USA<\/li>\n<\/ul>\n<h2>From Absolute Vacuum to 3,000 psi<\/h2>\n<p>The <strong>Winchester Model 1<\/strong> covers an exceptionally broad measurement range.<\/p>\n<p>The instrument measures from:<\/p>\n<p><strong>absolute vacuum<\/strong><\/p>\n<p>up to:<\/p>\n<p><strong>3,000 psi<\/strong><\/p>\n<p>or approximately:<\/p>\n<p><strong>207 bar<\/strong>.<\/p>\n<p>This broad span is one of the defining features of the Model 1.<\/p>\n<p>Conventional digital pressure gauges often require several individual ranges to maintain useful measurement performance across such a large span.<\/p>\n<p>The Winchester Model 1 takes a different approach.<\/p>\n<h2>Auto Ranging Technology<\/h2>\n<p>The central feature of the <strong>Winchester Model 1<\/strong> is:<\/p>\n<p><strong>A.R.T. \u2013 Auto Ranging Technology\u2122<\/strong>.<\/p>\n<p>The instrument incorporates multiple internal pressure sensors.<\/p>\n<p>The electronics automatically use the appropriate measurement range depending on the applied pressure.<\/p>\n<p>The operator does not need to manually switch between ranges.<\/p>\n<p>This makes the Model 1 particularly convenient when a calibration or test procedure covers widely different pressure levels.<\/p>\n<h2>Multiple Sensors in One Gauge<\/h2>\n<p>A conventional pressure gauge typically contains one pressure sensor optimized for a particular measurement range.<\/p>\n<p>The Winchester Model 1 uses multiple sensing ranges within one instrument.<\/p>\n<p>This enables the gauge to maintain useful reading-based measurement performance over a much broader pressure range.<\/p>\n<p>The practical objective is straightforward:<\/p>\n<p><strong>One Winchester Model 1 can replace several conventional digital pressure gauges.<\/strong><\/p>\n<p>This can simplify both field equipment and laboratory inventory.<\/p>\n<h2>\u00b10.1% of Reading Accuracy<\/h2>\n<p>Winchester specifies the <strong>Model 1<\/strong> with an accuracy based primarily on:<\/p>\n<p><strong>\u00b10.1% of reading<\/strong>.<\/p>\n<p>The manufacturer&#8217;s current specification additionally states:<\/p>\n<p><strong>\u00b10.01% of full scale \u00b1 one digit<\/strong>,<\/p>\n<p>with the applicable internal full-scale range depending on the measured pressure.<\/p>\n<p>Below 50 psi, the specified internal full scale is 50 psi.<\/p>\n<p>Above 50 psi, the specified full scale is 3,000 psi.<\/p>\n<p>This specification should be considered when determining the complete measurement uncertainty for a specific calibration application.<\/p>\n<h2>Why Reading-Based Accuracy Matters<\/h2>\n<p>There is an important difference between:<\/p>\n<p><strong>% of reading<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>% of full scale<\/strong>.<\/p>\n<p>With a conventional full-scale specification, the absolute permissible error remains related to the maximum range even when the actual measured pressure is much lower.<\/p>\n<p>A reading-based specification follows the actual measured value more closely.<\/p>\n<p>This is particularly useful when one pressure gauge is expected to cover a broad pressure range.<\/p>\n<p>The Winchester Model 1 combines this concept with automatic internal range selection.<\/p>\n<h2>Gauge Pressure Measurement<\/h2>\n<p>The <strong>Winchester Model 1<\/strong> can be used for conventional gauge pressure measurement.<\/p>\n<p>Gauge pressure is measured relative to atmospheric pressure.<\/p>\n<p>Typical applications include:<\/p>\n<ul>\n<li>Industrial pressure gauges<\/li>\n<li>Pneumatic systems<\/li>\n<li>Hydraulic systems<\/li>\n<li>Pressure transmitters<\/li>\n<li>Process pressure measurements<\/li>\n<li>Pressure calibration<\/li>\n<\/ul>\n<p>The wide measurement range allows the same instrument to be used for many different pressure applications.<\/p>\n<h2>Absolute Pressure Measurement<\/h2>\n<p>The Winchester Model 1 also functions as an:<\/p>\n<p><strong>absolute pressure gauge<\/strong>.<\/p>\n<p>Absolute pressure is referenced to absolute vacuum rather than atmospheric pressure.<\/p>\n<p>This expands the potential applications of the Model 1 beyond conventional gauge pressure measurements.<\/p>\n<p>The ability to perform both gauge and absolute pressure measurements within one instrument further reduces the number of separate pressure gauges required.<\/p>\n<h2>Vacuum Measurement<\/h2>\n<p>At the lower end of its range, the <strong>Winchester Model 1<\/strong> can measure vacuum.