Kyoritsu 4200 Earth Clamp Tester

KYORITSU 4200 Earth Clamp Tester

• The earth resistance from 0.05 to 1500Ω can be measured without the auxiliary earth spikes. (The Multiple Earthing System.)
• True RMS. Accurate true RMS readings of AC current including distorted waveform from 1mA to 30.0A
• 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

Note:
A single earthing can not be measured. (Only for Multiple Earthing System)
