The integrated electric pump generates the pressure and the internal controller automatically adjusts the pressure until the requested value is reached and stabilized.<\/p>\n<p>This significantly reduces manual effort, particularly during multipoint calibrations with increasing and decreasing pressure sequences.<\/p>\n<h2>Accuracy up to 0.01 % FS<\/h2>\n<p>Depending on the installed interchangeable ADT155 pressure module, the ADT 760A-MA provides a pressure accuracy of:<\/p>\n<p><strong>0.01 % FS<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>0.02 % FS<\/strong><\/p>\n<p>FS refers to the span of the installed pressure module.<\/p>\n<p>A variety of ADT155 internal pressure modules are available. Selecting a module that is appropriately matched to the actual application can improve absolute measurement performance compared with using only the maximum 25 bar range.<\/p>\n<h2>Pressure Control Stability<\/h2>\n<p>The pressure control stability is specified as:<\/p>\n<p><strong>0.005 % FS<\/strong><\/p>\n<p>The stability specification refers to the full scale of the installed internal pressure module.<\/p>\n<p>Stable pressure control is important for automated calibration because the device under test should be evaluated only after the reference pressure has reached a sufficiently stable condition.<\/p>\n<p>The combination of automatic generation and closed-loop control makes the ADT 760A-MA particularly useful for repetitive calibration procedures.<\/p>\n<h2>Gauge Pressure Measurement<\/h2>\n<p>The <strong>Additel ADT 760A-MA<\/strong> supports conventional:<\/p>\n<p><strong>Gauge Pressure<\/strong><\/p>\n<p>Gauge pressure is measured relative to the surrounding atmospheric pressure.<\/p>\n<p>A reading of 0 bar(g) therefore corresponds approximately to the current atmospheric pressure.<\/p>\n<p>Gauge pressure is widely used for industrial pressure gauges, transmitters, switches and process measurement systems.<\/p>\n<h2>Absolute Pressure Measurement<\/h2>\n<p>Unlike the ADT 760A-D and ADT 760A-LLP, the MA version also supports:<\/p>\n<p><strong>Absolute Pressure<\/strong><\/p>\n<p>Absolute pressure is referenced to an ideal vacuum.<\/p>\n<p>The relationship is approximately:<\/p>\n<p><strong>p_abs = p_gauge + p_atmosphere<\/strong><\/p>\n<p>The integrated barometric reference allows the ADT 760A-MA to determine atmospheric pressure and use this information to provide absolute pressure values.<\/p>\n<p>This makes the MA version significantly more versatile when both gauge and absolute pressure instruments need to be calibrated.<\/p>\n<p>For absolute pressure measurements, the additional uncertainty contribution of the internal barometric reference must be considered.<\/p>\n<h2>Integrated Barometric Reference<\/h2>\n<p>The <strong>Additel ADT 760A-MA<\/strong> incorporates a dedicated:<\/p>\n<p><strong>barometric reference<\/strong><\/p>\n<p>This enables switching between:<\/p>\n<ul>\n<li>Gauge pressure<\/li>\n<li>Absolute pressure<\/li>\n<li>Barometric pressure<\/li>\n<\/ul>\n<p>without requiring a separate external barometer.<\/p>\n<p>The integrated barometric reference is one of the main technical differences between the MA configuration and the D or LLP versions.<\/p>\n<p>For absolute pressure measurement, Additel specifies an additional uncertainty contribution of:<\/p>\n<p><strong>55 Pa<\/strong><\/p>\n<p>which must be considered together with the gauge pressure measurement specification.<\/p>\n<h2>Interchangeable ADT155 Pressure Modules<\/h2>\n<p>The ADT 760A-MA uses interchangeable internal:<\/p>\n<p><strong>Additel ADT155 pressure modules<\/strong><\/p>\n<p>The maximum module supports pressure generation and measurement up to:<\/p>\n<p><strong>25 bar \/ 375 psi<\/strong><\/p>\n<p>Lower-range modules are available for applications where improved performance at lower pressures is required.<\/p>\n<p>The interchangeable module concept allows the same calibrator platform to be adapted to different pressure ranges instead of permanently limiting the instrument to one internal sensor.<\/p>\n<h2>Six-Digit Pressure Resolution<\/h2>\n<p>Pressure is displayed with:<\/p>\n<p><strong>6-digit resolution<\/strong><\/p>\n<p>A wide range of engineering units is supported, including:<\/p>\n<ul>\n<li>Pa<\/li>\n<li>hPa<\/li>\n<li>kPa<\/li>\n<li>MPa<\/li>\n<li>bar<\/li>\n<li>mbar<\/li>\n<li>psi<\/li>\n<li>mmHg<\/li>\n<li>torr<\/li>\n<li>inHg<\/li>\n<li>inH\u2082O<\/li>\n<li>mmH\u2082O<\/li>\n<li>cmH\u2082O<\/li>\n<li>kgf\/cm\u00b2<\/li>\n<li>Custom units<\/li>\n<\/ul>\n<p>This provides flexibility for international and industry-specific calibration applications.<\/p>\n<h2>Four Measurement Channels<\/h2>\n<p>The ADT760A platform provides:<\/p>\n<p><strong>4 channels<\/strong><\/p>\n<p>These consist of:<\/p>\n<ul>\n<li>One internal pressure channel<\/li>\n<li>Two external pressure measurement channels<\/li>\n<li>One electrical measurement\/source channel<\/li>\n<\/ul>\n<p>Compatible external Additel pressure modules can therefore be connected in addition to the internal ADT155 module.<\/p>\n<p>This significantly expands the measurement capability of the calibrator and allows additional pressure ranges to be integrated into a single calibration setup.<\/p>\n<h2>Integrated Electrical Process Calibration<\/h2>\n<p>The <strong>Additel ADT 760A-MA<\/strong> provides integrated electrical measurement and source functionality.<\/p>\n<p>This is particularly useful for calibration of pressure transmitters.