Explain what checks should be done to an electrical measuring device before attempting to measure electrical resistance?

Before measuring electrical resistance with a device, ensure that the device is properly calibrated and functioning correctly. Check that the probes are clean and in good condition to ensure accurate readings. Additionally, ensure that the circuit is de-energized and that any capacitors are fully discharged to prevent damage to the measuring device. Finally, confirm that the selected measurement range is appropriate for the expected resistance value.
