kyoritsu model 4200

category: earth tester

quick overview:

tag: #earth clamp testers

• 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)
