Diagnostic Criteria Criteria Is a wall or other building element in a safe air dry condition Air dry is the moisture content that is normal and safe from moisture related deterioration or decay in buildings When the Protimeter MMS2 moisture meter modes are selected measured values are identified as DRY AT RISK or WET Is the surface temperature of a wall or other building element above or below the dew point Dew point is the temperature at which a given quantity of air becomes saturated 100 RH and forms dew or condensation If a surface is colder than the dew point condensation occurs When the Protimeter MMS2 Condensator Mode is selected to measure TDIFF the proximity of a surface to the dew point the instrument identifies either a NO CONDENSATION condition an AT RISK condition or a CONDENSATION occurring condition 20 Is a wall surface or other building element contaminated with hygroscopic salts or other conductive material Artificially high moisture meter readings may be obtained either in material that has been heavily contaminated by hygroscopic salts or in materials that are conductive by nature The presence or absence of nitrates and chlorides should be established when investigating suspected rising dampness situations in particular INS8800 Rev B Protimeter MMS2 Instruction Manual 5 Diagnostic Procedure Guidelines cont Item 1 The Search and Measure modes
