What Does 200m Mean on a Multimeter?
When you see “200m” on a multimeter, it typically refers to the measurement range for resistance or voltage, and it indicates that the device is set to measure in milliohms (mΩ) or millivolts (mV).
Resistance Measurement
200mΩ Range:
- If your multimeter has a setting for resistance measurement and shows “200m,” it usually indicates that the multimeter can measure up to 200 milliohms.
- Milliohms are one-thousandths of an ohm, and this range is useful for checking very low resistance values in circuits, connectors, or components.
Application:
- This range is particularly important in applications where low resistance is critical, such as in power circuits, battery connections, and ensuring the integrity of electrical contacts.
Voltage Measurement
200mV Range:
- If the “200m” setting is on the voltage measurement mode, it signifies the multimeter can measure up to 200 millivolts.
- Millivolts are one-thousandths of a volt, making this range suitable for measuring small voltages, often encountered in sensitive electronics and signal circuits.
Application:
- This is important in applications like testing low-voltage power supplies, sensor outputs, or small signal levels, where precision is key.
Conclusion
Understanding the “200m” designation on your multimeter can help you select the appropriate setting for your measurements, ensuring accuracy and preventing damage to your multimeter. Always consult your specific multimeter’s user manual for detailed information on the settings and their functions.
