milliammeter
/ˌmɪlɪˈamɪtə
/noun
An instrument for measuring electric current in milliamperes.As the sensitivity of such milliammeters is usually low, it is necessary first to amplify the polarographic current....
- For example, the milliammeter may be calibrated to read in cubic feet per minute.
- X-ray machines used for diagnosis or treatment therefore need to have voltmeters and milliammeters for proper adjustment.
