Introduction Kyoritsu 4200
This instrument is a digital clamp-on earth resistance tester, and it is used in multi- earthed systems. Can measure the earth resistance by simply clamping around the earthed wires. This instrument also equips AC current function to measure current up to 30A same as our traditional leakage clamp meters. A single earthing cannot be measured. (only for multiple-earthing system)
Features Kyoritsu 4200
• 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
