    Technical Data VIBROTEST 60 12.5.5 Mounting / Adjustment To fasten the reference pickup, we recommend using a magnetic stand. Normally the reference pickup needs to be installed perpen- dicular to the surface to be scanned, so that a sufficient quantity of the reflected light is received by the pickup.
  • Page 169 VIBROTEST 60 Technical Data a) Strong "noise" from the shaft surface (irregular reflections due to striations or surface irregularities) and the relatively low voltage rise in the area of the refe- rence mark cause multiple triggering. b) If the distance is too large, the amount of light emitted is insufficient.
