Perform the SuperSting R8 Receiver Test

Perform a SuperStingR8 Receiver Test.  This is also a field level calibration check.

  1. Connect the SuperSting to an isolated 12V battery (raise off the ground onto wood or plastic and make sure no other devices are plugged into the Battery such as chargers or other electronics)
  2. Remove any switchboxes and connect either the SuperStingR8 Adapter Box Receiver Test Port (2016 and newer models) or the Test Box.  The Test Box is a small black box with single round port that is included with models older than year 2016.  Use the 1 meter yellow patch cable to connect one of these test devices. 
  3. Turn on the SuperSting 
  4. Choose Test Menu 3
  5. Choose Receiver Test 3
  6. Press MEA to run the Receiver Test

You should soon see 8 values close to 500mohm (+-5%).  The acceptable range is 475 to 525 mohm. 
If not, try an alternate 2m extension cable and run again.
Check all barrel connections to make sure they are 100% fully rotated.  Do not turn the strain relief or back portion of the connectors.  Only turn the smaller round ring that locks the connectors.  If they do not turn easily, they need to be ultrasonically clean.  Please contact AGI for instructions or to arrange cleaning at AGI.
If the Receiver Test is OK, proceed to Relay Test

Note:  Cables and the electrode stake to earth interface are the primary source of data noise.  Another source of data noise is improper power.  This can be from low voltage battery (<12V), other devices connected to the battery such as chargers and batteries that ground to earth partially by sitting directly on the earth.  Cables are susceptible to wear and tear and connector contamination.  The system uses high voltage and with the passive cable design, both high and low signal path wires are close to each other, so the connectors need to be clean and moisture free.  The Dual-Mode cables with internal switching electronics do not have this issue due to a patented design of the cable.  It is always best to keep the end caps on the cable connectors closed when not connected and to hand coil the cables.  Never drag or pull resistivity cables on the ground.  If both the Receiver Test and Relay Test pass, noise issues are related to the cables and the electrode to earth interface (contact resistance and stability).
