SQJ44-5A digital DC Bridge I. Overview & # 160; SQJ44-5A type digital DC bridge is QJ44 DC arms bridge the digital product, designed for a variety of small resistance (such as lead resistance, resistance welding, relay contacts the contact resistance, etc.), precision measurements can also be used to measure the DC resistance of the mining industry of distribution transformers and small motor windings. This product uses the LSI and 4 1/2 digit LCD display, a portable structure design, intuitive readings, clear, high speed, small size, easy to carry, etc., the more SQJ44 greater improvement are: included standard Resistance for whatever occasion, the product can be easily check to confirm the reliability of the measurement results. Second, the major technical indicators & # 160; 1, the technical parameters: Range Range resolution reference error limit 2mΩ 0.1μΩ ~ 1.9999 mΩ 0.1μΩ ± (0.5% of reading + 0.2% full scale) 20mΩ 1μΩ ~ 19.999 mΩ 1μΩ ± (0.2 % of reading + 0.05% full scale) 200mΩ 10μΩ ~ 199.99 mΩ 10μΩ ± (0.1% of reading + 0.02% full scale) 2Ω 100μΩ ~ 1.9999Ω 100μΩ ± (0.1% of reading + 0.02% full scale) 20Ω 1 mΩ ~ 19.999Ω 1 mΩ ± (0.1% of reading + 0.02% full scale) 200Ω 10 mΩ ~ 199.99Ω 10 mΩ ± (0.05% of reading + 0.02% full scale) model & # 160; No maximum test current range settings SQJ44-3A 3A 20 mΩ / 200 mΩ / 2Ω / 20Ω / 200Ω SQJ44-5A 5A 2mΩ / 20mΩ / 200mΩ / 2Ω / 20Ω SQJ44-10A 10A & # 160; & # 160; & # 160; & # 160; & # 160; & # 160; & # 160 ; 2, range setting: & # 160; & # 160; & # 160; 3, ambient conditions: temperature 5 ~ 35 ℃, relative humidity of 25% to 75% 4, Power supply: mains AC220V, 50Hz 5, Dimensions : 240 (D) × 320 (width) × 160 (high) mm 6, weight: about 4kg
