Megger 梅凯 MIT220 兆欧表

"The MIT200 is one of the smallest insulation testers available on the market today. With options of a two voltage tester to a three voltage instrument, the MIT200 instruments offer a range of safety and operation features.Insulation testing to 1000MΩ. Dual & triple test voltages models. Digital display with electronic analogue arc display helps to confirm insulation condition & to monitor fluctuating readings not apparent on the digital display . Continuity testing at 200mA down to 0.01ohms resolution. Automatic discharge of circuit under test . 1mA test current at selected voltage range . Default voltmeter automatically switches in when the instrument is connected to a circuit with an AC or DC voltage greater than 25V. Autoranging analogue arc scale shows only the scale in use . Live circuit warning above 25V, also inhibits insulation & continuity tests above 50V. Lead resistance compensation on continuity . Hands free continuity testing Auto power-down after 5 minutes . Complies with IEC 1010-1 safety standard installation Category III, 600V phase to earth. Conforms to EN61557-1. Tests to BS7671, 713-02, 713-03, 713-04, 713-06, 713-08, 413-04-04Tester Type = Insulation & Continuity TesterMinimum Test Voltage = 250V dcMaximum Test Voltage = 500V dcMaximum Insulation Resistance Measurement = 999MOhmsDisplay Type = LCDTest Current = 200mABattery Life = 3000 5-Second TestsMinimum Operating Temperature = -10°CMaximum Operating Temperature = +55°CPower Source = Battery"
