Mrcartool MMT248 Orange Circuit Tester sku-5088089231

The Orange Mrcartool MMT248 Electrical Testing probe, sku-5088089231, UPC 949579810255, is an automotive circuit tester for 6-30V car electrical systems. It draws power from a vehicle battery or cigarette lighter through the included battery clip and lighter adapters, so no separate battery or charging is needed.

Connect the red clamp to the battery's positive terminal and the black clamp to its negative terminal. On connection, the tester beeps and its headlights illuminate the probe tip's test area. It can test resistance, DC, AC, diodes, polarity, continuity and ground, and can recognize polarity and activate components.

Its DC voltage range is 0-65V +1 digit; resistance range is 0-200 KΩ; tone pass-through frequency response is 0Hz to 10Khz; and circuit-breaker rated current is 1-10 Amp. The stated breaker test standard specifies no trip at 100% current, a trip within one hour at 150%, within 3-30 seconds at 200%, and within 0.5-4.0 second at 300%.
