| ◆ grounding resistance measurement unit | 
        
            | Measurement range | 0 ~ 600Ω resolution Ω | 
        
            | Measurement accuracy | 100Ω less than 5Omu ± 100Ω more than ± 15Ω
 when the ground voltage is greater than or equal to 4V at ● alternating current measurement, it deviates from the measurement accuracy. (In the case of more than 4V, the measured value will be lower.)
 | 
        
            | The measured current | 2kHz 12mA (constant current output) ● If you have connected to the ground side as hot-warning function, buzzer and the active-line lamp will work. (Operating by the detection voltage is 60V or more)

            | Measurement range | 20 / 300V resolution 0.01 / 1V | 
        
            | Measurement accuracy | ± 1% rdg ± 5dgt | 
        
            | hold | Measurement hold the display data at the push-button switch of the probe "←" to display the mark. It will be canceled and press it again. | 
        
            | Battery replacement | Battery voltage will display the B mark and less than or equal to 5V. And the measured values continue to use B mark display remains will appear in the lower. |
