can be operated through asmartphone app• Includes 1:1 octave band filters• Custom timers can be used forscheduled measurements• New discreet designSimplicity redefined• Noise-activated warning sign• Alerts employees as to when PPEis required• Various messages available• Different languages available• Custom noise level trigger can be setCreating safer environmentsCirrus hold UKASContact our sales team for more information************************。

登士柏protaper操作流程Protaper根管预备操作流程{一}一、开髓和修整髓腔可选用的车针：开髓:Endo Access Bur (A0164)用Endo Z(E0152) 或Diamendo修整髓腔形态，以获得直线通道。

Diamendo (A0165)说明：先用Endo Access bur开髓、去髓顶；再用Diamendo或Endo z修整髓腔，去除牙本质领，建立到根管口的直线通道。

“直线通道”非常重要！1.使视野清晰，便于找到根管口，2.能保持根管器械进入根管前不被弯曲，大大减少器械发生旋转疲劳(Cyclic fatigue)，减少断针机率，延长根管器械使用寿命。

国外要求镍钛根管锉针只能使用一次，但我们不可能做得到，因此尽量减少器械劳损是节省成本的唯一办法。

车针再贵也不及一根锉贵吧？所以建议您使用好的车针进行开髓和髓腔预备3.Diamendo和Endo Z尖端无切割力，能较好的避免意外的侧穿或底穿。

这两根车针都比较贵，但从降低操作难度和风险来讲，这个还是值得的。

4.修整完成后，有时根管口被钙化物等阻挡而难以找到根管口时，需用长颈球钻(LN bur)或是专用的超声头来去除钙化物以找到根管口，切忌盲目过度切割!! Proultra 1-5号超声头用于去除根管口的阻挡非常好,但成本太高,在国外也只有根管专家才用。

这些操作多数只能在直视下操作，对于多数没有根管显微镜的医生来讲，都不太容易。

二、探查根管: 可选用DG 16根管口探针(B0093)在拔除根髓前最好用专用的根管探针对根管口进行探查，确认根管开口的位置和根管口敞开的程度。

DG16尖端细小、弹性好，能很好的传递应力，是被编写教科书的专家们推荐使用的经典根管探针。

另外，还有专用来探查根管通道的Profinder,由登士柏迈斐(Dentsply Maillefer)生产，最早明年能在国内上市。

它采用特殊钢材，特独特的减锥度设计以获得适宜的弹性，其尖端直径分别为10#,13#,17#。
