The unit is an extremely versatile and cost-effective multifunction process calibrator, which replaces many single function instruments with a single compact handheld unit. The unit measures, sources and simulates most process signals and displays both input/output readings simultaneously.
Cold junction: Automatic or manual compensation for thermocouple cold junction temperature
Scaled readings: Process signals can be scaled into engineering units e.g. measure mA and read in °F or °C.
Step Output: Step output, up and down, using arrow keys.
Ramp Output: Programmable end points, rate and dwell.
Preset memory: Quick store and recall of three preset values.
Loop power: 24V loop power for mA measure and source.
