applications.<\/p>\n<p>The maximum compatible internal pressure module provides a measuring range of:<\/p>\n<p><strong>\u00b175 mbar<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>\u00b130 inH\u2082O<\/strong><\/p>\n<p>This corresponds to approximately:<\/p>\n<p><strong>\u00b17.5 kPa<\/strong><\/p>\n<p>Unlike higher-pressure calibrators, the LLP version is optimized for accurately generating, controlling and measuring very small positive and negative pressures.<\/p>\n<p>This is particularly important in applications where only a few millibars or even fractions of a millibar need to be measured.<\/p>\n<h2>Internal Modules Down to \u00b10.62 mbar<\/h2>\n<p>One of the most important features of the <strong>Additel ADT 760A-LLP<\/strong> is its interchangeable internal pressure module.<\/p>\n<p>Additel offers ADT155 modules with measuring ranges down to:<\/p>\n<p><strong>\u00b10.25 inH\u2082O<\/strong><\/p>\n<p>which corresponds to approximately:<\/p>\n<p><strong>\u00b10.62 mbar<\/strong><\/p>\n<p>This means the calibrator does not have to rely on the maximum \u00b175 mbar range for every application.<\/p>\n<p>A pressure module can instead be selected to match the required calibration range.<\/p>\n<p>This is particularly useful because the accuracy specification is related to the full span of the installed pressure module.<\/p>\n<h2>Accuracy of 0.05 % FS<\/h2>\n<p>The specified pressure accuracy of the LLP version is:<\/p>\n<p><strong>0.05 % FS<\/strong><\/p>\n<p>FS refers to the span of the selected internal pressure module.<\/p>\n<p>This point is particularly important when selecting the appropriate ADT155 module.<\/p>\n<p>For example, a very low differential pressure application can benefit from using a lower-range module instead of the maximum \u00b175 mbar module.<\/p>\n<p>Selecting a pressure range close to the actual calibration requirement helps optimize absolute measurement performance.<\/p>\n<h2>Pressure Control Stability of 0.005 % FS<\/h2>\n<p>The specified pressure control stability is:<\/p>\n<p><strong>0.005 % FS<\/strong><\/p>\n<p>The stability specification is based on the full scale of the installed internal pressure module.<\/p>\n<p>Stable pressure control is essential for low-pressure calibration because even small pressure fluctuations can become significant relative to the applied test pressure.<\/p>\n<p>The automatic controller allows the instrument to approach and maintain pressure setpoints without continuous manual adjustment.<\/p>\n<h2>Fully Automatic Pressure Generation<\/h2>\n<p>A major advantage of the <strong>Additel ADT 760A-LLP<\/strong> is its built-in electric pressure pump.<\/p>\n<p>A conventional differential pressure calibration setup can require several separate components:<\/p>\n<ul>\n<li>Low-pressure hand pump<\/li>\n<li>Precision reference pressure instrument<\/li>\n<li>Fine pressure adjustment system<\/li>\n<li>Electrical process calibrator<\/li>\n<li>Pressure tubing<\/li>\n<li>Test leads<\/li>\n<\/ul>\n<p>The ADT 760A-LLP integrates pressure generation, pressure control, reference measurement and electrical process functions into one handheld instrument.<\/p>\n<p>The operator enters the desired pressure setpoint and the instrument automatically generates and controls the requested pressure.<\/p>\n<p>This significantly simplifies repetitive multipoint calibration procedures.<\/p>\n<h2>Gauge and Differential Pressure<\/h2>\n<p>The <strong>Additel ADT 760A-LLP<\/strong> supports:<\/p>\n<p><strong>Gauge pressure<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>Differential pressure<\/strong><\/p>\n<p>This makes the instrument especially useful for low-pressure process instrumentation.<\/p>\n<p>Typical devices include:<\/p>\n<ul>\n<li>Differential pressure transmitters<\/li>\n<li>Low-pressure transmitters<\/li>\n<li>HVAC pressure sensors<\/li>\n<li>Filter monitoring transmitters<\/li>\n<li>Cleanroom pressure transmitters<\/li>\n<li>Airflow-related differential pressure instruments<\/li>\n<li>Pressure switches<\/li>\n<li>Low-pressure gauges<\/li>\n<\/ul>\n<h2>Differential Pressure Applications<\/h2>\n<p>Differential pressure measurement is widely used when the difference between two pressure points is more important than their absolute pressure level.<\/p>\n<p>Typical applications include:<\/p>\n<p><strong>Filter monitoring<\/strong><\/p>\n<p>A differential pressure transmitter can detect the increasing pressure drop across a filter as contamination increases.<\/p>\n<p><strong>Cleanroom monitoring<\/strong><\/p>\n<p>Very small pressure differences are used to maintain defined pressure cascades between rooms.<\/p>\n<p><strong>HVAC systems<\/strong><\/p>\n<p>Differential pressure can be used for monitoring ducts, fans, filters and airflow-related systems.<\/p>\n<p><strong>Flow measurement<\/strong><\/p>\n<p>Differential pressure across an orifice, nozzle or other primary element can be used to determine flow.<\/p>\n<p>These applications make the low-pressure capability of the ADT 760A-LLP particularly valuable.<\/p>\n<h2>Interchangeable ADT155 Pressure Modules<\/h2>\n<p>The ADT 760A-LLP uses interchangeable internal:<\/p>\n<p><strong>Additel ADT155 pressure modules<\/strong><\/p>\n<p>The maximum compatible LLP module has a range of:<\/p>\n<p><strong>\u00b130 inH\u2082O \/ \u00b175 mbar<\/strong><\/p>\n<p>Additional internal modules are available with substantially lower ranges.