The SM-Series meters have LCD or LED displays and offer many unique features designed to simplify installation, calibration and scaling. All SM-35 and SM-35X meters are pin-compatible, 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 powered with bipolar single-ended inputs. The meters feature Display Hold, Display Test and AutoPolarity 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-35 (LED display) and SM-35X (LCD display) are 2V, 20V and 200V full scale and both of these meters can be ordered with an optional zero-offset adjustment potentiometer.
The SM-35MV (LED display) and SM-35XMV (LCD display) are specially designed for low voltage inputs and provide three header-programmable input ranges of 20mV, 200mV and 2V full scale. Both the SM-35MV and SM-35XMV have zero-offset adjustment potentiometers as a standard feature and a unique constant current power supply that eliminates any ground loop noise.
