pneumatic pressure workload.<\/p>\n<p>Depending on the installed Q-RPT configuration, the controller can operate from vacuum and very low differential pressure up to:<\/p>\n<p><strong>14 MPa<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>2,000 psi<\/strong><\/p>\n<p>which corresponds to approximately:<\/p>\n<p><strong>140 bar<\/strong><\/p>\n<p>This broad operating range enables one PPC4 platform to calibrate many different pressure instruments.<\/p>\n<p>Typical devices under test include:<\/p>\n<ul data-spread=\"false\">\n<li>Mechanical pressure gauges<\/li>\n<li>Digital pressure gauges<\/li>\n<li>Pressure sensors<\/li>\n<li>Pressure transducers<\/li>\n<li>Pressure transmitters<\/li>\n<li>Pressure switches<\/li>\n<li>Pressure modules<\/li>\n<li>Reference pressure instruments<\/li>\n<\/ul>\n<h2>Q-RPT Quartz Reference Pressure Transducers<\/h2>\n<p>The measurement performance of the <strong>Fluke Calibration PPC4<\/strong> is based on Fluke Calibration Q-RPT technology.<\/p>\n<p>Q-RPT stands for:<\/p>\n<p><strong>Quartz Reference Pressure Transducer<\/strong><\/p>\n<p>The technology provides excellent pressure measurement characteristics including:<\/p>\n<ul data-spread=\"false\">\n<li>High resolution<\/li>\n<li>Excellent repeatability<\/li>\n<li>Low hysteresis<\/li>\n<li>Good linearity<\/li>\n<li>Excellent long-term stability<\/li>\n<\/ul>\n<p>Different Q-RPT ranges can be selected according to the required pressure workload.<\/p>\n<p>Available ranges extend from very low differential pressure configurations to a maximum Q-RPT range of:<\/p>\n<p><strong>14 MPa \/ 2,000 psi<\/strong><\/p>\n<h2>Three Q-RPT Performance Classes<\/h2>\n<p>The <strong>Fluke Calibration PPC4<\/strong> offers three Q-RPT performance classes.<\/p>\n<p>These allow the pressure controller to be optimized according to measurement requirements and investment cost.<\/p>\n<p>The available classes include:<\/p>\n<p><strong>Full Scale Standard Q-RPT<\/strong><\/p>\n<p><strong>Standard Q-RPT<\/strong><\/p>\n<p><strong>Premium Q-RPT<\/strong><\/p>\n<p>This provides considerable flexibility when configuring a calibration system.<\/p>\n<h2>Premium Q-RPT Performance<\/h2>\n<p>For demanding calibration applications, the <strong>Premium Q-RPT<\/strong> provides the highest measurement performance.<\/p>\n<p>Fluke specifies precision down to:<\/p>\n<p><strong>\u00b10.005 % of reading<\/strong><\/p>\n<p>over the specified portion of an AutoRanged span.<\/p>\n<p>Measurement uncertainty can be as low as:<\/p>\n<p><strong>\u00b10.008 % of reading<\/strong><\/p>\n<p>under the specified conditions.<\/p>\n<p>This makes Premium Q-RPT configurations particularly attractive for reference laboratories and applications requiring excellent test uncertainty ratios.<\/p>\n<h2>Standard Q-RPT Performance<\/h2>\n<p>The <strong>Standard Q-RPT<\/strong> provides excellent measurement performance for a wide range of professional calibration applications.<\/p>\n<p>Fluke specifies precision of:<\/p>\n<p><strong>\u00b10.008 % of reading<\/strong><\/p>\n<p>from 30 % to 100 % of Q-RPT span.<\/p>\n<p>Measurement uncertainty is specified at:<\/p>\n<p><strong>\u00b10.010 % of reading<\/strong><\/p>\n<p>over the same portion of the range.<\/p>\n<p>Below 30 % of the Q-RPT span, corresponding span-based specifications apply.<\/p>\n<h2>Full Scale Standard Q-RPT<\/h2>\n<p>The Full Scale Standard Q-RPT provides an economical alternative for applications where percent-of-AutoRanged-span performance is appropriate.<\/p>\n<p>Precision is specified at:<\/p>\n<p><strong>\u00b10.010 % of AutoRanged span<\/strong><\/p>\n<p>Measurement uncertainty is:<\/p>\n<p><strong>\u00b10.015 % of AutoRanged span<\/strong><\/p>\n<p>The minimum AutoRanged span is generally limited according to the installed Q-RPT configuration.<\/p>\n<h2>Excellent Long-Term Stability<\/h2>\n<p>Fluke specifies predicted one-year Q-RPT measurement stability of:<\/p>\n<p><strong>\u00b10.005 % of reading<\/strong><\/p>\n<p>when AutoZero is regularly used according to the manufacturer&#8217;s specifications.