Understanding VOM Multimeter & Full-Scale

Click For Summary
SUMMARY

The standard VOM (volt-ohm-milliammeter) multimeter measures current with a full-scale range of 50 microamperes. This means that the maximum current it can accurately measure is 50 microamperes, which is indeed a microampere measurement. The VOM also measures other electrical parameters, such as voltage, by utilizing appropriate series and shunt resistors to extend its measurement capabilities beyond the full-scale current limit.

PREREQUISITES
  • Understanding of basic electrical concepts, including current and voltage.
  • Familiarity with multimeter functions and measurements.
  • Knowledge of series and shunt resistors in electrical circuits.
  • Basic principles of analog meter movements.
NEXT STEPS
  • Research the operation of analog multimeters and their measurement ranges.
  • Learn about series and shunt resistor configurations for current measurement.
  • Explore the differences between VOM and digital multimeters.
  • Study the principles of full-scale deflection in analog meters.
USEFUL FOR

Electronics students, hobbyists, and professionals who work with multimeters and need to understand current measurement techniques and the functionality of VOM devices.

Homework Statement



In my textbook, it says "the standard VOM " (volt-ohm-milliameter) multimeter uses a meter movement that measures current (typically 50 microamperes full-scale).

I am just having trouble understanding what this means, I looked up full-scale and found that it was the number of the largest amplitude of the signal, so if the VOM can only measure up to 50 microamperes shouldn't it be a microameter? I feel like I may be misinterpreting full-scale?

Yes, it is, basically, just a microampere meter.
It measures other ranges of amps, together with volts, through the use of suitable series and shunt resitors respectively.
