Pleaseobserveherebythattheanglebetweenthewebplaneand

- Withwebwidthsfromthreemetersupwards,themetaldetector
mustbeadditionallysupportedinthemiddle.Seealsothetechni-
caldatasection.
- Relativemovements(vibrations)ofthemetaldetectorwithrespect
toothermetalparticlesmaytriggeranincorrectsignal.Thusitis
verymportantthatthemetaldetectorisnotsubjecttovibrations.
Whenmountingthemetaldetector,pleaseusetherubber-metal

- Twometaldetectorsshouldbeatleast3metersapart.
- Metalpathrollerswithadiameterofupto80mmshouldbelo-
catedataminimumdistanceof500mmtotheprobe.Thisisim-
portantbecauseiftherearecompensatingcurrentsthroughthe
pathrollerstheyinterferewiththecorrectfunctionofthemetal
