In many cases, the reasons canbe determined in this way and faults rectified.Connect a multimeter in the suitable measuring range according tothe wiring plan. The following table describes possible errors in thecurrent signal and helps to remove them:Error Cause Rectification4 … 20 mA signalnot stable– Fluctuations ofthe measuredvariable– Set damping according to theinstrument via the display andadjustment module or PACTware/DTM4 … 20 mA signalmissing– Electrical con-nection faulty– Check connection according tochapter "Connection steps" andif necessary, correct according tochapter "Wiring plan"– Voltage supplymissing– Check cables for breaks; repair ifnecessary– Operating volt-age too low orload resistancetoo high– Check, adapt if necessaryCurrent sig-nal greater than22 mA or lessthan 3.6 mA– Electronicsmodule in thesensor defec-tive– Exchange the instrument or send itin for repairThe below tables show typical examples for application-relevantmeasurement errors with bulk solids.
