Pole Tester User Manual Operator INDUSTRI 2 Principle of the THOR Pole Tester The instrument detects analyses and records the signal of a series of stress waves entered into the pole by the hammer On board processors analyse the signal based on the duration of the wave form against the impulse force and provides the operator with a visual clue as to the state of the pole When the force is applied to the pole from the impulse hammer the stress wave travels up to near the top of the pole and down to near the base The location of the test is important so that the waveform for the signal results in the most effective analysis i i i Height of Test Zone Signal Response In presenting this response the THOR Pole Tester doesn t provide the end user with an engineering analysis of the pole but a general indication of the pole condition An important feature of the THOR Pole Tester is that the recorded wave form is able to be re assessed as algorithms and analysis tools improve Where the expected duration of the wave signal relative to the force is within a particular range the THOR unit provides the operator with a traffic light signal response of either green amber or red The on board analytics will be improved as more pole information is recorded and analysed PortaCAT Industries Pty Ltd 2015 Page 4 5 7 Groundline OS ENGINEERING Porta INDUSTRIES THOR Pole Tester User Manual Operator Eh

NN 3 Setting Up There are several items that need to be completed before an operator is able to progress to using the THOR Pole Tester in the field Once set up there is limited requirement to maintain these files Do not delete any of the system CSV files as all are critical to the operation It pays to charge the unit prior to their operation and a power adaptor is provided for this purpose It generally takes an hour or so to fully charge and the unit will advise when charging is complete With an efficient power management system on board a fully charged THOR unit will operate for at least a couple of days Power Supply Socket Pa C2 3 1 User Data User data in a comma separated value CSV format is able to be updated by Groundline Engineering with specific information or generic parameters e g UTILITY01 Otherwise a person can revise the User csv file themselves but they must keep the same format Any variation to the file will corrupt the operation of the THOR unit 3 2 Connecting Components First make sure that the rubber end of the hammer is attached firmly Continue to tighten every 4 or 5 poles to make sure the energy transfers properly through the bolt The components provided with the THOR Pole Tester are straightforward with the cables from the geophone and the hammer fastened into the base of the unit into the respective colour coded adapters These are not interchangeable between the hammer and geophone and no forcin
