| The INFINITY® The INFU universal meter is ideal for those who want a single meter to cover a variety of input needs. This meter can measure a broad spectrum of dc voltage and current ranges, nine thermocouple types, a variety of RTDs, a multitude of inputs from pressure transducers, load cells, strain gages as well as potentiometric inputs. Six full digits make this meter ideal for demanding process control applications. On-board excitation is included so you can power virtually any sensor or transmitter, and four standard setpoints give the flexibility to control or alarm your system completely. The various setpoints can be configured as active above or below, latching or non-latching, as either high deviation, low deviation or band deviation, as well as numerous other possibilities. The meter is delivered configured for the input type you choose. The meter can be easily reconfigured using the front pushbuttons or via either of the optional serial communications boards. All options are field installable, so you can easily upgrade as your needs change.
