Intended Use
— Calibration by one person even in areas subject to explosion hazards.
— For connection to Dräger central units or to a programmable logic controller (PLC) to warn against physiologically harmful
gas concentrations.
— The optional display on the transmitter indicates the actual gas concentration and makes calibration easier.
False alarms during calibration are avoided by a special maintenance mode with output of a maintenance signal.