<\/p>\n<p>Long-term stability is particularly important when the PPC4 is used as a reference standard in a calibration laboratory.<\/p>\n<p>Stable measurement performance helps maintain predictable measurement uncertainty between calibration intervals.<\/p>\n<h2>Pressure Control Precision to 4 ppm<\/h2>\n<p>One of the outstanding characteristics of the <strong>Fluke Calibration PPC4<\/strong> is its pressure control performance.<\/p>\n<p>Fluke specifies control precision of:<\/p>\n<p><strong>\u00b14 ppm of Q-RPT span<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>\u00b10.4 ppm of the Hi Q-RPT span<\/strong><\/p>\n<p>whichever is greater.<\/p>\n<p>The default control precision is:<\/p>\n<p><strong>\u00b10.005 % of the AutoRanged range<\/strong><\/p>\n<p>This extremely fine control capability is particularly valuable when calibrating high-resolution pressure sensors and reference pressure instruments.<\/p>\n<h2>50:1 Control Turndown<\/h2>\n<p>The PPC4 provides a pressure control turndown of up to:<\/p>\n<p><strong>50:1<\/strong><\/p>\n<p>Wide control turndown enables one controller configuration to provide excellent control performance across a broad pressure workload.<\/p>\n<p>This reduces the need to manually adjust the supply pressure when switching between devices with different pressure ranges.<\/p>\n<h2>AutoRange Function<\/h2>\n<p>The <strong>Fluke Calibration PPC4<\/strong> includes Fluke Calibration&#8217;s AutoRange functionality.<\/p>\n<p>The user enters the full-scale pressure range of the device under test.<\/p>\n<p>The PPC4 then automatically optimizes relevant parameters for that range.<\/p>\n<p>AutoRange can adjust:<\/p>\n<ul data-spread=\"false\">\n<li>Measurement range<\/li>\n<li>Pressure control<\/li>\n<li>Resolution<\/li>\n<li>Ready criteria<\/li>\n<li>Safety limits<\/li>\n<li>Calibration parameters<\/li>\n<\/ul>\n<p>This simplifies calibration when many different pressure ranges are handled by the same controller.<\/p>\n<h2>Real-Time Uncertainty Calculation<\/h2>\n<p>An important feature of the <strong>Fluke Calibration PPC4<\/strong> is real-time uncertainty calculation.<\/p>\n<p>The system can calculate the uncertainty associated with the measured and delivered pressure.<\/p>\n<p>The uncertainty information is available through both local and remote interfaces.<\/p>\n<p>This provides the operator or automated calibration software with valuable information about the active measurement configuration.<\/p>\n<p>It also helps users select an appropriate Q-RPT range for a specific device under test.<\/p>\n<h2>Dynamic Pressure Control<\/h2>\n<p>In <strong>Dynamic Mode<\/strong>, the PPC4 continuously adjusts pressure to maintain the selected setpoint.<\/p>\n<p>The controller generates the required pressure, enters the defined hold limit and continuously compensates for pressure changes.<\/p>\n<p>Pressure is indicated as ready when it is within the defined hold limit.<\/p>\n<p>This mode is particularly useful when continuous active pressure regulation is required.<\/p>\n<h2>Static Pressure Control<\/h2>\n<p>The <strong>Fluke Calibration PPC4<\/strong> also provides Static Mode.<\/p>\n<p>In Static Mode, the controller generates pressure until the target is within the defined hold limit.<\/p>\n<p>Active pressure control is then stopped in the closed test volume.<\/p>\n<p>The system evaluates pressure stability according to the selected stability criteria.<\/p>\n<p>Static control can be advantageous for high-accuracy measurements where continuous control activity is undesirable.<\/p>\n<h2>Fast Pressure Control<\/h2>\n<p>The PPC4 combines high measurement performance with fast automatic pressure generation.<\/p>\n<p>For the manufacturer&#8217;s specified test conditions with a 50 cc test volume and a 0.005 % hold limit, typical pressure setting ready times are approximately:<\/p>\n<p><strong>15 to 35 seconds<\/strong><\/p>\n<p>The typical slew time from atmospheric pressure to full scale with a 50 cc test volume is approximately:<\/p>\n<p><strong>30 seconds<\/strong><\/p>\n<p>Actual pressure stabilization depends on the selected Q-RPT, pressure range, test volume, tubing, temperature and device under test.