Ystyr NCV yw Non-Contact Voltage detection. This function allows the meter to detect the presence of AC voltage in a wire or socket without physical contact, usually alerting the user via a buzzer or LED indicator.
Before use, visually inspect the insulation of the test leads for any cracks or damage. Ensure the metal wire is not exposed. Generally, you can also perform a continuity test by touching the two probes together; the meter should beep or show near-zero resistance.
'OL' stands for Over Limit or Over Load. It indicates that the value being measured is higher than the currently selected range. If this happens, switch to a higher range or 'Auto' mode if available.
