What should you do if your measurement tool indicates a high current unexpectedly?

When a measurement tool indicates a high current unexpectedly, it is essential to disconnect and troubleshoot before proceeding. This action is crucial for several reasons. High current levels can pose significant safety risks, including electrical hazards such as shocks, burns, or even equipment damage. By disconnecting the measurement tool, you eliminate the risk of further exposure to potentially dangerous conditions and protect both yourself and the equipment.

Troubleshooting the situation allows you to verify whether the high reading was due to a fault in the measurement circuit, a malfunction or calibration issue with the tool, or an actual hazardous condition present in the electrical system you are testing. This step ensures that you accurately assess the situation, understand the cause of the high current reading, and take the necessary actions to rectify the problem safely.

While adjustments to tool range or calling for assistance may be appropriate in various circumstances, they do not directly address the immediate risk posed by high current levels. There is a clear priority on ensuring safety first through proper disconnection and troubleshooting procedures.