<\/p>\n<h2>Gauge, Absolute and Bidirectional Gauge Pressure<\/h2>\n<p>The <strong>Fluke Calibration PPC4<\/strong> provides excellent flexibility for different pressure modes.<\/p>\n<p>The system supports:<\/p>\n<ul data-spread=\"false\">\n<li>Gauge pressure<\/li>\n<li>Absolute pressure<\/li>\n<li>Negative gauge pressure<\/li>\n<li>Bidirectional gauge pressure<\/li>\n<\/ul>\n<p>Suitable configurations allow instantaneous switching between absolute, gauge and bidirectional gauge modes without additional hardware or separate calibration requirements.<\/p>\n<p>This flexibility enables a single PPC4 system to cover a broad range of pressure calibration tasks.<\/p>\n<h2>Low Absolute Pressure Capability<\/h2>\n<p>With a suitable vacuum system, the PPC4 can operate at very low absolute pressures.<\/p>\n<p>With the low ultimate pressure option and appropriate vacuum equipment, typical ultimate pressure can reach approximately:<\/p>\n<p><strong>50 Pa<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>0.5 mbar<\/strong><\/p>\n<p>Without the low ultimate pressure option, typical ultimate pressure is approximately:<\/p>\n<p><strong>200 to 700 Pa<\/strong><\/p>\n<p>depending on the vacuum pump and pressure connections.<\/p>\n<p>This enables the PPC4 to cover pressure applications extending well below atmospheric pressure.<\/p>\n<h2>Automatic AutoZero<\/h2>\n<p>The <strong>Fluke Calibration PPC4<\/strong> provides automated AutoZero functionality.<\/p>\n<p>In gauge pressure mode, AutoZero occurs automatically when the system is vented.<\/p>\n<p>In absolute pressure mode, the internal barometric reference can be used for AutoZero.<\/p>\n<p>Regular AutoZero operation supports the excellent long-term stability of the Q-RPT reference measurement system.<\/p>\n<h2>Automatic Pressure Head Correction<\/h2>\n<p>Differences in vertical height between the reference pressure sensor and the device under test can produce measurable pressure differences.<\/p>\n<p>The PPC4 therefore provides automatic pressure head correction.<\/p>\n<p>The correction can compensate for the vertical distance between the pressure reference level and the DUT reference level.<\/p>\n<p>This is especially important when working with low pressures and demanding measurement uncertainties.<\/p>\n<h2>Automatic Leak Testing<\/h2>\n<p>The <strong>Fluke Calibration PPC4<\/strong> includes automated leak testing routines.<\/p>\n<p>Leak testing helps identify problems in:<\/p>\n<ul data-spread=\"false\">\n<li>Pressure tubing<\/li>\n<li>Fittings<\/li>\n<li>Adapters<\/li>\n<li>Test manifolds<\/li>\n<li>Devices under test<\/li>\n<\/ul>\n<p>A leak-tight system is important for both pressure stability and calibration efficiency.<\/p>\n<p>Automated leak testing simplifies verification before demanding calibration procedures.<\/p>\n<h2>Programmable Calibration Sequences<\/h2>\n<p>Calibration sequences can be programmed directly into the PPC4.<\/p>\n<p>This allows repetitive calibration procedures to be automated.<\/p>\n<p>The controller can execute predefined pressure points and evaluate the connected unit under test.<\/p>\n<p>On-board UUT tolerance testing further supports routine calibration workflows.<\/p>\n<p>These functions can reduce operator workload and improve consistency between calibrations.<\/p>\n<h2>Clean Gas Pressure Medium<\/h2>\n<p>The <strong>Fluke Calibration PPC4<\/strong> operates with:<\/p>\n<p><strong>any clean, dry, non-corrosive gas<\/strong><\/p>\n<p>This pneumatic operating principle helps keep connected pressure instruments free from hydraulic oil contamination.<\/p>\n<p>Clean gas operation is particularly useful for:<\/p>\n<ul data-spread=\"false\">\n<li>Pneumatic pressure sensors<\/li>\n<li>Gas pressure systems<\/li>\n<li>Aerospace instrumentation<\/li>\n<li>Reference pressure instruments<\/li>\n<li>Production sensors<\/li>\n<li>Research equipment<\/li>\n<\/ul>\n<h2>Self-Purging Liquid Trap<\/h2>\n<p>Devices under test may contain residual oil, water or other liquids.