Our company prefer to source measuring instruments only from KKInstruments because they have a wider range of products and show a high standard of expertise. We are very happy with the deal. No regrets for choosing KKInstruments for the past 8 years,
The latest circuit design permits the instrument to operate with the minimum of influence from earth voltage and earth resistance of auxiliary earth spikes.
•
Dust and drip proof. (designed to IEC 529 IP54)
•
Earth resistance value can be read directly from the scale.
•
Designed to meet IEC 61010-1 safety standard.
•
Capable of measuring earth voltage.
•
Small and lightweight. Shock resistant new case material.
•
2mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test.
•
Lead wire connection to C and P terminals and proper auxiliary earth resistance can be checked by "OK" lamp. Lead wire connection to C and E terminals is good when "OK" lamp is illuminated.
