Operator’s manual for the Newport INFS INFINITY strain, DC current and voltage meter with setup, configuration and troubleshooting instructions.
The Newport INFS INFINITY is a front‑panel configurable strain gauge meter that accepts 0‑20 mA, 4‑20 mA, unipolar and bipolar DC voltage, and potentiometer inputs. It provides a 6‑digit LED display, multiple output options (analog, BCD, relay, RS‑232/RS‑485) and extensive lockout and alarm features.
This manual covers safety considerations, unpacking, detailed wiring and jumper settings, scaling methods, lockout configurations, setpoint and alarm programming, optional output boards, external control lines, troubleshooting messages, full specifications, factory preset values and how to record your setup values.