<\/p>\n<p>These contaminants should not enter the precision pressure controller.<\/p>\n<p>Fluke therefore offers the optional:<\/p>\n<p><strong>SPLT \u2013 Self-Purging Liquid Trap<\/strong><\/p>\n<p>The SPLT is installed at the PPC4 test port and helps protect the pressure controller from liquid contamination.<\/p>\n<p>This accessory is particularly useful for calibration laboratories handling devices from different industrial applications.<\/p>\n<h2>Calibration of Pressure Sensors<\/h2>\n<p>The <strong>Fluke Calibration PPC4<\/strong> is ideal for automatic pressure sensor calibration.<\/p>\n<p>The controller generates and measures the required pressure while suitable electrical equipment measures the sensor output.<\/p>\n<p>Typical characteristics that can be evaluated include:<\/p>\n<ul data-spread=\"false\">\n<li>Zero<\/li>\n<li>Span<\/li>\n<li>Linearity<\/li>\n<li>Repeatability<\/li>\n<li>Hysteresis<\/li>\n<li>Pressure sensitivity<\/li>\n<\/ul>\n<p>Automatic pressure generation makes repetitive multipoint calibration significantly more efficient.<\/p>\n<h2>Calibration of Pressure Transmitters<\/h2>\n<p>The PPC4 can serve as the pressure generation and reference system for pressure transmitter calibration.<\/p>\n<p>The PPC4 provides the reference pressure while an electrical calibrator or digital multimeter measures the transmitter output.<\/p>\n<p>Typical output signals include:<\/p>\n<ul data-spread=\"false\">\n<li>4\u201320 mA<\/li>\n<li>DC voltage<\/li>\n<li>Digital communication signals<\/li>\n<\/ul>\n<p>Automated pressure control is especially useful when many increasing and decreasing calibration points are required.<\/p>\n<h2>Pressure Gauge Calibration<\/h2>\n<p>Mechanical and digital pressure gauges can also be calibrated automatically using the <strong>Fluke Calibration PPC4<\/strong>.<\/p>\n<p>A typical sequence consists of several increasing and decreasing pressure points.<\/p>\n<p>The indication of the device under test is compared with the Q-RPT reference value.<\/p>\n<p>Depending on the calibration procedure, this allows evaluation of:<\/p>\n<ul data-spread=\"false\">\n<li>Indication deviation<\/li>\n<li>Repeatability<\/li>\n<li>Hysteresis<\/li>\n<li>Zero deviation<\/li>\n<\/ul>\n<h2>External Q-RPT via RPM4<\/h2>\n<p>The PPC4 supports external Q-RPT reference pressure transducers installed in an:<\/p>\n<p><strong>RPM4 Reference Pressure Monitor<\/strong><\/p>\n<p>This provides several advantages.<\/p>\n<p>The external reference can be positioned closer to the device under test.<\/p>\n<p>It can also be removed separately for calibration without removing the complete PPC4 controller from the calibration system.<\/p>\n<p>This is particularly valuable in automated systems where minimizing downtime is important.<\/p>\n<h2>User Interfaces<\/h2>\n<p>The <strong>Fluke Calibration PPC4<\/strong> is available with different user interface configurations.<\/p>\n<p>The <strong>PPC4-ui<\/strong> provides an advanced user interface featuring:<\/p>\n<ul data-spread=\"false\">\n<li>Color display<\/li>\n<li>Full keypad<\/li>\n<li>Point-and-click control knob<\/li>\n<li>Multilingual operation<\/li>\n<\/ul>\n<p>The advanced user interface supports eleven languages.<\/p>\n<p>A basic PPC4 version is also available with a simpler display and keypad arrangement.<\/p>\n<p>This allows users to select the interface according to their application and budget.<\/p>\n<h2>Communication Interfaces<\/h2>\n<p>The PPC4 provides extensive remote communication capability.<\/p>\n<p>Standard interfaces include:<\/p>\n<ul data-spread=\"false\">\n<li>RS-232<\/li>\n<li>Front-panel USB<\/li>\n<\/ul>\n<p>Depending on the configuration, optional interfaces include:<\/p>\n<ul data-spread=\"false\">\n<li>IEEE-488.2<\/li>\n<li>Ethernet<\/li>\n<li>Rear-panel USB<\/li>\n<\/ul>\n<p>These interfaces allow the PPC4 to be
