Restek 22839 Instruction Manual

6.0 Lecks Finden Die Prüfspitze langsam and Dichtungen oder anderen potentiellen Leckquellen vorbeiführen. Wenn der Leak Detektor auf ein Gas (dass sich von Luft unterscheidet) anspricht, fängen der LED Lichter zu leuchten an, und wenn das letzte Licht erleuchtet hört man einen Alarm. Die roten LED Lichter bedeuten entweder Helium oder Wasserstoff Leaks. Die gelben LED Lichter zeigen Stickstoff, Argon, oder Kohlendioxyd Leaks an. Entfernen Sie die Prüfspitze von dem Leak und lassen Sie das Gerät auf Null zurückkommen. Wenn viel Gas in der Prüfspitze ist kann das ...

6.0 Detecting Leaks Slowly move the probe tip around fittings and other potential leak sources. If the Leak Detector senses a gas other than air, the LED bar graph will begin to light, and an alarm will sound when the last LED light illuminates. The red LED lights indicate helium and hydrogen leaks. The yellow LED lights indicate a nitrogen, argon, or carbon dioxide leak. Remove the probe from the vicinity of the leak and allow the unit to return to zero. If a large amount of gas has entered the probe, it may take a few seconds for the instrument to clear itself. Please d ...

The greater the number of red or yellow LED lights lit correlates in general to the size of the leak. NOTE: The Leak Detector is not a quantitative device, rather it is designed to detect leaks in gas line connections commonly associated with laboratory equipment. **CAUTION: This unit is designed to detect TRACE AMOUNTS of hydrogen arising from a small leak in a nonflammable environment, e.g., laboratory room air, etc. This unit is rated for use in a nonflammable atmospher ...

10.0 Technology The Leak Detector measurement is based on thermal conductivity comparisons between the probe air and a reference air. The device employs a dual thermistor technology which measures the ratio of [probe]:[reference] heat exchange values and displays the results on an LED scale (Figure 4). Under ideal operating conditions, a ratio of 1:1 indicates identical air samples for both [probe] and [reference], and therefore no leak is present. Because of slight differences in air temperature and/or humidity between the reference inlet (Figure 1) and the probe tip, a ...

Additional charges may apply if the warranty has expired or the unit is damaged due to misuse. Suggested Solution Possible Cause Problem Clean the probe tip to remove any debris Visually inspect probe line for holes* Recharge or return to Restek for battery replacement* Probe clogged Probe line punctured Weak battery Sensitivity decreased Re-zero detector Detector not zeroed Response decreased LED bar graph stays lit during operation Does not power up Ba ...
