Earth tester แบบ Analog Kyoritsu 4102A

Earth Testers4102A 4102ASoft Case Model4102A-HHard Case ModelProduct Catalogue •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.4102A Soft Case Model4102A-H Hard Case Model MeasurementRangesEarth Resistance: 0~12 Ω/0~120 Ω/0~1200 ΩEarth Voltage [50,60Hz]: 0~30V ACAccuracyEarth Resistance: ±3% of full scaleEarth Voltage: ±3% of full scaleOverload ProtectionEarth Resistance: 276V AC for 10 secondsacross 2 of the 3 terminalsEarth Voltage: 276V AC for 1 minuteSafety StandardIEC 61010-1 CAT.III 300V Pollution Degree 2, IEC 61557Applicable StandardsIEC 60529 IP54Withstand Voltage3700V AC for 1 minutePower SourceR6P (AA) (1.5V) × 6Dimensions105(L) × 158(W) × 70(D)mmWeight600g approx.Accessories7095A (Earth resistance test leads) × 1set(red-20m, yellow-10m, green-5m)8032 (Auxiliary earth spikes) × 1set7127A (Simplified measurement probe) × 1setR6P (AA) × 6Neck strapInstruction ManualCarrying Case: 9084 (Soft case) : 9164 (Hard case)Optional7100A (Precision measurement cord set)
