Test your Voltage indicator is working before you prove equipment is safe to touch.
\n
\n
Many workplace regulations require you to conclusively test that your tester is working correctly BEFORE and AFTER
\n
proving that equipment is de-energised and safe to work on.
\n
\n
A convenient 240V power outlet is not always readily available in the field to test your instrument.
\n
\n
Testing on low voltage or DC such as a vehicle battery does not conclusively prove your tester is functional on AC mains.
\n
Most instruments auto select the highest range >200V AC. Proving your tester is working on the range you will use to prove safe, will maximise\n your Duty of Care.

Standard 6472 earth tester with GroundFlex option for tower and structure testing
\n
Measures earth resistance of towers and structures with up to 4 legs with independant earth connected
\n

AEMC’s GroundFlex® Field Kit includes the GroundFlex® Adapter Model 6474 and Ground Resistance Tester Model 6472. This is the ONLY system on the market\n capable of testing ground resistance of individual power transmission tower legs, as well as total resistance without disconnecting the overhead\n ground wire – this alone is a huge time and money saver, not to mention a major safety improvement. Key features include testing both ground resistance\n of tower legs (individually and total) and overhead ground wires. This system tests leakage current through the tower legs and tests at frequencies\n up to 5kHz to profile impedance, which is important to characterize for lightning strikes.
\n
The 6472 distinguishes itself from other portable earth testers in that it has a test current of up to 250mA improving its ability to make accurate and repeatable measurements in poor soil conditions as frequently encountered in Australia.
\n
\n
The AEMC 6472 Earth Tester is several earth testers in one. It allows the user to perform all necessary earth measurements comprising:\n \n \n
\n
\n
Earth Resistance of an isolated electrode\n
\n
Earth Resistance of a connected electrode without disconnection by the Selective method\n
\n
Earth Resistance of a connected electrode without disconnection by the Stakeless method\n
\n
Soil Resistivity directly in Ohm-m by either the Wenner or Schlumberger methods\n
\n
Earth Bond Resistance (milli-ohmmeter)\n
\n
External AC and DC voltage measurement\n
\n

The 6474/6472-AU is an Australian derivation of the standard European & US 6474/6472 GroundFlex kit, developed in co-operation with Australian\n Power utilities and includes:
\n
1. 4x GroundFlex 5m sensors
\n
2. 50/25m test leads on A-frame reel for fast roll out and rewind. (100/50m optional)
\n
3. 4x Stainless steel helical stakes for strength, corrosion resistance and superior ground contact
\n
4. 2x Connecting leads and crocodile clips Cat 4, 600V
\n
5. 2x Connecting and CT leads 4m in length to reach pole transformer test points from ground
\n
6. 2x Heavy duty canvas bags accommodating instrument & accessories.
\n
7. 1x 6472/6474 Connection lead
\n
8. 6x BNC extension leads
\n
9. 2x C-clamps
\n
10. 1x Optical USB cable
\n
11. 1x Power adaptor and Australian power cord
\n
12. USB Stick with DataView software & User manual for set up, data storage, real time display, analysis, report generation and system configuration
\n
13. Calibration certificates
\n
14. Optional 100kA fused bridging lead with insulation piercing connectors for safe stakeless testing of HV earths when not bonded to LV earth.
\n
15. Optional 2 x SR182 Current Probes for 2-clamp (stakeless method)
\n
Ground measurement on towers with ground cable\n
\n
High-voltage lines are usually equipped with a ground cable to allow lightning to discharge to ground via the tower. As all the towers are all connected\n to this conductor, all the tower's resistances are in parallel. This means it is impossible to measure tower resistance using traditional 3-Point\n methods unless the ground cable is disconnected, which is a dangerous and time-consuming operation.\n
\n
Automatic recognition and display of input connections to match test
\n
The connections are displayed and flash if incorrect or absent for the test selected.
