 Description Click here to view full-pdf specification sheets Tests insulation at rated voltage into a 1 mA load 200 mA short circuit continuity current Automatic discharge of circuit under test Visual warning of energized circuits above 25V The Megger BM120 series of Digital Insuklation and Continuity Testers offersd a cost efferctive solution to testing where only basic test facilities are required. Instruments are available with single insulation test voltages of 500 Vd.c. or 1000 Vd.c. and test results are displayed on a clear 3-digit autoranging LCD. Full rated test voltage is produced when supplying up to 1mA load.. Applications The BM120 Series will find applications in domestic and industrial electrical contracting and in site maintenance departments.Both instruments may be used on capacitive circuits since, at the end of an insulation test, the circuit under test will be automatically discharged through 360 k½ internal resistance. The BM120 Series of Insulation and Continuity Testers are ideal for testing transformers, motors, generators, switchgear, domestic appliances, power tools etc. as well as fixed wiring systems. Although low cost, both instruments meet the requirements of most International Standards including VDE0413 Part 1, HD384, IEC364 and BS7671 (the 16th Edition of the IEE Wiring Regulations). This ensures that the rated insulation test voltage can be achieved into a 1 mA load, ie. 500 V into a 500 k½ load or 1000 V into a 1 M½ load. Features • Insulation test ranges produce the rated test voltage into a 1 mA load. Testing can be carried out to International Standards requirements. • Single test voltage avoids accidentally overstressing the insulation of the item under test. • Clear three digit liquid crystal display produces unambiguous test results. • Automatic discharge of capacitive items following an insulation test ensures that circuits are not left dangerously charged. • Continuity range has 0,01 ½ resolution and a short circuit current in excess of 200 mA to meet the requirements of International Standards. • No need to press the test button when continuity testing leaves both hands free. • One button turns instrument on and operates insulation test. • Automatic switch-off after 5 minutes.
