HY-OPTIMA™ 2620 Explosion Proof Area Hydrogen Monitor OPERATING MANUAL 9 STARTUP The monitor is designed to be exposed to an air background gas with no hydrogen most of the time. For optimal performance keep any hydrogen exposure to the sensor to less than one hour. If the hydrogen exposure exceeds this time, the sensor may need to be reconditioned by leaving it powered on in air for a few days. 9.1 OPTIONAL PRESSURE SENSOR If the pressure sensor was not installed and configured at H2scan the “PS” command must be used to setup the pressure sensor. (See section 14.10 PS COMMAND) If the sensor was...
