Follow the 6 steps below to perform a Relay Test.Note: If you want to do a P-line test with your SwitchBox, please see this article
- Make sure you remove any electrode cables from the SwitchBox and connect the SwitchBox to the SuperSting™ with the yellow extension cable.
- Power the SuperSting™ with an isolated 12V battery or generator type power supply connected to an ungrounded generator. NEVER use a 12V battery mounted in a vehicle as this can damage the systems and invalidates the tests. More details HERE.
- Turn on the SuperSting™.
- Select Menu 3, then press 4 on the keypad.
- Enter the starting and ending address (Example: 1 and 56 if you have a SwitchBox 56).
- Press F1 to start the test.
If the SwitchBox is correctly addressed and each relay is performing properly, you will see AB/off “OK” on each relay as the test progresses forward. This test also performs a low power test measurement to test both the transmitter and receiver functionality through the SwitchBox. If you see any errors, contact AGI (Support@agiusa.com).
Display during good tests:
A good switch will cycle through the following display on each electrode number:
Connection: AB B A OFF
Display during a failed test:
If the test fails, it will stop and the SuperSting™ will beep.
Make sure to Skip and Continue to the next Electrode # to confirm how many switches are failing. If all switches fail, you most likely have a connection issue, a blown fuse or the SwitchBox has been programed to different address values than you are expecting.
The cables can be tested with a special CMD file AGI can send you. This would be used for the full set of cables on a field survey with a 2D line installed. The line can be setup in a soccer field or other field with easy access nearby at ~1m spacing. Other than avoiding buried utilities and very high contact resistance, the actual geologic materials do not matter.
