คู่มือการใช้งานและคำแนะนำการใช้มัลติมิเตอร์

This category acts as a centralized repository for user manuals, instructions, and safety guides related to general มัลติมิเตอร์ products that do not fall under a specific major manufacturer brand. These devices are often identified simply as "Digital Multimeter", "Smart Multimeter", or by model numbers such as ADMS7, S830, and FY76.

The documentation provided covers essential functions including AC/DC voltage measurement, resistance testing, continuity checks, capacitance measuring, and Non-Contact Voltage (NCV) detection. Users can find technical specifications, battery replacement guides, and safety warnings to ensure proper operation of these essential electrical testing tools.

• What is the NCV function on a multimeter?

  NCV ย่อมาจาก 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.

• How do I safety check my multimeter test leads?

  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.

• What does 'OL' mean on the multimeter display?

  '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.
