Calibrator<\/h2>\n<p>The <strong>Additel ADT223A<\/strong> was developed as a highly integrated calibration platform for process instrumentation.<\/p>\n<p>Instead of requiring separate instruments for pressure, temperature, electrical signals and HART communication, the ADT223A combines these functions in one handheld calibrator.<\/p>\n<p>Typical applications include calibration and testing of:<\/p>\n<ul>\n<li>Pressure transmitters<\/li>\n<li>Temperature transmitters<\/li>\n<li>HART transmitters<\/li>\n<li>RTD instruments<\/li>\n<li>Thermocouple instruments<\/li>\n<li>Process indicators<\/li>\n<li>Pressure switches<\/li>\n<li>Temperature switches<\/li>\n<li>Controllers<\/li>\n<li>PLC inputs<\/li>\n<li>Flow totalizers<\/li>\n<li>Data acquisition systems<\/li>\n<\/ul>\n<p>This broad functionality makes the ADT223A particularly useful for calibration laboratories, process industries, maintenance departments and field service applications.<\/p>\n<h2>Integrated HART Communication<\/h2>\n<p>One of the most important features of the <strong>Additel ADT223A<\/strong> is its HART communication capability.<\/p>\n<p>HART combines a conventional analog 4\u201320 mA process signal with digital communication.<\/p>\n<p>This technology is widely used in intelligent process transmitters because it allows additional device information and configuration data to be communicated without eliminating the traditional analog current signal.<\/p>\n<p>The ADT223A supports HART instrumentation and is designed for calibration, maintenance and troubleshooting of compatible HART devices.<\/p>\n<p>This differentiates the ADT223A from the ADT221A and ADT222A within the original 22XA product family.<\/p>\n<h2>Pressure Measurement with Intelligent Modules<\/h2>\n<p>The <strong>Additel ADT223A<\/strong> supports compatible Additel intelligent digital pressure modules.<\/p>\n<p>The ADT160A pressure module family specified for the ADT222A and ADT223A provides pressure ranges extending approximately from:<\/p>\n<p><strong>-15 psi to 10,000 psi<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>-1 bar to 700 bar<\/strong>.<\/p>\n<p>Different pressure modules can be selected according to the required measurement range and application.<\/p>\n<p>This modular approach allows the ADT223A to cover several pressure ranges without integrating a fixed pressure sensor into the calibrator itself.<\/p>\n<h2>Intelligent Pressure Module Concept<\/h2>\n<p>Calibration characteristics are stored in the compatible pressure module.<\/p>\n<p>When a module is connected, the ADT223A recognizes it and integrates pressure into the available calibration functions.<\/p>\n<p>This offers several practical advantages.<\/p>\n<p>A user can select a module with a suitable pressure range and accuracy for the application and change modules when a different range is required.<\/p>\n<p>This makes the ADT223A a flexible platform for calibration laboratories with a broad pressure workload.<\/p>\n<h2>RTD Measurement and Simulation<\/h2>\n<p>The <strong>Additel ADT223A<\/strong> supports measurement and simulation of <strong>11 RTD types<\/strong>.<\/p>\n<p>Supported sensor characteristics include commonly used platinum resistance thermometers such as:<\/p>\n<ul>\n<li>Pt100 (385)<\/li>\n<li>Pt100 (3916)<\/li>\n<li>Pt100 (3926)<\/li>\n<li>Pt500 (385)<\/li>\n<li>Pt1000 (385)<\/li>\n<\/ul>\n<p>as well as additional resistance thermometer characteristics.<\/p>\n<p>For the commonly used Pt100 (385), the supported temperature range extends from:<\/p>\n<p><strong>-200 \u00b0C to 850 \u00b0C<\/strong>.<\/p>\n<p>The ADT223A can measure an actual resistance thermometer or simulate its electrical resistance to test a transmitter, indicator, controller or PLC input.<\/p>\n<h2>Precise Pt100 Calibration<\/h2>\n<p>The <strong>Additel ADT223A<\/strong> provides high-performance RTD measurement and simulation for electrical temperature calibration.<\/p>\n<p>For a Pt100 (385), Additel specifies measurement accuracy down to approximately:<\/p>\n<p><strong>0.10 \u00b0C<\/strong><\/p>\n<p>in 4-wire configuration over the -200 \u00b0C to 200 \u00b0C range.