- Noise Check Function
A function to detect current, which effects on an earth resistance measurement and display “NOISE” mark on the LCD.
- Memory function
Save and display up to 100 measurement data.
- Data hold function / Buzzer function / Back light function
Compliant with Safety Standards of IEC 61010-1 : CAT IV 300V Pollution degree2
