KIMO INSTRUMENTS Pressure Temperature Humidity Air velocity Airflow Sound level DF 110 CE Detector of refrigerant gases and hydrogen H DESCRIPTION OF THE DEVICE Batteries led Autozero led Leds of graphic visualisation of thresholds Activation deactivation On Off key key for the audible signal Sensitivity Manual autozero key PERFORM A MEASUREMENT gt Turn on the detector pressing the On Off key When it turns on the pre heating phase of the sensor begins This phase lasts 60 seconds During this phase all the visualisation leds of thresholds light one after the other A few second before the end of the pre heating phase all the leds blinks at the same time gt Place the probe as close as possible to the site of the suspected leak gt Slowly move the probe approximately 2 cm second in the direction to the possible source of the leak It is important to move the probe past the leak and to go back toward it The device responds to changes in gas concentration in the air Moving the probe allows to the device to respond properly to these changes gt If gas is detected the frequency of the beep repetition will increase as the detected gas concentration increases and the leds of graphic visualisation lights from the left low gas concentration to the right high gas concentration Manual and automatic autozero functioning The detector performs an automatic autozero every 2 s to set its mi
3. nimum threshold of detection This autozero allows to guarantee an optimum gas detection whatever the conditions of use contaminated environment temperature variations In case of detection according to the amplitude of gas measurement the automatic autozero will deactivate to guarantee a better location of the leak It will automatically reactivate after a return to normal conditions In case of high gas concentration with a wide contaminated area the automatic autozero can be not enough to detect precisely the location of the leak there will be a measurement saturation In this case it is possible to perform a manual autozero into the contaminated area to reset the detection and to get back to a progressive sensitivity when getting close to the leak source To perform a manual autozero please see next page Setting of the sensitivity lf the gas concentration is high press Sens key to set the sensitivity and like this to get a better identification of the leak source Please see next page for the details about the three different sensitivities ADJUST THE DEVICE Adjust the sensitivity gt Press the Sensitivity Autozero key to adjust the sensitivity of the device Mode Indicative measuring range g an Visual alarm Low sensitivity B on the device From 0 to 300 g an All the leds 8 for 300 g an Normal sensitivity Norm on the device From 0 to 30 g an All the leds 8 for 30 g an High sensitivity H
