46. tional test parameters LevelTec Test Report 11 AgroTech DANETV mk AgroTech User manual The LevelTec user manual is 18 pages and formulated in Danish The manual is read and evaluated as part of this verification According to the user manual switching off the LevelTec alarm function can be done using two commands ALARMOFFXX and GYLLEOFFXX XX refers to the number of hours the alarm function shall be switched off However during the test it was only the command GYLLEOFFXX that actually switched off the alarm function It is recom mended that the user manual is updated accordingly Moreover it is recommended that the user manual is updated so it includes instructions for calibration of LevelTec In addition In general the user manual contains full information and it is clearly formulated Testing the function of LevelTec when the pressure sensor is covered by sand Normally slurry contains a certain amount of sand e g from the fodder or from the wheels of the machines moving in and out of the livestock housing systems Especially large amounts of sand are found in slurry from cow housing systems where sand is used as bedding material for the cows During storage the sand will sediment in the slurry storage tank under the formation of a base layer in the bottom of the tank Over time this sand layer will accumulate since it is difficult to pump this out even after mixing the storage tank Thus since the pressure sensor is
