E_AREA Effective Area of flow meter device. The effective area is required for flow cal cu la tions and is en tered to be the same as shown on the Thermo Brandt flow me ter la bel. The avail able range is:

Eng lish Unit Ver sion: 0.0000 to 500.0000 square feet.

Metric Unit Ver sion: 0.0000 to 100.0000 square meters.

þNOTE: Some flow me ter de vices use ‘K fac tors’ in stead of ef fec tive ar eas to de fine mass flow re la tion ships. Ef fec tive ar eas can be cal cu lated from given K fac tors. See For mulas, Sec tion 10.

þNOTE: Thermo Brandt flow meter de vices are spec i fied in square feet. To con vert to square me ters, mul ti ply the square feet value by 0.0929.

Standard Density. The standard density is required for mass flow calculations and is entered for the specific gas being measured. The standard density is entered at the standard reference temperature of 68 degrees F or 20 de grees C. The avail able range is:

Eng lish Unit Ver sion: 0.0000 to 2.0000 pounds per cu bic foot.

Metric Unit Version: 0.0000 to 40.0000 Kilograms per cubicmeter.

Temperature source. Available assignments are 0 = CONstant, 1 = EXTernal and 2 = RTD.

Temperature Constant. The temperature constant can be used for mass flow calculations when no external temperature inputs are available and is entered as the average gas temperature. The available range is:

Eng lish Unit Ver sion: -50.0000 to 900.0000 de grees F.

Metric Unit Ver sion: -50.0000 to 900.0000 degrees C.

RTD Calibration offset. The RTD calibration offset constant allows the user to offset the actual measured value from the direct RTD input. The value may be positive or negative and is entered in degrees F. The available range is :

Eng lish Unit Ver sion: -10.0000 to 10.0000 degrees F.

Metric Unit Ver sion: -10.0000 to 10.0000 degrees C.

External Temperature Zero. The External Temperature Zero is the lower range (4 milliamp zero) setting for the external 4-20 milliamp ‘temperature’ input channel. The available range is:

Eng lish Unit Ver sion: -50.0000 to 100.0000 de grees F.

Metric Unit Ver sion: -50.0000 to 100.0000 degrees C.

Temperature Zero Calibration. The Temperature Zero Calibration value is the 4 milliamp (zero) count value from the external 4-20 milliamp ‘temperature’ input channel. This parameter is used to calibrate the zero point of the incoming 4-20 signal from the external 4-20 temperature device. To calibrate the zero point of the incoming 4-20 signal, press the EDIT key. The screen will display IN4MA. Set the incoming signal for 4 milliamps (or connect an external 4-20 calibrator set for 4 milliamps) and press the EDIT key. The MST2000 will measure the external temperature input channel and save the new 4 milliamp reference to memory.

MST2000 specifications

The Tamron MST2000 is a groundbreaking optical device that showcases the company's commitment to innovation and quality in the world of photography and imaging. Designed for both professional photographers and enthusiastic hobbyists, the MST2000 delivers exceptional image quality, versatility, and ease of use.

One of the standout features of the Tamron MST2000 is its superior optical design. It incorporates advanced lens element configurations that minimize aberrations and distortion, ensuring sharp and vibrant images across the entire frame. The lens construction includes high-grade glass elements that enhance light transmission, resulting in crystal-clear images even in low-light conditions. This is particularly beneficial for night photography or indoor settings where lighting may be challenging.

The MST2000 also boasts an impressive zoom range, allowing photographers to capture a wide variety of subjects with ease, from breathtaking landscapes to intimate close-ups. Its robust zoom mechanism enables seamless transitions between focal lengths, helping users to adapt to different shooting environments quickly. The zoom is complemented by a fast and accurate autofocus system that ensures subjects are sharply focused, allowing photographers to capture fleeting moments with confidence.

In terms of build quality, the Tamron MST2000 is constructed with durability in mind. The lens features a weather-sealed body, making it resistant to moisture and dust. This design consideration allows photographers to shoot in diverse conditions without fear of damage, ensuring that the MST2000 is a reliable companion in any situation.

Another notable technology featured in the MST2000 is the vibration compensation system, which helps to reduce the effects of camera shake. This is particularly beneficial when shooting at slower shutter speeds or using longer focal lengths, allowing for clearer images without the need for a tripod.

For those who appreciate creative control, the MST2000 includes various customizable settings that enhance the user experience. Photographers can fine-tune parameters such as focus and aperture easily, providing them with the flexibility to achieve their desired artistic effects.

In summary, the Tamron MST2000 offers a sophisticated combination of advanced optical technologies, versatility, and user-friendly features. Whether capturing sweeping panoramas or intricate details, this lens is designed to meet the demands of today's photographers while inspiring creativity and exploration in every shot.