<\/p>\n<p>The ability to measure and simulate RTDs makes the ADT223A suitable for checking both sides of an electrical temperature measurement chain.<\/p>\n<p>For example, a technician can measure a Pt100 sensor or simulate a Pt100 to verify the connected transmitter.<\/p>\n<h2>Thermocouple Measurement and Simulation<\/h2>\n<p>The Additel ADT223A supports <strong>13 thermocouple types<\/strong>.<\/p>\n<p>The calibrator can both measure thermocouple signals and generate the millivolt signals corresponding to defined temperatures.<\/p>\n<p>Typical applications include calibration of:<\/p>\n<ul>\n<li>Thermocouple transmitters<\/li>\n<li>Temperature indicators<\/li>\n<li>Process controllers<\/li>\n<li>PLC temperature inputs<\/li>\n<li>Data acquisition systems<\/li>\n<li>Temperature recorders<\/li>\n<\/ul>\n<p>Electrical simulation eliminates the need to generate an actual physical temperature when only the electronic measurement chain needs to be tested.<\/p>\n<h2>Calibrated Cold Junction Compensation<\/h2>\n<p>Accurate cold junction compensation is essential for thermocouple measurement and simulation.<\/p>\n<p>The <strong>Additel ADT223A<\/strong> uses a cold junction equalizing block containing a calibrated PRT element.<\/p>\n<p>An important feature of this design is that the PRT element can be removed from the calibrator.<\/p>\n<p>It can therefore be recalibrated and corrected at the ice point.<\/p>\n<p>This provides an important metrological advantage for laboratories that want greater control over the cold junction compensation contribution to their thermocouple calibration uncertainty.<\/p>\n<h2>Built-In Temperature Readout<\/h2>\n<p>The ADT223A also provides a built-in temperature readout function.<\/p>\n<p>Coefficients of a calibrated PRT can be entered into the calibrator for accurate temperature measurement.<\/p>\n<p>This allows the ADT223A to be used with a suitable calibrated resistance thermometer for direct temperature measurement applications.<\/p>\n<p>The feature expands the instrument beyond simple RTD simulation and supports more demanding temperature calibration workflows.<\/p>\n<h2>Electrical Measurement and Source Functions<\/h2>\n<p>The <strong>Additel ADT223A<\/strong> provides comprehensive electrical measurement and generation functions.<\/p>\n<p>The platform supports:<\/p>\n<ul>\n<li>mV<\/li>\n<li>V<\/li>\n<li>mA<\/li>\n<li>Resistance<\/li>\n<li>Frequency<\/li>\n<li>Pulse<\/li>\n<li>RTDs<\/li>\n<li>Thermocouples<\/li>\n<\/ul>\n<p>These functions allow technicians to test several parts of a process measurement chain using one instrument.<\/p>\n<p>For example, the calibrator can simulate a sensor input while also supporting evaluation of the electrical output of a transmitter.<\/p>\n<h2>4\u201320 mA Process Calibration<\/h2>\n<p>The ADT223A is well suited for working with standard <strong>4\u201320 mA process signals<\/strong>.<\/p>\n<p>In a typical process transmitter:<\/p>\n<p><strong>4 mA represents 0%<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>20 mA represents 100%<\/strong><\/p>\n<p>of the configured measurement range.<\/p>\n<p>The ADT223A can measure and generate electrical process signals and, combined with its HART capability, work with both the analog and digital aspects of compatible smart transmitters.<\/p>\n<p>This is particularly valuable for calibration and troubleshooting of modern process instrumentation.<\/p>\n<h2>24 V Loop Power<\/h2>\n<p>The <strong>Additel ADT223A<\/strong> includes an integrated:<\/p>\n<p><strong>24 V loop power supply<\/strong>.<\/p>\n<p>This allows suitable two-wire process transmitters to be powered directly from the calibrator.<\/p>\n<p>A separate external loop power supply is therefore unnecessary for many routine transmitter calibration applications.<\/p>\n<p>This simplifies the test setup, particularly during mobile field calibration.<\/p>\n<h2>Simultaneous Dual Readings<\/h2>\n<p>The ADT223A provides simultaneous dual reading capability.<\/p>\n<p>This allows two relevant parameters to be monitored during a calibration task.<\/p>\n<p>For transmitter calibration, this can be especially useful because an applied input and an electrical output often need to be evaluated at the same time.