Texmate, Inc. Panel Meters SM-35MV-200

The SM-35MV is a 3.5 digit LED display panel meter designed for low voltage input measurements, specifically offering full scale ranges of 20 mV, 200 mV, and 2 V DC. It operates on a 5 V DC power supply and features a bipolar single-ended input configuration with a minimum input impedance of 1 MOc. The meter includes user-scalable options for various engineering units, and on-site calibration is facilitated through multi-turn potentiometers for fine and coarse adjustments. The SM-35MV provides additional functionalities such as Display Hold, Display Test, and Auto-Polarity indication, which can be customized by repositioning jumper clips. The accuracy of the meter is ¬±(0.05% of reading + 2 digits), with a typical temperature coefficient of 100 ppm/¬8C. It has a warm-up time of one minute to achieve specified accuracy and can process three readings per second. The display is a 0.56-inch high-efficiency LED, and the meter is suitable for applications requiring high DC current measurement with low voltage drop shunts. The device is housed in a compact case with dimensions of 69.68 mm x 29.72 mm and a depth of 84.2 mm, making it suitable for various panel mounting applications. The operating temperature range is from 0¬8C to 50¬8C, and it can withstand storage temperatures from -20¬8C to 70¬8C.
