BD Loops BD-Megger Analog Megohmmeter Loop Tester

The BD Loops BD-Megger is an analog megohmmeter (insulation tester) for checking inductance loops. It tests at 500 V and reads up to 1000 megohms. It finds the most common loop fault: a nick in the wire insulation that lets the loop short to ground. A multimeter checks continuity but cannot show this fault. The needle points to a megohm value, so you get a number to record and compare over time, not just a pass/fail light. The gauge is color coded: green is good, yellow is questionable, red is bad. The meter also reads 0 to 600 V AC and has a battery check and a power lock for continuous testing. To test, connect one lead to the loop and the other lead to ground. What's Included Insulation tester with test leads Carrying case (4) AA batteries Quick start instructions for testing loops In-depth instructions for testing loops Testing record booklet Before You Order Tests the loop and lead-in insulation. To check the detector, harness, and board connections, use the BD Loops E-Z Detector Checker. Disconnect the loop from the detector before testing. Log readings in the record booklet at install and at each service so a falling reading shows up early.
