If the test pressure is not 2 bar the value is converted accordingly see next chapter The default value is 1 min for medium sized watches and 2 min for small watches based on 2 bar The value for customer specific programs can be selected between 0 1 and 3 0 The lower the selected water resistance limit the longer the measuring time intervals needed for an accurate measurement 6 6 REFERENCE TO ISO STANDARD NIHS92 10 The ISO 2281 Standard states that a watch is to be considered as water resistant if less than 50 ug of air per minute penetrates into the watch at a test pressure of 2 bar A leak test based on the deformation principle does not allow the weight of the inflowing air to be directly measured Under specific assumptions it is however possible to establish a relation between the weight of the inflowing air and the deformation reversal With a medium size wristwatch free volume in the watch 2140 mm and a test pressure of 2 bar a flow of 50 ug of air per minute correspond to a deformation reversal of 1 per minute This value is set as the water resistance limit in the pre set programs The ISO 2281 standard does not take into account the volume of the watch Therefore the leak rate value of 50 ug per min is valid for all watches irrespective of their size In the test according to the deformation principle PROOFMASTER S the deformation reversal depends on the free volume in the watch A watch with a smaller
3. In the case of a small to medium leak it takes several minutes until the excess pressure has been released Thus a short test under water does not present any risk that water penetrates into the watch If the leak is very big however the excess pressure is released faster and there is some risk that water penetrates into the watch PROOFMASTER S measures the size of the leak with the Leakfinder Program and indicates to you if the watch can be immersed in water without risk Based on the size of the leak and the selected pressure the instrument computes the time during which the pressure has to be applied to the watch to create a high enough excess pressure in it Note Certain leaks due to a deformation of the case only manifest themselves at higher pressure and close again when the watch is under a normal pressure environment Such leaks cannot be located with the water test 3 2 TEST SEQUENCE Selecting the Leakfinder Program The Proofmaster S has two possibilities for selecting and using the Leakfinder Program The information for using the Leakfinder Program automatically appears on the display once a watch has completed the previous test with a poor result leaking The customer now has the choice to prepare the watch for locating the leakage in water by means of the Leakfinder Program or not The Leakfinder Program may be used as an independent test unrelated to other programs i e without previous test in Type Stnd Case another te
4. This allows deformations to reverse themselves If a watch is not leak tight an excess pressure builds up in it and according to the leak size it can take a very long time until the excess pressure has fully dropped In the case of test programs with 2 to 3 pressure values the previous pressure must always be lower than next pressure TIf 86 42 52 99 Fax 89 41 37 45 lindholts email dk www lindholts dk Lindholts Fourniturehandel ApS Sportsvej 6 8930 Randers N 7 FAULTY OPERATION 7 1 ERROR MESSAGES Implemented error messages are listed below Their meaning and fault removal are described The chamber opens again after it has been closed The test Measurement stopped vacuum or pressure cannot be built up Check the output No air pressure of the compressor It must exceed the selected test pressure by at least 1 bar If the input pressure is less than 8 bar or if the instrument is used at high altitude the highest achievable vacuum is reduced Switch to a program with lower vacuum Measurement stopped The chamber opens immediately again after it has been Sensor out of range closed The sensor exceeds the measuring range Check that the watch is correctly positioned The yellow LED sensor lights up when the sensor is correctly lowered Measurement stopped A big loss of pressure or of vacuum has been detected The chamber opens automatically Check the cleanliness of the sealing ring and of the supporting surface of th
