- 4000 counts
- Easy to read large LCD with backlight
- Large breaking capacity fuse 30kA
- K type thermocouple temperature measurement -20℃ ~ 300℃
- Thermo plastic elstomer, high resistance against drop shock

- True RMS (True root-mean-square value)
- True RMS value. AC current and voltage of a non-sine wave can be measured by true RMS values.
- 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.
- Continuity check
- The LED lights up when the measuring object is electrically conducting.
- Continuity buzzer
- The buzzer sounds when the measuring object is electrically conducting.
- Temperature measurement
- Temperature can be measured using a probe.
- Auto power save
- The display disappears to bring the device into the power-save state when a certain time has passed 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.
- Range hold
- The range is fixed in the measurement of varying voltage and current which is difficult to read in the auto range.
- 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
- 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.
- Backlight
- Allows indicator reading in a dark place.
