FeatureMeasure from very low (0.1μΩ) to very high (110MΩ) with single instrument.Along with capabilities for fast, precise measurements over a broad resistance range, AT512 also provides functions for comparator and PLC interface. Employing a four-terminal measurement method, AT512 is particularly suitable for measuring the resistance of motor and transformer windings, relay, switch and connector contacts, PCB patterns, inductor DC resistance and in shipping inspection tests.SpecificationParameter:DC resistanceAccuracy:0.01%Measurement Range:0.1μΩ～110MΩMeasurement current:Current range: 1μA~1ARange:Automatic and manual with 11 rangesSpeed:167 times/second, 60 times/second, 10 times/second, 2 times/secondDisplay:Show,ΔABS,Δ% and sorting resultDisplay Max:104000Adjustment:Open & short resetComparator:30 groups record, NG-LO, GD-IN, NG-HI display and output, adjustable beep and volumeTrigger:Internal, manual, external and remoteInterface:RS232C，Handler InterfaceTemperature compensation:Accuracy:0.2 °C Ranger: 0～80 °CMethod:4 terminal shielding(2 check terminal and 2 driving terminal) and external shielding ground sectionVoltage: 198V AC - 240V AC Frequency: 50Hz Power: Max 15VAExternal size: 264mm (Width)x107mm (Height)x350mm (Depth) Inside size: 216mm (Width)x88mm (Height)x323mm (Depth) 4kgATL501: Kelvin clip ATL801: 232 communication cableATL620: meter resistance 4-terminal test clipFour-color vacuum fluorescent screen VFD display Keypad lock and data hold function temperature compensation interface
