SuperSting Error Codes

There are 3 error codes your SuperSting can generate: HVOVL, TXOVL and INOVL


This means that your Transmitter leads (A & B) are disconnected somewhere in your system.

A detailed explanation what to check for can be found here.

Here are some things to check for a poor connection (check for a disconnection or debris):

  • electrode stake to ground connection
  • electrode cable takeout to the stake connection
  • electrode cable connectors (are they connected and seated properly)
  • electrode cable connection to the SwitchBox
  • the 2 meter extension cable from the SwitchBox to the SuperSting. You can try reversing this cable by using the other gender of this connector.
    • Try running the Relay Test in Menu 3 of the SuperSting. If this test passes then this cable connection is good.
    • If the Relay Test give you an error you can reverse the 2 meter extension cable by using the other gender of this connector.
    • Should both of these fail try re-addressing the SwitchBox
  • Check all 3 fuses. On newer instruments you will find all three fuse holders on the SuperSting instrument face plate. On some old generations of SuperSting you may find all of some of the fuse holders inside the instrument box. The SuperSting instrument panels screws require a 9/64" (3.5mm) Allen wrench. 


This means that the Transmitter is unable to lock on to a stable contact resistance. There are various things that can cause a varying contact resistance and they are all related to a loose electrode stake-to-ground contact:

  • Check for a loose electrode stake. This connection must be solid.
  • Wind can cause cables to move which in turn will move the stake. Try to place electrode cables on flat ground rather than over a bush or tall grass which will act like a sail in the wind.
  • Traffic. Survey performed close to a road can experience a similar "Wind" effect as the vehicle passes near the electrode cables.


This means that the input voltage on one of the Receivers is beyond the acceptable range of the A/D converter. Try lowering the current output in Menu 6.1 of the SuperSting OR lowering the voltage of the transmitter in Menu 6.4.
