- Frequency -
- Expressed in the unit of Hz (hertz). Commercial frequency of 50Hz/60Hz can be measured.
- Capacitor -
- Capacitor capacity (electrostatic capacity) is measured and expressed in the unit of F (farad), μF, etc.
- Duty cycle -
- The duty cycle of repeating waveform is indicated on a percentage basis (%). It can be used for the analysis of control signals.
- Continuity buzzer -
- The buzzer sounds when the measuring object is electrically conducting.
- Auto power off -
- Power is automatically turned off when a certain time has elapsed after power-up. Some models have a function to cancel this function.
- Data hold -
- A value indicated on the display is fixed. It is fixed even after the test lead is removed, and can be used as a record for reference purposes.
- Measurement of relative value -
- A certain measured value is assumed as 0 and measured values after that are expressed by positive or negative values relative the value fixed as 0.
- Low power ohm (Ω) -
- Resistance is measured by applying voltage of approximately 0.4V or less on a measuring object. It is characterized by the fact that the semiconductor does not conduct at approximately 0.4V or less even in forward direction.
