Assembling the Array Bar – Wenner Alpha Array

  • The Array Bar is attached to the TAR-3 Frame using the P1 and P2 probes. (see figure 1) above.
  • Group P1 and C1 on the opposite side to C2 and P2.
  • Use the locking nuts on P1 and P2 – remember to adjust the length of P1 and P2 so that they protrude further than C1 and C2.
  • P1 and P2 should penetrate the ground before C1 and C2!

Note: The Array bar and two extra probes weigh 2kg more than the standard Twin probe unit. (each probes weighs 0.185kg)
