The test head needs no special maintenance but should be regularly cared for end of each working day see below The test head skin is made of natural rubber Latex Latex is ozone sensitive and the test head therefore must not be placed in full sunlight In the case of stand still for any length of time it is best to cover it with a cloth or something similar If the test head becomes dirty it should be washed with soapy water Do not use any solvents on it The skin is certainly very robust and relatively thick but can be damaged by sharp objects which would mean the test head was no longer functional Labtec does repairs or applies new skins in the works Essential caution There are some disinfectant agents that can damage the latex skin of the test head if full face masks are not rinsed 100 after disinfections and disinfectant resi dues therefore get onto the latex skin of the test head For this reason it is important to use only such disinfec tant agents as are free of phosphates aldehydes and phenoles No agents containing oil grease or sol vents must be used for the care of the head These all damage the skin of the head The life time of the test head is not a part of the guarantee Labtec GmbH D 74927 Eschelbronn Fax 49 0 6226 970204 e mail info labtronic de www labtronic de Page 10 Nothing shown in LCD displays Pressure values are shown in the LCD displays but not in the measurement w
