1. JL269 Portable Gas Detector JL269 Portable Gas Detector User s Manual 1 Description JL269 gas detector for industrial use has a high performance and wide detecting range It can be used to detect methane natural gases propane LPG Hydrogen and other combustible gases and can help you to find the gas leaking sources easily 2 Features Sensor doesn t need to be calibrated Quick response to combustible gas leakage Additional Long and flexible gooseneck tube Adjustable sensitivity 30 Level light Tricolor show Low battery alarming indication The sensor fault self detection GAS DETECTOR PRR RRR ERE eel e High concentration protect 3 Specifications Detecting Gas Natural gas LPG Sensitivity Better than 50ppm Detection range Alarm LED 1 Green LED 2 Yellow LED 3 Red LED ppm Scale No Environment Temperature 40 C 70 C Humidity lt 95 RH non condensing Warm up time lt 20S Response time lt 10S Indication 30 levels of LED indication Green low concentration Yellow middle concentration JL269 Portable Gas Detector Red high concentration Alarming levels The shorter the buzzer sound interval the higher the concentration Battery 3 6 1600mAh Ni H chargeable battery Charge time 4h to 6h Using time of the battery gt 8h Weight 310g Dimensions 1 70mmx62mmx26mm 4 Structure and Functions 12 JL269 Portable Gas Detector 2 Flexible gooseneck 8 scale Up 3 Concentrati2. on LED scale down 4 Power LED Jack of charger Jack of earphone no Sensor fault LED 11 earphone included e FulscaelED 2 Batey OE e eee 5 Operation instruction 5 1 Turn on the detector Press and hold LD for about 1 second Power LED lights and the device begins to self test the 10 LED will light in turns Warm up time is 20 seconds When warm up finish the green power LED lights and all the alarm LED off the detector enter detecting status 5 2 Detecting Put the sensor into the gas environment and the LED and sound frequency will show the gas concentration of the environment With concentration increases first the green LED lights and the buzzer frequency increases When the concentration exceeds the first 10 levels detection range the alarming LED turns yellow and then turns red At the same time the sound frequency interval will turn higher When all LED turn red it means the concentration reaches the highest of the detection range At this point the C4 OL LED will light 5 3 Fault If there is something wrong with the gas sensor the detector can t work At this point the LA FAULT lights and all concentration LED off At the same time the buzzer gives sound of Didi Didi 5 4 Keyboard operation 5 4 1 Silence When alarming press both Lb and t the audible alarm is off When press them again the audible alarm is on 5 4 2 Zero adjustment If the de
