Insert the certified calibration test film into the slot on the receiver optics.
Once alignment achieves the maximum possible voltage, perform a zero-calibration. This teaches the system to recognize the clean, ambient air conditions as the baseline (0 LEL-m). Ensure no hydrocarbon gases or heavy steam clouds are present in the path during this step. Maintenance and Optics Care

Mount the transmitter and receiver main enclosures onto the brackets. Do not fully tighten the pan-and-tilt adjustment bolts yet, as freedom of movement is required for optical alignment. Electrical Wiring and Connections
The Dräger Pulsar 7000 communicates its operational health via the 4–20 mA current loop. Decoded current values represent specific statuses: Current Output Status Meaning Action Required Normal Operation No action; measures gas concentration (0 to 5 LEL-m). 3.5 mA Maintenance / Inhibit Device is in configuration or test mode. 2.0 mA Beam Blockage Ensure no hydrocarbon gases or heavy steam clouds
