For best performance, Hastings vacuum gauges should be operated with the appropriate Hastings gauge tube. Attempting to use a Hastings vacuum gauge with other manufacturer’s tubes may result in damage to both the gauge and tube.1.1. FeaturesHastings vacuum gauges and controllers are self-contained instruments that offer extreme versatility for most vacuum applications. The electronic design assures long life and minimal maintenance. Compact VT & CVT Models are ready for mounting onto a panel.Hastings vacuum gauges and controllers utilize Hastings rugged but sensitive gauge tubes which are designed specifically for each of the three available pressure ranges (consult Hastings Ordering and Dimension guide).1.2.

SafetyThe following symbols and terms may be found on THI products and/or in THI manuals and indicateimportant information.When found on the device, this symbol indicates that the operator should refer to the manual for important instructions on the proper use of this device. When found in a manual, this symbol indicates that the reader should understand the implications contained in the text before operating the device.The WARNING label indicates important information that should be heeded for safe and proper performance of the device.1.0The label, CAUTION, is used to indicate that damage to the power supply or equipment connected to it, could occur if directions are not followed. Warranty could be invalidated if the instructions in this manual are not followed.1.4. AccessoriesTHI offers a complete line of system attachments that permit easy maintenance for contaminated operations.Gauge tubes are offered with various system fittings tomatch almost any system requirement. Additionally, THI’s complete line of quick disconnect attachments allows customers to install these special fittings and easily replacesensors without vacuum sealant or Teflon® tape. For particularly dirty systems, Hastings offers a particle dropout trap containing a series of nine separate baffles which prevent solid contaminants from having a direct path tothe sensor’s thermopile.1.5. DV-6S: New DV-6 tube ForSevere EnvironmentsHastings Instruments has developed a new gauge tube, the DV-6S, which is specifically designed for outdoor use on cryogenic tanks including railcar and tanker truckapplications. In addition to the DAVC, the gauge tube is compatible with the hand-held HPM-4/6 and the analog VT-6. The DV-6S is supplied with a protective cap. The o-ring-sealed cap protects the gauge tube pins from moisture thussignificantly reducing corrosion. A metal lanyard prevents cap loss. The tube isprovided with a standard 1/8” NPT fitting; however special fitting requests can often be met.1.6. Calibration Reference TubesTHI Reference Tubes employ the samemetal thermopiles used in all THI Vacuum Gauge Tubes. The thermopile is sealed in a glass capsule that has been evacuated, baked, out-gassed, and then aged to ensure long-term stability. The sealed capsule is then housed in a protective metal shell to provide a rugged, trouble-free assembly.Once assembled, the reference gauge tube is accurately calibrated to precisely simulate a gauge tube at agiven operating pressure. It provides quick and easy instrument re-calibration by merely plugging the instrument and adjusting the calibration potentiometer until the display reads the exact pressure noted on the reference tube.Extension Cables for VT Series55-3 OM-8-OFV 8 Ft Extension Cable 55-22 OM-12-OFV 12 Ft Extension Cable65-53 OM-25-OFV 25 Ft Extension Cable 65-102 OM-50-OFV 50 Ft Extension Cable 55-142 OM-100-OFV 100 Ft Extension CableVacuum Gauge Tubes 1000 mTorr Range Stock # Model # Description 55-38 DV-6M 1/8” NPT Standard (Yellow base)55-38R DV-6R 1/8” Ruggedized 55-38RSDV-61/8” NPT Rohs Rugged55-38S DV-6S 1/8” NPT Rugged/Vibration 55-251 DV-6-KF-16 KF-16TM 55-267 DV-6-KF-25 KF-25TM55-283 DV-6-VCR VCR TM55-38R-CF DV-6R-CF Mini Conflat TMVacuum Gauge Tubes 100 mTorr Range55-19 DV-5M 1/8” NPT (Red Base) 55-230DV-5M -VCRVCR TMVacuum Gauge Tubes 20Torr Range55-19DV-4D1/8” NPT (Purple Base)55-19R DV-4R 1/8” NPT Ruggedized 55-258 DV-4D-KF-16 KF-16TM 55-266 DV-4D-KF-25 KF-25TM55-227 DV-4D-VCR VCR TMReference Tubes for use with VT/CVT55-104 DB-20 Ref Tube (DV-6) for DV-6 Calibration 55-101 DB-16D Ref Tube (DV-4D) for DV-4 Calibration 55-103DB-18Ref Tube (DV-5) for DV-5 Calibration2.02.2. Cabinet Mount Vacuum GaugeHastings cabinet models can be obtained with 2 - position or 5 - position tube switching functions that will allow the user to display pressure from one or more selected tubes. No special installation is necessary; simply connect the power cord and the gauge tube cables.Note: All of the gauge tube cables on either a 2-position or a 5-position unit must be equal in length. Mixing cable lengths on a particular unit will produce a calibration error due to the different resistances of the cables.2.3. External Cables and WiringWARNING: To prevent shock hazard to personnel, always install protective cover before application of AC power or prior to placing instrument in-service.VT series unitsConnect the AC power cable, gauge tube cable, and analog output (analog output is only available on units configured from the factory with 0-1 VDC) as detailed in figure 2-4. The terminal block protective cover must be removed to access screw terminals. Terminal FunctionDescription3 Gauge tube cable Heated T.C.

