38、nstruction 4.1.1 General All parts of the apparatus, including the sensors and probe, shall be constructed of materials that will not be affected by vapours and gases or chemical substances typically found in the environment in which it is intended to be used see 4.2.2 c). The apparatus shall confor

39、m to IP40, in accordance with EN 60529:1991, Clauses 12 and 14. Adjustments that might affect the performance of the apparatus shall be suitably protected against unauthorized changes, such as through the use of passwords, tamper-evident seals or special tools. 4.1.2 Power supplies Apparatus which d

40、erives its power from internal batteries may give a visual warning before the battery capacity falls to a point where either the apparatus sensitivity or the stated display accuracy falls outside the requirements. When this point is actually reached, a clear indication shall be given to alert the us

41、er and the display shall switch out of normal operational mode. Apparatus provided with the means of connection to the mains supply shall conform to relevant EN standards. BS EN 50543:2011EN 50543:2011BS EN 50543:2011- 7 - EN 50543:2011 NOTE This area is covered by various statutory regulations. 4.1

42、.3 Indicators 4.1.3.1 Indicators shall be provided to show: a) measured parameter, values and units of measurement; b) low battery warning for battery-powered apparatus; c) for aspirated apparatus with an integrated flow indicator, a warning when a blockage occurs (see 5.3.14); d) mode of operation

43、or apparatus status (e.g. warm-up and measurement); e) when values lie outside the indicating range. All values shall be indicated on a display with characters not less than 8 mm high, unless adequate provision is made for enhancing the legibility (e.g. backlighting), in which case the minimum chara

44、cter height shall be 4 mm. For each separate parameter measured the apparatus shall display the value, the physical unit and parameter description. For a combination of parameters the display may switch automatically from one indication to another. If the display switches between information of simu

45、ltaneous parameters it shall be clear and understandable. Displayed measured values shall be refreshed at intervals no greater than 3 s. If the apparatus is equipped with seven-segment displays it shall have a device or self testing function for checking the displays. 4.1.3.2 For aspirated apparatus

46、, a means shall be provided to recognise and/or indicate the working mode of the pump (or a blockage of the gas path) by, for example: audible warning; visual indication; or flow measurement. 4.1.4 Range, resolution, accuracy and response time 4.1.4.1 Table 1 lists the different parameters covered b

47、y this European Standard. For each parameter given it specifies the: minimum indication range; maximum display resolution; accuracy of the apparatus; maximum response time. 4.1.4.2 The indication ranges are the minimum ranges for the apparatus. Higher ranges are allowed, but will not change the valu