<\/p>\n<p>Combining both readings on one instrument simplifies the calibration workflow.<\/p>\n<h2>Automatic Switch Test<\/h2>\n<p>The <strong>Additel ADT223A<\/strong> provides automatic switch testing.<\/p>\n<p>Typical applications include:<\/p>\n<ul>\n<li>Pressure switches<\/li>\n<li>Temperature switches<\/li>\n<li>Limit switches<\/li>\n<li>Process alarm contacts<\/li>\n<\/ul>\n<p>When used with an appropriate pressure module, the ADT223A can be used to determine the switching behavior of a pressure switch.<\/p>\n<p>Temperature and electrical switch applications can also be evaluated using the corresponding source and measurement functions.<\/p>\n<h2>Frequency and Pulse Calibration<\/h2>\n<p>Frequency and pulse measurement and generation further extend the capabilities of the ADT223A.<\/p>\n<p>Additel also specifies pulse frequency output for calibration of:<\/p>\n<p><strong>flow totalizers<\/strong>.<\/p>\n<p>This makes the calibrator useful for process calibration departments that work with pressure, temperature, electrical and frequency-based instrumentation.<\/p>\n<h2>Documenting Calibration Capability<\/h2>\n<p>The <strong>Additel ADT223A<\/strong> goes beyond conventional source and measurement functions by incorporating calibration documentation.<\/p>\n<p>Information about the device under test can be managed directly on the instrument.<\/p>\n<p>Users can create automated calibration procedures, execute tests and allow the ADT223A to calculate errors.<\/p>\n<p>Results can be displayed or stored in the internal memory.<\/p>\n<p>Out-of-tolerance points are highlighted, helping the technician identify instruments that require adjustment or further investigation.<\/p>\n<h2>As-Found and As-Left Documentation<\/h2>\n<p>The ADT223A supports:<\/p>\n<p><strong>As-found<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>As-left<\/strong><\/p>\n<p>calibration results.<\/p>\n<p>As-found data documents the condition of the device before adjustment or repair.<\/p>\n<p>As-left data documents the condition after calibration, adjustment or service.<\/p>\n<p>This provides important information for quality assurance and calibration management.<\/p>\n<p>It also allows users to determine whether an instrument was outside tolerance before adjustment.<\/p>\n<h2>Automated Calibration Procedures<\/h2>\n<p>Automated calibration procedures can reduce repetitive manual work.<\/p>\n<p>The <strong>Additel ADT223A<\/strong> allows calibration tasks to be configured and then executed according to a predefined procedure.<\/p>\n<p>The calibrator can:<\/p>\n<ul>\n<li>Perform test sequences<\/li>\n<li>Calculate errors<\/li>\n<li>Display results<\/li>\n<li>Store results<\/li>\n<li>Highlight out-of-tolerance points<\/li>\n<\/ul>\n<p>This can improve repeatability and efficiency when similar instruments are calibrated regularly.<\/p>\n<h2>Snapshot Function<\/h2>\n<p>The ADT223A includes snapshot functionality.<\/p>\n<p>Snapshots allow the operator to capture and save data during calibration or troubleshooting.<\/p>\n<p>This can be useful when a specific operating condition or instrument response needs to be documented quickly without creating a complete automated calibration task.<\/p>\n<h2>Multilingual User Interface<\/h2>\n<p>The <strong>Additel ADT223A<\/strong> provides a multilingual interface.<\/p>\n<p>Additel lists languages including:<\/p>\n<ul>\n<li>English<\/li>\n<li>German<\/li>\n<li>French<\/li>\n<li>Italian<\/li>\n<li>Spanish<\/li>\n<li>Portuguese<\/li>\n<li>Simplified Chinese<\/li>\n<\/ul>\n<p>with additional languages available depending on configuration.<\/p>\n<p>For internationally operating companies and calibration laboratories, multilingual operation can simplify training and standardization.<\/p>\n<h2>Built-In Unit Conversion<\/h2>\n<p>The ADT223A also provides built-in conversion tools.<\/p>\n<p>These include conversion of:<\/p>\n<ul>\n<li>Pressure units<\/li>\n<li>Temperature units<\/li>\n<li>Temperature and RTD resistance<\/li>\n<li>Temperature and thermocouple millivolt values<\/li>\n<\/ul>\n<p>This provides technicians with useful calculation tools directly on the calibrator.