Once the protective cap or cover is removed, a tube can be installed in any convenient position in the vacuum system without adversely affecting calibration or performance. The recommended orientation is with the tube vertical and its stem down. This will aide in preventing condensable materials from remaining in the gauge tube.Hastings instruments also offer a wide variety of installation accessories for use with your vacuum gauge tube. Please consult the Hastings Ordering and Dimension Guide or contact your factory representative for information on these products.WARNING: Compression seal fittings “Quick-Connects” are not for use insystems where the tube can be pressurized above atmosphere.3.1. Meter Mechanical ZeroWith the gauge in its normal operating position (AC power removed), check that the meter pointer covers the Dot at right-end of the dial face. If the Dot is not covered by the pointer, adjust screw at the front of the meter until the pointer covers the Dot.3.2. AC Input PowerConnect the plug end of power cable into a single phase 115 or 230 V, 50/60 Hz power source (as per unit configuration). When replacing the power cords standard plug with a plug to match a particular system, care should be taken to connect the new plug in accordance with the terminal block connections listed in section 2.4 of this manual.3.3. Pressure MeasurementConnect gauge tube cables octal socket onto the octal base of a gauge tube installed in vacuum system. The gauge will display the system pressure on the meter dial face. To check the accuracy of the gauge, perform the required operations as specified in section 3.5 of this manual.3.4. Controller Set Points (CVT units only)The CVT series vacuum controllers are provided with either single or double set points. On a single set point controller, the right-front panel knob allows the user to adjust or position the “RED” pointer on the dial face where a desired control function will occur.On the double set point controller, the left-front panel knob is added to allow the user to adjust or position a second “RED” pointer on the dial face where a desired control function will occur.On those controllers configured with two front panel knobs; the left knob controls the LO Set pressure (Relay K1), and the right knob controls the HI Set pressure (Relay K2). Control logic determines that a relay will (energize) when the indicated pressure is lower than the set-pressure, and de-energize when the indicated pressure is higher than the set-pressure or if their is a loss of AC power to the unit.3.5. Operation and Performance CheckAll Hastings vacuum gauges, controllers, and tubes have been carefully calibrated and checked at the factory before shipment. When a operational check or calibration is desired, refer to the procedure outlined in this section.The simplest and quickest way of checking the operation and performance of a gauge and/or gauge tube is to maintain a new or known-good gauge tube on hand for use as a Reference. To check operation, install both the Reference and suspect gauge tubes in a common vacuum3.0 To avoid relay chatter, keep the lower set point above the ultimate system pressureCAUTION:system (locate the gauge tubes as close as possible to each other), then evacuate the system until a stable base pressure is obtained. Alternately connect the vacuum gauge to each gauge tube and record its pressure readings. If the gauge tube-under-test produces a higher pressure reading than the Reference gauge tube, this indicates a calibration shift and is usually the result of contamination (particulate, oil, or other chemical deposits). You can try to restorecalibration of the contaminated gauge tube by cleaning it internally with an appropriate solvent such as high-purity isopropyl alcohol (flood interior cavity of gauge tube gently with solvent and allow it to stand and soak for about 15 to 30-minutes). Drain the contaminated solvent and let gauge tube dry in ambient air until all of the cleaning solvent has