Rangeable voltage meters (VPIs) have three ranges available in one meter, 0 to 200 millivolts DC with non-adjustable input, 0 to 5 volts DC with adjustable zero and span, and 0 to 10 volts DC with adjustable zero and span. These meters can accurately monitor a wide variety of transducers and transmitters in voltage type process applications. The end user can utilize one meter for a variety of desired readouts, selectable decimal points and ranges. Additionally, the meters have 12 or 24 VDC power options available. These LCD meters come in non-backlit and red, green, or amber backlighting. They also have user selectable annunciators. “°F”, “°C”, “PSI” and “%” are illuminated on the LCD by selecting the appropriate jumper.