<\/p>\n<p>A conventional pressure transmitter may convert pressure into a:<\/p>\n<p><strong>4\u201320 mA<\/strong><\/p>\n<p>electrical output.<\/p>\n<p>The ADT 760A-MA can generate and measure the reference pressure while simultaneously measuring the electrical output of the transmitter.<\/p>\n<p>This allows a complete pressure-to-current calibration to be performed with one compact instrument.<\/p>\n<h2>mA and Voltage Measurement<\/h2>\n<p>The electrical channel supports measurement of process current and voltage.<\/p>\n<p>Typical applications include:<\/p>\n<ul>\n<li>4\u201320 mA pressure transmitters<\/li>\n<li>Voltage-output pressure sensors<\/li>\n<li>Process indicators<\/li>\n<li>Control system inputs<\/li>\n<li>Pressure switches<\/li>\n<\/ul>\n<p>Combining pressure and electrical measurement in one instrument reduces the amount of additional equipment required for field calibration.<\/p>\n<h2>Current Source and 24 V Loop Power<\/h2>\n<p>The ADT 760A-MA also provides electrical source and simulation functionality up to:<\/p>\n<p><strong>24 mA<\/strong><\/p>\n<p>An integrated:<\/p>\n<p><strong>24 V loop power supply<\/strong><\/p>\n<p>can be used to power compatible process transmitters during calibration.<\/p>\n<p>This is especially useful for two-wire 4\u201320 mA transmitters, where the ADT 760A-MA can provide the pressure stimulus, transmitter power and electrical measurement within the same calibration setup.<\/p>\n<h2>Pressure Switch Testing<\/h2>\n<p>The <strong>Additel ADT 760A-MA<\/strong> supports:<\/p>\n<p><strong>pressure switch testing<\/strong><\/p>\n<p>The automatic pressure controller varies the pressure while the electrical channel monitors the switching state.<\/p>\n<p>This allows parameters such as:<\/p>\n<ul>\n<li>Switching pressure<\/li>\n<li>Reset pressure<\/li>\n<li>Switch hysteresis<\/li>\n<\/ul>\n<p>to be determined efficiently.<\/p>\n<p>Automatic pressure generation is particularly useful for pressure switch testing because switching points can be approached more consistently than with purely manual pressure generation.<\/p>\n<h2>Built-In Filter and Liquid Trap<\/h2>\n<p>The ADT760A platform includes:<\/p>\n<p><strong>a built-in filter<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>a built-in liquid trap<\/strong><\/p>\n<p>These components help protect the internal pneumatic system against contamination introduced through the connected device or pressure tubing.<\/p>\n<p>Protecting the internal pump, controller and pressure module is especially important when the calibrator is regularly used in industrial field applications.<\/p>\n<h2>Optional Contamination Prevention System<\/h2>\n<p>Additel also offers an optional:<\/p>\n<p><strong>Contamination Prevention System (CPS)<\/strong><\/p>\n<p>for the ADT760A series.<\/p>\n<p>The CPS provides additional protection against contamination entering the calibrator from connected instruments.<\/p>\n<p>This can be particularly useful when calibrating pressure devices that have previously been operated with contaminated air or process media.<\/p>\n<h2>Modern Communication Interfaces<\/h2>\n<p>The <strong>Additel ADT 760A-MA<\/strong> supports:<\/p>\n<p><strong>Bluetooth<\/strong><\/p>\n<p><strong>Wi-Fi<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>USB<\/strong><\/p>\n<p>communication.<\/p>\n<p>These interfaces allow the instrument to be integrated into modern calibration and documentation workflows.<\/p>\n<p>Wireless communication is particularly useful for mobile calibration applications, while USB provides a conventional wired connection for data exchange and instrument management.<\/p>\n<h2>HART Communication with the MA-DL Version<\/h2>\n<p>The standard <strong>ADT 760A-MA<\/strong> should be distinguished from the:<\/p>\n<p><strong>ADT 760A-MA-DL<\/strong><\/p>\n<p>The DL version adds:<\/p>\n<p><strong>HART communication<\/strong><\/p>\n<p>This allows compatible smart transmitters to be accessed directly during calibration.<\/p>\n<p>For applications where HART configuration, diagnostics and digital transmitter communication are required, the MA-DL configuration should therefore be selected.<\/p>\n<h2>Data Logging and Task Documentation<\/h2>\n<p>The corresponding:<\/p>\n<p><strong>ADT 760A-MA-DL<\/strong><\/p>\n<p>also provides advanced data logging and task documentation functions.<\/p>\n<p>These features are useful for documented field calibration workflows where calibration procedures and measurement results need to be stored digitally.<\/p>\n<p>The standard ADT 760A-MA remains the appropriate choice when automatic pressure generation, pressure measurement and integrated electrical calibration functions are required without the additional DL functionality.<\/p>\n<h2>Compact Handheld Design<\/h2>\n<p>Despite its integrated electric pump, automatic pressure controller, precision pressure measurement system and electrical process functions, the ADT760A platform weighs less than approximately:<\/p>\n<p><strong>1.8 kg \/ 4 lb<\/strong><\/p>\n<p>This compact design makes the instrument particularly suitable for mobile calibration work.<\/p>\n<p>Instead of transporting a hand pump, reference pressure gauge, electrical calibrator and additional accessories, many common calibration tasks can be performed with one integrated system.<\/p>\n<h2>Typical Calibration Applications<\/h2>\n<p>The <strong>Additel ADT 760A-MA Automatic Pressure Calibrator<\/strong> is suitable for calibration and testing of:<\/p>\n<ul>\n<li>Gauge