evaporated. Toprevent mechanical damage to the thermopile elements, do not use forced air to dry the gauge tube. Gauge tubes that remain out of3.6. Gauge Tube OperationOperation of the Hastings gauge tube isin the gauge tube changes the molecularcollision rate and therefore the thermalconduction of the gas or gas mixturetemperature shift in the AC heatedthermocouples A and B (Fig. 3.1). Thethe DC output from couples A and B3.7. Analog Pressure MeasurementAn analog Signal Output line, pin 8, supplies a 0 to 1 VDC signal corresponding to the output range of the selected tube. This signal should be measured with respect to the analog Signal Common line, pin 7. See the INSTALLATION section for a diagram showing the Analog Signal pin out.This signal is equal to an amplified tube millivolt signal. This signal will NOT be linearly proportional to the indicated pressure. 1 volt will correspond to a system pressure that is at least 1 order of magnitude less than the minimum detectable pressure. Increasing pressure will be indicated by adecreasing voltage. The minimum detectable pressure is 0.2 millitorr for DV-5, 1 millitorr for DV-6 and 20 millitorr for DV-4.The voltage signal can be mapped to a pressure value by using the following equation.Where:V = VoltageP = pressure in Torr for DV4 & DV5 versions and millitorr for DV6 See Chart below221dV bV eV cV a P ++++=Parameters DV6DV4DV5a -1623.22-5.10184-0.25948b -58.0442-6.91233-42.23869c -11732.2-4.4943-2.92598d -130.397-6.30995-256.9951e 13338.179.563177 3.180163.8.CalibrationUsing a vacuum system to calibrate a gauge or gauge/tube combination will result in a more accurate pressure measurement. For instances where this is not possible, calibrating the gauge using a Hastings reference tube provides the best alternative.NOTE: For cabinet models, the top-cover must be removed to access the CAL control.3.8.1.Calibration Using A Vacuum SystemInstall the gauge tube in a vacuum system (gauge connected to AC power and stabilized), then evacuate to a pressure one decade or more below the gauge dial face resolution. Connect the gauge to tube and wait until the displayed pressure is stable.NOTE: When using a DV-4 type gauge tube, system pressure must be less than 1.0 x10-2 Torr.When using DV-5 or DV-6 type gauge tubes, system pressure must be less than 1.0 x 10-5 Torr.Adjust the gauge CAL. adjustment (figure 3.2) until the meter pointer indicates zero-left on the dial face.3.8.2.Calibration Using A Hastings Reference TubeConnect a Hastings reference tube to a stabilized vacuum gauge. Wait until the displayed pressure is stable.NOTE: The following table specifies the Hastings reference tube to be used in the calibration of a gauge based upon the type of gauge tube being used:Reference tube Gauge tubeDB-16D DV-4DB-18 DV-5DB-20 DV-6Adjust the gauge CAL control (figure 3.2) until the meter pointer indicates the pressure specified on the decal of the reference tube in use.Fig 3.2calibration points4.04.1.Warranty Repair PolicyHastings Instruments warrants this product for a period of one year from the date of shipment to be free from defects in material and workmanship.

真空计使用方法带参数要求说明
真空计使用方法带参数要求说明真空计是一种用于测量气体压力的仪器，广泛应用于科学研究、工业生产和实验室实践中。
本文将详细介绍真空计的使用方法，并说明其相关参数要求。
一、真空计的基本原理和种类真空计的基本原理是利用气体分子与传感器间的碰撞来测量气体压力。
根据不同的原理和测量范围，真空计可以分为多种类型，如电离真空计、热导真空计、毛细管真空计、扩散真空计等。
二、真空计的使用方法1.准备工作在使用真空计之前，需要进行一些准备工作：-清洁传感器：使用温和的洗涤剂和干净的布或棉签轻轻擦拭传感器表面，确保其光洁无尘。
-检查连接管路：确保所有连接管路的接口密封良好，避免气体泄漏。
-检查真空计仪器：确认仪器的电源、指示器和控制面板正常工作。
2.接通电源将真空计连接到电源，并打开电源开关，等待仪器进行自检和初始化。
根据具体型号，可能需要设置相关参数，如量程、单位等。
3.设置测量范围根据实际需求，设置真空计的测量范围。
对于不同的真空计类型，其测量范围可能有所不同，一般可调节量程旋钮或通过仪器控制面板进行设定。
4.进行标定（可选）如果需要更高的测量精度和准确性，可以进行标定过程。
标定过程可参考真空计的用户手册，常见的标定方法包括手动标定和自动标定，根据仪器的指示进行相应操作。
5.进行测量将真空计的传感器插入待测气体环境中，确保传感器完全暴露在气体中。
一般情况下，真空计会自动读取并显示气体压力值。
如需连续测量，可设定仪器的采样频率和测量间隔。
6.结束测量和关闭真空计当测量完成后，可在仪器上停止测量或选择保存测量数据。
然后，关闭真空计的电源开关，断开与气体环境的连接。
三、真空计使用时的参数要求1.真空计的精度和准确度要求根据实际应用而定，一般会标明在特定范围内的测量误差。
2.真空计的量程需根据实际测量范围来设定，并需保证测量数据在该范围内具有足够的准确性和可靠性。
3.真空计的响应时间要求取决于具体应用场景，一般要能够满足实时或近实时的测量需求，避免延迟和漏测。
