The BD-Megger is an analog megohmmeter that gives installers more information than the more common light up/dummy light megohmmeters. The needle will point to the megohm reading - giving you a number you can track and monitor to determine if the loop is shorting to ground. The meter also has a handy battery check feature and standby mode. The meter has a flashing green warning light to alert the operator when it is powered on to help lessen the chance of electric shock.
The BD Loops Megger is a 0-600 AC Volt Meter and Megohmmeter/Insulation Tester. The BD –Megger includes: Batteries, Quick Start Guide, Windowed Carrying Case, Detailed Instructions for Testing Loops, and a Testing Record Booklet.
To obtain a megohm reading simply connect the black lead of the megohmmeter to ground touch the other lead of the megohmmeter to the loop wire. Visit the BDLoops.com ‘Education and More’ section to learn more about how to properly meg a loop.
Are you testing your loops with the right meter?
To properly “meg” a loop you must use a megohmmeter and not a multimeter. Because multimeters have an “ohm” setting many installers falsely believe that a multimeter can be used to “meg a loop”. Here is a quick look at how megohmmeters and multimeters differ:
Multimeters generally measure Continuity, Resistance, and Voltage. (For loops multimeters will check continuity, but will not tell you if the loop is shorting to ground.)
Megohmmeters are Insulation Testers. (Megohmmeters will tell you if the loop wire's insulation has been nicked and is causing a short to ground.)