<\/p>\n<h2>Compact Handheld Design<\/h2>\n<p>Despite its extensive functionality, the <strong>Additel ADT223A<\/strong> is compact.<\/p>\n<p>Its dimensions are approximately:<\/p>\n<p><strong>100 \u00d7 192 \u00d7 52 mm<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>3.9 \u00d7 7.6 \u00d7 2.0 inches<\/strong>.<\/p>\n<p>The weight is approximately:<\/p>\n<p><strong>0.7 kg \/ 1.6 lb<\/strong>.<\/p>\n<p>The calibrator is designed for one-handed operation, making it suitable for both laboratory and field calibration.<\/p>\n<h2>3.5-Inch Color Display<\/h2>\n<p>The ADT223A uses a:<\/p>\n<p><strong>3.5-inch TFT color display<\/strong>.<\/p>\n<p>Combined with the smartphone-like menu structure, the display provides access to the instrument&#8217;s measurement, source, HART and documenting functions.<\/p>\n<p>This interface concept is designed to simplify operation despite the large number of available calibration functions.<\/p>\n<h2>Rechargeable Battery<\/h2>\n<p>The <strong>Additel ADT223A<\/strong> uses a replaceable rechargeable Li-ion battery.<\/p>\n<p>Additel specifies up to approximately:<\/p>\n<p><strong>15 hours of uninterrupted operation<\/strong><\/p>\n<p>under suitable operating conditions.<\/p>\n<p>Battery life is reduced when the 24 V loop supply is used.<\/p>\n<p>The rechargeable and replaceable battery concept supports mobile field use and long-term professional operation.<\/p>\n<h2>Misuse Protection<\/h2>\n<p>The ADT223A incorporates protection against common connection errors.<\/p>\n<p>Additel states that applying up to <strong>30 V between any two sockets<\/strong> or up to <strong>1 A to the current sockets<\/strong> will not damage the calibrator under the specified conditions.<\/p>\n<p>Once the incorrect voltage or current is removed, the calibrator returns to normal operation.<\/p>\n<p>This protection is particularly valuable during field service and troubleshooting.<\/p>\n<h2>Additel ADT223A Compared with ADT222A<\/h2>\n<p>The <strong>Additel ADT222A<\/strong> and ADT223A share pressure, temperature and electrical calibration capabilities.<\/p>\n<p>Both models support compatible pressure modules and provide RTD, thermocouple and electrical measurement and source functions.<\/p>\n<p>The key additional capability of the:<\/p>\n<p><strong>Additel ADT223A is HART communication<\/strong>.<\/p>\n<p>This makes the ADT223A particularly suitable for users who need to calibrate and troubleshoot intelligent HART process instrumentation.<\/p>\n<p>If HART communication is not required, the ADT222A provides many of the same fundamental process calibration functions.<\/p>\n<h2>Successor to the Additel ADT223A<\/h2>\n<p>The <strong>Additel ADT223A has been discontinued by Additel<\/strong>.<\/p>\n<p>For new installations and replacement requirements, users should therefore consider Additel&#8217;s current multifunction documenting process calibrator platform.<\/p>\n<p>The current <strong>Additel ADT227<\/strong> series offers modernized process calibration capabilities including a large smartphone-like touchscreen interface, USB Type-C and Bluetooth communications, IP67 protection, dual pressure module ports and significantly improved electrical performance.<\/p>\n<p>A HART-equipped version of the current platform is available as the <strong>ADT227-HART<\/strong>.<\/p>\n<p>For existing ADT223A users, europascal can assist in evaluating the appropriate current Additel solution based on the required pressure, temperature, electrical and HART calibration workload.<\/p>\n<h2>ISO\/IEC 17025 Accredited Calibration<\/h2>\n<p>The <strong>Additel ADT223A<\/strong> was supplied with an:<\/p>\n<p><strong>ISO\/IEC 17025 accredited calibration with measurement data<\/strong>.<\/p>\n<p>This supports metrological traceability and documented verification of the calibrator&#8217;s performance.<\/p>\n<p>Regular calibration remains important for existing ADT223A instruments that continue to be used in professional calibration applications.<\/p>\n<p>At <strong>europascal<\/strong>, we provide professional calibration services for pressure, temperature and electrical measurement equipment.<\/p>\n<p>For further information about calibration and
