When reinstalling enclosure screws they must be tightened to 9 in-lb +/- 10%.Switching On Your DPG409 MeterBefore you connect your USB cable to the USBprogramming connector on the DPG409, you will need to switch on the unit.Setting Up Your MeterConnect the USB Programming cable included with your unit to your PC and your meter.USB Connector LocationNow that you have connected your USB cable to your PC and to your meter, you can now configure yourmeter before placing the unit into operation. You will be using the configuration software utility that you installed onto your PC. If you have not installed the configuration software utility you should do so now.Configuring your MeterThe Omega Digital Gauge Configuration Wizard will open once you have launched the DG Configuration Wizard software. Follow the step-by-step instructions given to you by the Configuration Wizard. Step 5 - Choose Options: Select the type of analog output your application requires. You can leave the default setting if of your meter to match the analog output type you selected here in the setup process.WGS/START HERE ARROWGS/START HERE ARRO 2WGS/START HERE ARRO34Using This Quick Start ManualUse this Quick Start Manual with your DPG409 Series high accuracy digital pressure gauge for quick installation and basic operation. For detailed information, refer to the User’s Guide available at https:///manuals/manualpdf/M4978A.pdf.General DescriptionOmega’s DPG409 Series Digital Pressure Gaugesincorporate rugged, 316 Stainless Steel enclosures that are designed specifically for wash-down,sanitary and marine applications. The large backlit LCD display features 1" high digits that make reading at distances up to 35 feet easy. Models are available with integral standard or sanitary pressure sensors that incorporate highly stable silicon wafer technology which is micro-machined to precision tolerances and then has strain gauges molecularly embedded.The DPG409 is NEMA 4X rate (water tight, dust tight, corrosion – resistance - indoor & outdoor use). The pressure gauge can be installed inlocations where it will be intermittently exposed to spraying water, rain or high humidity. The meter should never be used under water.Software InstallationDownload the Configuration Wizard software from ftp:///public/DASGroup/products/dpg409/. To install run the setup.exe application. The installer will guide you through the steps required to install the DG Configuration Wizard on your computer.Lid/Cover RemovalTo switch on your unit and access the USB programming connector on your meter, theenclosure lid/cover must be removed. Four screws must be removed. Be careful to not lose or discard these screws. These screws play a vital part inproviding the water tight seal on your unit.Lid/Cover RemovalWiring (Power, Analog Output)Wiring - Power SupplyWiring - Analog OutputFor alarm wiring information refer to the User's Guide, Page 4-4, Figure 4-5.Keypad Operation Magnetic StylusA magnetic stylus is attached to your meter. This stylus is used to activate the front buttons on the display. If you do not need to view the “MIN”, “MAX” or “AVERAGE” readings during normal operation, or have a need to turn the backlight on during normal operation you can remove and store this stylus. You will need to select “Disable Keypad” during the setup and configuration process.The “MODE” and “SET” buttons located on the front of the display of your meter areactivated by waving or tapping the magnetic stylus included with your unit above or onto the keypad button symbol on the front meter label.REMOVE THESE FOUR SCREWSIN ORDER TO REMOVE THE METER FRONT COVERAnalog Output OptionsInstallationMountingFor mounting dimensions refer to the User’s Guide, Page 4-1, Figure 4-1.Ambient TemperatureYour meter should only be installed in locations that maintain an ambient temperature between -18 to 66°C (0 to 150°F).Battery Installation/ReplacementTo install or replace the battery in your DPG409pressure gauge you must first remove the four screws located on the Lid of the enclosure. This will allow you to remove the meter assembly and access the battery operation (Battery 1). A second battery (Battery 2) can be added to extend operation when on battery power. It is also recommended that the additional battery (Battery 2) be installed for models that include the optional wireless transmitter.Battery PlacementTB1CHART RECORDER+–45PIN 1。

精密数字压力计使用注意事项压力计如何操作精密数字压力计的内部结构是特别精密的，我们在使用的过程中有很多需要注意的地方，往往一个错误的使用方法会导致产品损坏大量的机能，甚至导致产品报废。

今日我们精密数字压力计的内部结构是特别精密的，我们在使用的过程中有很多需要注意的地方，往往一个错误的使用方法会导致产品损坏大量的机能，甚至导致产品报废。

今日我们就来实在介绍一下精密数字压力计的使用注意事项，希望可以帮忙用户更好的应用产品。

（1）精密数字压力计装在锅炉、压力容器上的数字压力表，其最大量程（表盘上刻度极限值）应与设备的工作压力相适应。

精密数字压力计的量程一般为设备工作压力的1.5～3倍，可以取2倍。

若选用的数字压力表量程过大，由于同样精度的精密数字压力计，量程越大，允许误差的确定值和肉眼察看的偏差就越大，则会影响压力读数的精准性；反之，若选用的数字压力表量程过小，设备的工作压力等于或接近精密数字压力计的刻度极限，则会使数字压力表中的弹性元件长期处于最大的变形状态，易产生永久变形，引起精密数字压力计的误差增大和使用寿命降低。

另外，精密数字压力计的量程过小，万一超压运行，指针越过最大量程接近零位，而使操作人员产生错觉，造成更大的事故。

因此，精密数字压力计的使用压力范围，应不超过刻度极限的60～70%.（2）工作用数字压力表的精度是以允许误差占表盘刻度极限值的百分数来表示的。

精度等级一般都标在表盘上，选用精密数字压力计时，应依据设备的压力等级和实际工作需要来确定精度。

（3）表盘直径为了使操作人员能精准地看清压力值，数字压力表的表盘直径不应过小，假如数字压力表装得较高或离岗位较远，表盘直径应增大。

（4）精密数字压力计用于测量的介质假如有腐蚀性，那么确定要依据腐蚀性介质的实在温度、浓度等参数来选用不同的弹性元件材料，否则达不到预期的目的。

（5）日常重视使用维护，定期进行检查、清洗并做好使用情况记录。

（6）精密数字压力计一般检定周期为半年。
