The Fieldbus Diagnostic Handheld FDH–1 is a comprehensive mobile measurement and commissioning tool for fieldbus segments. It can be used for connection to intrinsically safe FISCO systems or other intrinsically safe circuits up to level of protection “ia” according to IEC 60079-11. The device itself can be used in hazardous areas up to category 2G (zone 1).The device is not intended for the use within hazardous dust areas.
For advanced diagnostic features the equipment offers an USB port for data exchange with a computer and a trigger output for the use with an external oscilloscope. The FDH-1 can be powered from the fieldbus, the USB port or via a 9V block battery.
Depending on the usage and the type of externally connected circuits, according to the intended use there is a broad range of operating conditions, which are defined by the previously mentioned markings and the subsequently following references (see Annex to IECEx Certificate).
The permissible ambient temperature range is: -20°C to +50°C
