KYORITSU MODEL 4102A Analog Earth Tester | 3-pole and 2-pole measurement, 12 / 120 / 1200 Ω, earth voltage 0–30 V, IP54

KYORITSU MODEL 4102A Analog Earth Tester: Direct Scale Reading

Overview

The MODEL 4102A is a KYORITSU analog earth tester (soft case version; the hard case version is the MODEL 4102A-H) that reads earth resistance directly from the scale. When the OK lamp lights, the C and P terminal connections and auxiliary earth resistance are normal. With a 2 mA test current, it is unlikely to trip earth leakage breakers on the circuit during measurement.

Key Specifications

• Earth resistance: ×1 Ω: 0–12 Ω; ×10 Ω: 0–120 Ω; ×100 Ω: 0–1200 Ω; ±3% of full scale
• Earth voltage: 0–30 V AC (50 / 60 Hz), ±3% of full scale
• Standards and protection: IEC 61010-1 CAT III 300 V; IEC 61557-1, 5; IP54
• Power and weight: 6 × AA; 105 × 158 × 70 mm (with cover), approx. 600 g
• Supplied accessories: 7095A test leads (red 20 m, yellow 10 m, green 5 m), 7127B simplified measurement probe, two 8032 auxiliary earth spikes

Applications

• Earth resistance measurement for buildings, power distribution and equipment earthing.
