BD Loops Analog Megohmmeter Loop Tester
BDLoops Megohmmeters are the only meter than can test for the most common loop issue - a nick in the insulation causing the loop to short to ground. This is why they are referred to as "Insulation Testers".
This analog megohmmeter gives installers more information than the more common light up megohmmeters. The pin 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 BD Loop Megger includes:
- Quick Start Instructions for Testing Loops
- Indepth Instructions for Testing Loops
- Testing Record Booklet - Track loop performance and protect your installation.
- Carrying Case
To obtain a megohm reading simply connect one lead of the megohmmeter to the loop and connect the other lead of the megohmmeter to ground.
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 as is causing a short to ground.)
