Clamp meter

UT-278A by Unit is a clamp meter for grounding resistance and leakage current. UT278A makes it possible to measure resistance without disconnecting the line as is the case with classical measurement. Measurement ranges: Resistance - 0.01~0.099 Ohm ±(1%+0.01 Ohm) - 0.1~0.99 Ohm ±(1%+0.01 Ohm) - 1~49.9 Ohm ±(1%+0.1 Ohm) - 50~99.5 Ohms ±(1.5%+0.5 Ohms) - 100~199 Ohm ±(2%+1 Ohm) - 200~395 Ohm ±(5%+5 Ohm) - 400~590 Ohm ±(10%+10 Ohm) - 600~880 Ohm ±(20%+20 Ohm) - 900~1200 Ohm ±(25%+30 Ohm) Current intensity - 0.00 mA ~ 9.95 mA ±(2.5%+1 mA) - 10.0 mA ~ 99 mA ±(2.5%+5 mA) - 100 mA ~ 300 mA ±(2.5%+ 10 mA) - 0.30 A ~ 2.99 A ±(2.5%+ 0.1 A) - 3.0 A ~ 9.9 A ±(2.5%+ 0.3 A) - 10.0 A ~ 30.0 A ±(2.5%+ 0.5 A) Functions and features: Automatic change of measurement ranges Measurement time: 0.5 s Measured current frequency: 50/60 Hz Current limit setting: 1 mA ~ 499 mA Resistance limit setting: 1 Ohm ~ 199 Ohm Over limit alarm: audible and visual Indication of incorrectly closed jaws Indication of exceeding the measuring range Automatic switch off Memory of readings: 99 4-digit LCD display Features: RS-232 port Power supply: 4x 1.5V battery (LR6) Display: 47 x 28.5 mm Jaw opening: 28 mm Dimensions: 285 x 85 x 56 mm Weight: 1160 g Accessories: Batteries, test rings, case
