Warranty14-day returnsSMG5 is a digital insulation resistance tester designed for diagnosing compressors, motors, and transformers in HVAC/R installations. The instrument applies a 1000 V DC test voltage and measures insulation resistance up to 2000 megohms. What it's used for Checking insulation resistance of HVAC/R compressors Measuring winding-to-ground insulation on motors, compressors, and transformers Diagnosing insulation problems caused by moisture or contamination Service checks where a low-voltage meter is not sufficient to properly assess insulation Key features 1000 V DC test voltage — stresses the insulation during measurement rather than performing a low-voltage resistance check only Range up to 2000 megohms — allows assessment of high insulation resistance in HVAC/R equipment Low output current — per Fieldpiece data, maximum output current is below 1 mA Backlit LCD — makes readings easy in plant rooms and during field service Auto power-off — helps conserve battery life in the field Selected specifications Test voltage 1000 V DC Measurement range up to 2000 megohms Maximum output current < 1 mA Display backlit LCD Power supply 4 × AAA batteries In the box SMG5 insulation resistance tester 2 test leads Ground lead with detachable tip Alligator clip Carrying case 4 × AAA batteries User manual
