14. Mode signal To locate leaks Detection mode is semi quantitative that is it gives an audio and visual signal which increases as a leak is approached a higher gas concentration and decreases as you move the probe away from the leak It does not display figures In this mode of operation leaks can easily be detected using a sensitivity which can be preset Leaks can be located very accurately even when there are other leaks nearby If for example you are trying to locate a leak on a refrigerator condenser tubing and the tubing has a major leak then you will get an audio signal as soon as the probe is placed close to the condenser tubing When the probe is moved around over the condenser the signal will increase as the probe approaches the leak If the signal goes off the scale simply reduce the sensitivity setting to bring the signal within the scale By working with the sensitivity setting in this way you will be able to locate multiple leaks that are in close proximity to each other Do not expose the probe to more gas than is necessary because it will slowly saturate with time It is good practice to detect a leak locate it and immediately remove the probe to avoid saturation The probe is not damaged by the exposure but it will recover more slowly After excessive exposure it will be less sensitive for a short period of time Background compensation There is always some hydrogen gas in the background In fresh air this is as low
15. ON Sweden If the detector gets outer damage it must be controlled and repaired by service organisation authorised by INFICON Do not expose the probe to a hydrogen concentration higher than 0 1 6 when the instrument is not put into operation this might damage or destroy the probe sensor Note e When the instrument is put into operation the sensor withstands temporary exposure to hydrogen concentration up to 100 Avoid long exposures to high concentrations OP Sensistor ISH2000 HySpeed EN 201203 Hydrogen leak detector Sensistor ISH2000 HySpeed Operating Instructions 7 Calibrate the leak detector EN 7 1 Introduction The leak detector is the instrument and the probe together This section of the user manual consists of step by step examples about how to calibrate the detector in the most common cases For more about the calibration routine see the reference section The instrument must be calibrated by using the integrated calibration function to make sure it displays the correct values in Analysis Mode After calibration the instrument will show the correct measured values on the display in Analysis Mode The calibration parameters will be stored into the probe or in the Combox 7 2 Calibration reference There is a possibility to calibrate the detector by Reference Gas concentration A Reference contains a well defined concentration of Hydrogen gas in ppm mixed by air or some inert gas If you use premixed Refer
