Model SM-35X Multirange Panel Meter

The SM-35X is one of Texmate's new SM-series meter range. This range, which includes meters with LCD and LED displays, offers many unique features designed to simplify installation, calibration and scaling. All SM-35 and SM-35X meters are pincompatible, which enables LED and LCD meters to be interchanged within the same panel without necessitating wiring or panel cutout changes. All SM-series meters are 5 V DC powered with bipolar singleended inputs. The meters feature Display Hold, Display Test and Auto-Polarity indication. The polarity indication may be disabled or reversed by repositioning jumper clips on internal header pins. The SM-series of meters are designed to be user scalable to almost any engineering unit of readout. On-site scaling and recalibration is facilitated by multi-turn potentiometers that provide continuous fine and coarse adjustment within each of the three header-programmable full scale ranges. The three ranges provided with the SM-35X (LCD display ) and the SM-35 (LED display) are 2 V, 20 V, and 200 V full scale and both of these meters can be ordered with an optional zero-offset adjustment potentiometer. The SM-35XMV (LCD display) and SM-35MV (LED display) are specially designed for low voltage inputs and provide three header-programmable input ranges of 20 mV, 200 mV, and 200 V full scale. Both the SM-35XMV and SM-35MV have zero-offset adjustment potentiometers as a standard feature and a unique constant current power supply that eliminates any ground loop noise.