<\/p>\n<p>This modular design allows users to select a pressure sensor that is better matched to the actual calibration task.<\/p>\n<p>The internal pressure module is also removable, providing greater flexibility than an instrument with a permanently installed pressure sensor.<\/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 module channels<\/li>\n<li>One electrical measurement\/source channel<\/li>\n<\/ul>\n<p>The two external pressure channels can be used with compatible Additel external pressure modules.<\/p>\n<p>This significantly expands the measurement capability of the calibrator and allows additional pressure ranges to be integrated into the calibration setup.<\/p>\n<h2>Integrated Electrical Measurement Functions<\/h2>\n<p>The <strong>ADT 760A<\/strong>, unlike the simplified ADT760S, provides integrated electrical calibration functions.<\/p>\n<p>These include:<\/p>\n<ul>\n<li>mA measurement<\/li>\n<li>Voltage measurement<\/li>\n<li>Current source\/simulation<\/li>\n<li>24 V loop power<\/li>\n<li>Pressure switch testing<\/li>\n<\/ul>\n<p>This is particularly useful when calibrating pressure transmitters with an electrical output.<\/p>\n<p>A typical <strong>4\u201320 mA pressure transmitter<\/strong> can therefore be supplied with pressure, electrically powered and measured using the same portable calibrator.<\/p>\n<h2>24 V Loop Power<\/h2>\n<p>The integrated:<\/p>\n<p><strong>24 V loop power<\/strong><\/p>\n<p>allows compatible process transmitters to be powered directly during calibration.<\/p>\n<p>This eliminates the need for a separate external loop power supply in many field calibration applications.<\/p>\n<p>The combination of automatic pressure generation and electrical signal measurement allows complete transmitter calibration with a compact test setup.<\/p>\n<h2>Pressure Switch Testing<\/h2>\n<p>The ADT 760A-LLP also supports:<\/p>\n<p><strong>pressure switch testing<\/strong><\/p>\n<p>The integrated automatic pressure generator can vary pressure while the electrical channel monitors the switching state.<\/p>\n<p>This enables the determination of:<\/p>\n<ul>\n<li>Switching pressure<\/li>\n<li>Reset pressure<\/li>\n<li>Switch hysteresis<\/li>\n<\/ul>\n<p>without requiring separate pressure generation and electrical measurement equipment.<\/p>\n<h2>Built-In Filter and Liquid Trap<\/h2>\n<p>The current 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 features help protect the internal pneumatic system from contamination introduced through connected pressure instruments or tubing.<\/p>\n<p>This is especially useful during field calibration where the cleanliness of the device under test cannot always be guaranteed.<\/p>\n<h2>Optional Contamination Prevention System<\/h2>\n<p>Additel also offers an optional:<\/p>\n<p><strong>Contamination Prevention System<\/strong><\/p>\n<p>for the ADT760A series.<\/p>\n<p>This accessory provides additional protection for the internal pneumatic components when instruments with a higher contamination risk are connected.<\/p>\n<p>Contamination control can contribute to long-term stability and reduce maintenance requirements.<\/p>\n<h2>Modern Communication Interfaces<\/h2>\n<p>The <strong>Additel ADT 760A-LLP<\/strong> provides:<\/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 support integration into digital calibration workflows and communication with compatible Additel software.<\/p>\n<p>The combination of wireless and wired communication provides flexibility for both laboratory and field applications.<\/p>\n<h2>Optional HART Communication<\/h2>\n<p>The standard <strong>ADT 760A-LLP<\/strong> does not include HART communication.<\/p>\n<p>For applications requiring HART functionality, Additel offers the corresponding:<\/p>\n<p><strong>ADT 760A-LLP-DL<\/strong><\/p>\n<p>version.<\/p>\n<p>The DL configuration adds HART communication as well as additional documentation functionality.<\/p>\n<p>This distinction is important when configuring the product for smart transmitter calibration.<\/p>\n<h2>Optional Data Logging and Task Documentation<\/h2>\n<p>Data logging and task documentation are also associated with the:<\/p>\n<p><strong>ADT 760A-LLP-DL<\/strong><\/p>\n<p>configuration.<\/p>\n<p>The standard ADT 760A-LLP provides the pressure and electrical calibration functions required for conventional field calibration.<\/p>\n<p>Customers requiring advanced documentation, HART communication and task-based workflows should select the DL configuration.<\/p>\n<h2>Compact Handheld Calibration System<\/h2>\n<p>The ADT760A platform weighs less than:<\/p>\n<p><strong>4 lb \/ 1.8 kg<\/strong><\/p>\n<p>Despite its compact size, the instrument combines:<\/p>\n<ul>\n<li>Electric pressure generation<\/li>\n<li>Automatic pressure control<\/li>\n<li>Precision pressure measurement<\/li>\n<li>External pressure module support<\/li>\n<li>Electrical measurement<\/li>\n<li>Electrical source functions<\/li>\n<li>Communication interfaces<\/li>\n<\/ul>\n<p>This makes the ADT 760A-LLP particularly attractive for technicians who need to perform low-pressure calibrations directly in the field.<\/p>\n<h2>Technical Highlights<\/h2>\n<p><strong>Model:<\/strong> Additel ADT 760A-LLP<\/p>\n<p><strong>Device
