Anderson Instrument Co., Inc.156 Auriesville Rd. ~ Fultonville, NY 12072Phone: 518-922-5315 ~ Fax: 518-922-8997Installation and Startup GuideDigital Pressure Gauge & SwitchVersion 1.4 Document 2052PRODUCT DESCRIPTIONThe Anderson Digital Pressure Gauge platform is designed specifically for monitoring critical pressures in sanitary applications. The product line was developed to addressseveral trends relative to performance, safety, and readability criteria of our core customers. The Anderson Digital Pressure Gauge provides a battery-powered, local display of pressure that is 6 times more accurate than its mechanical counter-part. Additionally, this product has 3 times the over-range capacity and 5-10 times the resolution of traditional mechanical pressure indicators. The switch version includes 2 fully adjustable switches with low-voltage relay outputs for simple control and/or alarming applications.SPECIFICATIONSPerformance Accuracy: ±0.2% of transducer URL (30, 100, 200, 300, 500 psi)±0.5% of transducer URL (5 psi)Complies with ASME B40.7-1998Repeatability: ±0.06% of transducer URL (30, 100, 200, 300, 500 psi)±0.2% of transducer URL (5 psi)Temperature stability: ±0.10 psi / 10ºF change in process orambient Over-range Capacity:2X URLOperationalProcess Temp Limits: -4º to 127ºC (25º to 260ºF) continuousAmbient Temp Limits: 4º to 49ºC (40º to 120ºF)Engineering Units: Programmable by user, see matrix for pound ranges: Full Vacuum to selected positive pressure.

When a low threshold is reached, the final indicator bar blinks on and off. Internal circuitry regulates battery voltages to ensure all factory specifications are met, even with a decrease in battery voltage. When an unacceptable level is reached, the DPG will shut down. Internal flash memory retains all prior calibration, and only replacement of the batteries is required to resume operation.RUN Mode(read values only)Normal Display: Pressure & UnitsAlarm Setpoint and ActionAlarm 1 Hysteresis Alarm 2 Setpoint and ActionAlarm 2 Hysteresis Low Range Limit Upper Range Limit Dampening FactorMaximum Captured Pressure Minimum Captured Pressure Calibration Offset Value Calibration Gain ValueSETPOINTS Mode (modify alarm values)Alarm 1 Setpoint ValueAlarm 1 Action Alarm Hysteresis Alarm 2 Setpoint ValueAlarm 2 Action Alarm 2 HysteresisCALIBRATE Mode(modify field calibration parameters)Calibration Offset Calibration GainPressure Units DisplayedDampening Factor Decimal Point Position Maximum Pressure Captured Minimum Pressure Captured Restore Factory ConfigurationBATTERY REPLACEMENTUSER DISPLAYVALUE Switch UP to increase DOWN to decrease MODE Switch UP for SETPOINTS DOWN for CALIBRATIONDigital Gauge shown with back removed to expose batteries and switches.MENU Switch UP for SCROLL FWD DOWN for SCROLL BACKPrimary Process Display Four digit 0.9” LED with adjustable decimal point position to indicate pressure value.Alarm 1 and 2 Indicators Flashes if setpoint tripped.Displays continuouslyduringsetpoint viewing or programming.Battery Status Indicator Three bars indicatebattery condition is good.Secondary Display Indicates pressure units or parameter information.ALARM SETPOINT PROGRAMMING(MODE Switch in the UP Position)CALIBRATION / CONFIGURATION PROGRAMMING(MODE Switch in the DOWN Position)PSI Gau, PSI ABS, in 2H 0, Kg/cm , mmHg, 2inHg, MP a, kP a, Bar Digital Filter settable from 0.0 to 10.0(no dampening = 0.0)Decimal point position.(Setting is not stored in non-volatile memory)Hold UP switch for 3seconds to reset.Hold UP switch for 3 seconds to reset.Hold UP switch for 3 seconds to reset all factory defaults.Span calibrationadjustment.Multiplies reading.Range: 0.90-1.10Offset calibrationadjustment.Adds to reading.

AC/DC PoweredDigital Pressure GaugeDPG101M5702/1218DPG101 is an electronic digital pressure gauge used to monitor hydraulic fluids. It monitors thepressure via the resistance measured on an isolation membrane. T he output signal is amplified by ahigh-precision, low-temperature drift amplifier. T he signal is then fed into a high accuracy A/D converter for the microprocessor to process and then show on the LED display.This flexible, simple to operate digital pressure guage is safe, reliable, and easy to debug. T he DPG101 is widely used in hydro-power, water, petroleum, chemical, mechanical, hydraulic, and other industries.Features• High resolution, 4-digit LED display• 100mm standard gauge dial • Stainless steel structure• Parameter correction function (adjust instrument zero and error value)SpecificationsNote, if the fluid being measured exceeds 80ºC, select the high temperature accessory.•Measuring Range-0.1~0~100MPa•Accuracy Range±0.25% for gauge pressure >5psi±0.5% FS for all others including absolute, compound gauge, and Vacuum ranges •Overload Pressure 150%~200%•Pressure TypeG/A•Stability≤0.1% FS per year•Power Supply220VAC•Display4 digits0.56”LED•IP RatingIP65•Relative Humidity≤90%•Operating Temp-30ºC ~ 80ºC•Fluid Temp-40ºC ~150ºC •Thread Size1/4 NPT Male•Thread MaterialSS316DimensionsMechanical InstallationInstall directly on the hydraulic pipe line.

安装一个消过毒的（或者一次性的）专门棱镜到眼压计头上，然后将棱镜置于角膜上。
检查人员使用10倍放大的裂隙灯生物显微镜借助蓝色滤镜查看两个发荧光的绿色半圆。
然后用转盘调整施加给眼压计头的力，直到这两个半圆的内边缘对准。
由于对角膜有物理接触，因此有必要对患者角膜使用局部麻醉剂。
1.2 仪器的拟定用途/目的凯乐数字式压平眼压计适用于测量眼压，以辅助筛查和诊断青光眼。
联邦法律规定该仪器仅限于内科医生或者执业医师购买或者根据其订单销售。
凯乐数字式压平眼压计（D-KAT）是大多数“照明台”型裂隙灯的附件。
因其良好的通用性，D-KAT眼压计可装到许多制造商生产的裂隙灯或者与其共同使用。
如果该仪器以任何方式被捣弄或日常维护被忽略或不按照制造商的指导进行，制造商拒绝任何和所有责任和质量保证内容。
裂隙灯上的R型（固定式）1. 引言1.3 如何测定眼压（IOP）眼压计探测臂组件末端环形支座上的丙烯酸测量棱镜压平角膜。
棱镜是平整的，带有光滑或者圆润的边缘，以防止对角膜造成任何损伤。
通过向前移动裂隙灯，使测量棱镜与患者的眼睛接触。
这时，转动测量鼓来提高眼睛上的压力，直到形成一个连续的整块的直径3.06毫米（面积7.354平方毫米）的被压平平面。
该双像棱镜将图像分开，呈现出两个相对的3.06毫米的半圆部分（参阅7.4.2节测量程序了解更多细节）。
1.4 戈德曼（）型眼压计的优点• 在使用裂隙灯的常规检查中就可以测量眼压。