<\/p>\n<p>This allows the same digital gauge to be used for:<\/p>\n<ul>\n<li>Vacuum measurements<\/li>\n<li>Negative gauge pressure<\/li>\n<li>Absolute pressure<\/li>\n<li>Positive gauge pressure<\/li>\n<\/ul>\n<p>A single instrument can therefore cover applications extending from vacuum through atmospheric pressure and into high positive pressure.<\/p>\n<h2>Selectable Pressure Units<\/h2>\n<p>The Winchester Model 1 supports multiple pressure units.<\/p>\n<p>The manufacturer&#8217;s current specifications include:<\/p>\n<ul>\n<li>psi<\/li>\n<li>bar<\/li>\n<li>psia<\/li>\n<li>inH\u2082O<\/li>\n<li>inHg<\/li>\n<li>mmHg<\/li>\n<li>absolute pressure display<\/li>\n<\/ul>\n<p>Additional units can be configured depending on the instrument version and manufacturer configuration.<\/p>\n<p>This allows the gauge to be adapted to different industries and calibration procedures.<\/p>\n<h2>Temperature Compensation<\/h2>\n<p>The <strong>Winchester Model 1<\/strong> is temperature compensated over the range:<\/p>\n<p><strong>-10\u00b0C to +50\u00b0C<\/strong>.<\/p>\n<p>Temperature compensation is important because pressure sensor characteristics can change with ambient temperature.<\/p>\n<p>The internal compensation helps maintain the specified measurement performance across typical laboratory, workshop and field conditions.<\/p>\n<h2>Rugged Construction<\/h2>\n<p>The Winchester Model 1 is designed for demanding industrial use.<\/p>\n<p>A:<\/p>\n<p><strong>protective rubber housing<\/strong><\/p>\n<p>is supplied as standard.<\/p>\n<p>The housing helps protect the instrument against mechanical impacts during field use.<\/p>\n<p>Winchester describes the Model 1 as a rugged, shock-resistant digital pressure gauge.<\/p>\n<h2>Protected Pressure Connection<\/h2>\n<p>The pressure connection is designed with a:<\/p>\n<p><strong>setback thread<\/strong>.<\/p>\n<p>This design helps protect the pressure port if the instrument is accidentally dropped.<\/p>\n<p>Damage to pressure connections is a common problem with portable pressure gauges.<\/p>\n<p>Protecting the connection therefore contributes to the suitability of the Model 1 for field applications.<\/p>\n<h2>1\/4&#8243; NPT Male Connection<\/h2>\n<p>The <strong>Winchester Model 1<\/strong> uses a:<\/p>\n<p><strong>1\/4&#8243; NPT male<\/strong><\/p>\n<p>pressure connection.<\/p>\n<p>Suitable adapters can be used to connect the instrument to other pressure thread systems.<\/p>\n<p>At europascal, the gauge can therefore be integrated into different pneumatic and hydraulic calibration setups using appropriate pressure adapters and hoses.<\/p>\n<h2>Tool-Free Handling<\/h2>\n<p>Winchester highlights the mechanical connection design as allowing the gauge to be tightened and loosened without relying on conventional welded connection construction.<\/p>\n<p>This is intended to reduce the risk of mechanical damage during repeated installation and removal.<\/p>\n<p>This can be particularly advantageous when the instrument is regularly moved between different calibration systems.<\/p>\n<h2>Large Digital Display<\/h2>\n<p>The <strong>Winchester Model 1<\/strong> incorporates a large digital display designed for easy reading.<\/p>\n<p>A bright backlight improves visibility in:<\/p>\n<ul>\n<li>Calibration laboratories<\/li>\n<li>Workshops<\/li>\n<li>Plant environments<\/li>\n<li>Outdoor applications<\/li>\n<li>Poorly illuminated installations<\/li>\n<\/ul>\n<p>The straightforward single-line display also supports simple operation.<\/p>\n<h2>Battery Powered<\/h2>\n<p>The Model 1 operates using:<\/p>\n<p><strong>three AA batteries<\/strong>.<\/p>\n<p>Standard AA batteries simplify replacement during field use.<\/p>\n<p>Special battery packs or dedicated charging equipment are therefore not required for basic operation.<\/p>\n<h2>Battery Voltage Indication<\/h2>\n<p>The instrument provides:<\/p>\n<p><strong>battery voltage indication<\/strong>.<\/p>\n<p>This gives the operator information about the actual battery condition rather than relying exclusively on a basic low-battery symbol.<\/p>\n<p>For field calibration, this can help prevent unexpected interruption of a measurement.<\/p>\n<h2>Recertification Reminder<\/h2>\n<p>The <strong>Winchester Model 1<\/strong> incorporates a:<\/p>\n<p><strong>recertification date reminder<\/strong>.<\/p>\n<p>This feature helps users manage the periodic calibration of the reference instrument.<\/p>\n<p>The manufacturer specifies a:<\/p>\n<p><strong>10-year memory<\/strong><\/p>\n<p>for the recertification information.<\/p>\n<p>This is useful in quality systems where measurement equipment must be monitored and recalibrated at defined intervals.