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?

In the context of using an ohmmeter, maintaining steady contact with the probes for a prescribed duration is essential for obtaining an accurate resistance measurement. When the probes are not held steady for at least five seconds, the meter's internal system detects this fluctuation or instability in the readings. To alert the user to the issue and prevent unreliable data, the meter displays an error message.

The message "Err" signifies a general error condition, which in this case is caused by the lack of steady contact with the probes. This serves as a prompt for the operator to ensure proper handling of the probes to obtain valid measurements. The other options do not specifically correspond to the function of indicating that the probes were not held steady; they suggest different types of messages that are not directly related to the contact issue described. Therefore, the correct answer highlights the importance of maintaining stable probe contact to achieve accurate readings when using an ohmmeter.
