At geo, we sell a Minim+ with an LED connector and a Minim+ with a CT Connector.
The easiest way to tell what would work best for you, is by looking at the style of your meter. If the meter is of an older design, like the picture on the right and without a digital display / lights, then this will need a CT Clip.
The CT Clip attaches to the live cable coming out of the meter which will then read the current going through the cable to provide a reading.
If your meter has a digital display and flashing lights, then it’s likely that the LED would be best. Simply attach the small sensor to the pulse LED on the front of the meter and that will then provide an accurate reading to the display.
