Operating instruction book 6171-728
Optional Accessories
Earth testing kit 6310-755
Comprising carrying case and pouch containing:
Four galvanised steel spikes (‘L’ shape) 10 mm dia. (0.4 in. dia.
approx) x 350 mm (14 in. approx) long
30 m (98,5 ft approx) of cable on a winder

Resistivity tests assist in the design of a correct earth
system and avoid the cost of re-working electrode
installations.
Earth testing kits, which include suitable test spikes and
test leads, are available separately.
