Megger 梅凯 MIT230 兆欧表

"The MIT230 incorporates a range of safety and operation features in one of the smallest electrical insulation testers available. Its LCD offers a combination of digital readout and analogue display, with an analogue pointer response for evaluating circuit charge and discharge characteristics. The instrument housing is in tough ABS.Insulation testing to 1000 MΩ. 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 200 mA down to 0.01 Ω resolution. Automatic discharge of circuit under test . 1 mA 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 25 V. Auto-ranging analogue arc scale shows only the scale in use . Live circuit warning above 25 V, also inhibits insulation & continuity tests above 50 V. Lead resistance compensation on continuity . Hands free continuity testing Auto power-down after 5 min . Complies with IEC 1010-1 safety standard installation Category III, 600 V 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 = 1000V dcMaximum Insulation Resistance Measurement = 999MOhmsDisplay Type = LCDTest Current = 200mABattery Life = 3000 5-Second TestsMinimum Operating Temperature = -10°CMaximum Operating Temperature = +55°CPower Source = Battery"
