FIELDPIECE Megohm Meter with Leads, Clips & Case



Being a compact standalone meter designed for checking HVACR compressor motor insulation, the Fieldpiece SMG5 provides a 1000 V voltage source, monitors current, and displays the resistance between the test points.

Maximum current output is <1mA and can be used to determine the condition of insulation from winding to ground in a motor, compressor, or transformer.

To test resistance, a DMM supplies low voltage (<1 V) to the test points and is capable of delivering only a few milliamps. It's not a high enough voltage to detect high resistance problems that might indicate moisture and other contaminants and it's not enough current to measure lower values of resistance.

Features and capabilities:

  • Predict compressor failure

  • 1000 VDC stresses insulation to measure up to 2000 Mohms

  • Backlit LCD display

  • Auto-off to extend battery life

  • Case, alligator clip, leads with removable tips


        • Display: 3 1/2 digit liquid crystal display (LCD) with maximum reading of 1999

        • Overrange: (OL) or (-OL) is displayed

        • Low battery indication: The ”Battery Icon” is displayed when the battery voltage drops below the operating level

        • Measurement rate: 2.5 times per second, nominal
        • Operating Environment: 0 to 40 °C at < 70% relative humidity

        • Storage Temperature: -20  to 60 °C, 0 to 80% RH with battery removed from meter

        • Auto power off: approx 15 seconds 

        • Standby consume current: <10μA

        • Battery: 4 1.5 V (AAA size) UM-4 R03

        • Battery Life: 4 hours (continuity) typical with alkaline battery (@20ΜΩ range test 10ΜΩ resistor)
