Calibrators

The Portacal 1000 and P275 calibration devices can be used to calibrate and set the analogue signal converters.

They provide clean smoothed, analogue standard signals and make use of a load indicator for quick loop diagnostics. As a hand-held signal source, they are optionally available as conventionally controlled (Portacal 275) and microprocessor-controlled (Portacal 1000) versions.

A variety of operating modes – such as voltage source, mV source, current source,current sink and adjustable continuous level and ramping functions (Portacal 1000) – makes them suitable for use during the installation and maintenance of processing plants.
