If you don't hold the probes of the ohmmeter steady for five seconds, what error message will appear on the LED screen of the meter?

When using an ohmmeter, it is essential to maintain steady contact with the probes on the component being tested for a sufficient duration, typically around five seconds. This allows the instrument to accurately measure the resistance and display a stable reading. If the probes are not held steady for this required amount of time, the meter's internal software detects the instability in the readings, resulting in an error message on the LED screen.

The message "Err" indicates a general error condition has occurred due to the probes being lifted or moved prematurely. This prompts the user to correct their technique by re-establishing steady contact, which is vital for obtaining a reliable resistance measurement.

In contrast, other potential messages such as "Error," "Check Leads," or "Out of Range" may imply different issues. "Error" might suggest a broader issue that is not explicitly related to probe handling; "Check Leads" usually indicates a problem with the probe connections or the quality of contact with the component; and "Out of Range" signifies that the resistance being measured exceeds the maximum limit of the meter. The specificity of the "Err" message makes it clear that the problem is directly tied to the measurement process involving probe stabilization.