<\/p>\n<h2>Pressure Gauge Calibration<\/h2>\n<p>The Winchester Model 1 is particularly suitable as a reference or high-quality comparison instrument for pressure gauge testing.<\/p>\n<p>Combined with a pressure generator, a typical calibration setup consists of:<\/p>\n<p><strong>Pressure Pump + Winchester Model 1 + Device Under Test<\/strong><\/p>\n<p>The pressure pump generates the pressure.<\/p>\n<p>The Winchester Model 1 measures the applied pressure.<\/p>\n<p>The device under test is exposed to the same pressure.<\/p>\n<p>Its indication can then be compared with the Model 1.<\/p>\n<h2>Combine with Magnum Pro MVP-600<\/h2>\n<p>For pneumatic calibration, the Model 1 can be combined with the:<\/p>\n<p><strong>Magnum Pro MVP-600<\/strong>.<\/p>\n<p>Winchester and Magnum Pro offer this combination as the:<\/p>\n<p><strong>MVP-600WIN<\/strong>.<\/p>\n<p>This configuration combines the Model 1 digital pressure gauge with a pneumatic calibration hand pump.<\/p>\n<p>It provides a portable solution for pneumatic pressure and vacuum calibration.<\/p>\n<h2>Combine with Magnum Pro M-10<\/h2>\n<p>For high hydraulic pressure applications, the Winchester Model 1 can be combined with the:<\/p>\n<p><strong>Magnum Pro M-10<\/strong>.<\/p>\n<p>The corresponding system is offered as:<\/p>\n<p><strong>M-10WIN<\/strong>.<\/p>\n<p>The M-10 is capable of generating hydraulic pressure up to 10,000 psi \/ 700 bar.<\/p>\n<p>Because the Winchester Model 1 itself has a maximum measurement range of 3,000 psi, the permissible measurement range of the Model 1 must always be observed when using this combination.<\/p>\n<h2>Combine with Magnum Pro M-80<\/h2>\n<p>For particularly sensitive low-pressure applications, the Model 1 can also be combined with the:<\/p>\n<p><strong>Magnum Pro M-80 Low Volume Pressure Chamber<\/strong>.<\/p>\n<p>The corresponding configuration is:<\/p>\n<p><strong>M-80WIN<\/strong>.<\/p>\n<p>The M-80 provides very fine pressure adjustment from vacuum to approximately 80 psi.<\/p>\n<p>Combined with the auto-ranging Model 1, this creates a flexible low-pressure comparison system.<\/p>\n<h2>Pressure Transmitter Calibration<\/h2>\n<p>The <strong>Winchester Model 1<\/strong> can be used as the pressure reference in a transmitter calibration setup.<\/p>\n<p>A typical system consists of:<\/p>\n<p><strong>Pressure Generator + Winchester Model 1 + Electrical Calibrator + Pressure Transmitter<\/strong><\/p>\n<p>The pressure generator provides the pressure.<\/p>\n<p>The Model 1 measures the actual applied pressure.<\/p>\n<p>The electrical calibrator measures the output signal from the transmitter.<\/p>\n<p>For a conventional industrial pressure transmitter, this is frequently:<\/p>\n<p><strong>4 to 20 mA<\/strong>.<\/p>\n<p>The pressure input can then be compared with the electrical output.<\/p>\n<h2>Pressure Switch Testing<\/h2>\n<p>The Model 1 is also useful for pressure switch testing.<\/p>\n<p>Pressure is gradually increased until the switch changes state.<\/p>\n<p>The Winchester Model 1 displays the corresponding switching pressure.<\/p>\n<p>Pressure can then be reduced until the switch resets.<\/p>\n<p>This allows determination of:<\/p>\n<ul>\n<li>Switching pressure<\/li>\n<li>Reset pressure<\/li>\n<li>Switching hysteresis<\/li>\n<\/ul>\n<h2>Fewer Reference Gauges<\/h2>\n<p>One of the primary design objectives of the <strong>Winchester Model 1<\/strong> is to reduce the number of individual pressure gauges required.<\/p>\n<p>Instead of maintaining several gauges for different pressure ranges, the broad auto-ranging capability allows multiple applications to be covered with one instrument.<\/p>\n<p>This can provide practical advantages for:<\/p>\n<ul>\n<li>Equipment inventory<\/li>\n<li>Transportation<\/li>\n<li>Storage<\/li>\n<li>Calibration management<\/li>\n<li>Recertification costs<\/li>\n<li>Field service<\/li>\n<\/ul>\n<h2>Reduced Calibration Inventory<\/h2>\n<p>Every pressure reference used in a quality-controlled calibration environment requires periodic calibration.<\/p>\n<p>Using fewer individual gauges can therefore reduce the number of instruments that must be managed and periodically recalibrated.<\/p>\n<p>This is one of the key economic arguments behind Winchester&#8217;s auto-ranging concept.<\/p>\n<h2>Technical Highlights<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Feature<\/th>\n<th>Winchester Model 1<\/th>\n<\/tr>\n<tr>\n<td>Product type<\/td>\n<td>Auto-Ranging Digital
