The guard terminal can be used to minimize the effects of surface leakage and hence erroneous measurements when carrying out insulation resistance tests.

Features Megger BM5200 [1001-289] Insulation Tester

The Megger BM5200 (1001-289) Digital Insulation Resistance Tester is a battery powered instrument with a digital and analog arc display, designed for high voltage insulation resistance testing in the maintenance and servicing of cables, rotating plant machinery, transformers, switchgear and industrial installations.

The BM5200 performs DC insulation tests at 250 V, 500 V, 1000 V, 2500 V and 5000 V. The tester has an insulation resistance measuring range of 100 kiloohms to 1000 gigaohms. Automatic discharge for capacitive circuits under test is provided and decaying voltage displayed. The guard terminal can be used to minimize the effects of surface leakage and hence erroneous measurements when carrying out insulation resistance tests.

The BM5200 Tester offers three insulation resistance (IR) test modes (InS, PI and t) and they are available in any IR test range. In IR mode (InS) tests are initiated by pressing and holding down the TEST button for two seconds and terminated by a second press of the TEST button. A Polarization Index (PI) mode performs a ratio metric test that calculates the ratio of insulation resistance at ten minutes to insulation resistance at one minute. The IR test timer (t) mode facilitates a single fixed time test based on the set time interval t.

For capacitive test objects the BM5200 will automatically discharge through an internal resistor and indicate voltage across the terminals in the range 25 V to 600 V with higher voltages indicated by ‘>600 V’. This feature will give decaying voltage indication following the testing of reactive loads. When the voltage indicator disappears it is safe for the user to disconnect the test leads.

The BM5200 is powered by eight 1.5 V IEC LR6 (AA) cells. Design safety features include high voltage warning indicator, external voltage display after IR test, automatic discharge of reactive loads and test leads.
