Troubleshooting Geonics EM31 EM38 EM34 and EM61 is often a straight forward process.
The most common problem that can be checked by an operator are batteries issues. Though Geonics instruments use little power, poor battery contact and low power are often the problem to check first, second, and third. Battery contact is deceiving. More than once an operator has reseated, wiggled, moved, poked, and prodded the batteries without fixing the problem. That is because the battery holders are designed to keep the batteries in place under adverse field conditions and therefore very tight. Translation, it is not always easy to install them. Once the batteries are properly seated, the equipment usaully works fine. Like most major battery manufacturers DuraCell offers good information about battery care at their website.
Another common mistake, which users who are using more than one type of Geonics geophysical instrument is to swap data logger cables. Cables used to connect each type of geophysical instrument to a data logger are different for each instrument. This means that a data logger cable for a Geonics EM31 will not work with a Geonics EM-38. The cables should be labeled so an operator can quickly confirm if they have the correct hardware.
