4105A Earth Tester

DESCRIPTION

• In addition to the facility for precision measurement, test leads for simplified two wire

measuring system also supplied as standard accessories

(unit can be hung from the neck for simplified measurement)

• 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 60529 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
