An additional power supply is not necessary. An additional power supply is not necessary.The instrument is con�gured using three buttons which are located under the front cover. A logically structured menu guides the operator through all the necessary programming steps using simple characters on the LCD panel. It is possible to set the indication range and both o�set and slope correction. In addition, if required, a �lter can be activated and set in various stages. The �lter suppresses short spikes and thus enables the easy readability of the display.All programmed parameters are stored in an EEPROM and are preserved in the event of power outage.The model A-IAI-1 attachable indicator has been developed speci�cally for use in hazardous areas. This attachable indicator can be combined with Ex transmitters and also with a repeater power supply (e. g. model IS Barrier) or an Ex galvanic isolator, thus enabling its use in zone 1 areas.The attachable indicator has its own integrated self-diagnostics, which continuously monitors that the key components of the instrument are working properly. The integrated self-diagnostics, as well as the reporting of an over-range or under-range condition, ensure high operational safety.With its robust and compact plastic case, the attachable indicator ful�lls the ingress protection IP65 and is thus exceptionally suitable for a wide range of industrial applications.
