Use a megohmmeter to measure insulation resistance in the field (non-destructive, trend monitoring). Use a hipot (dielectric withstand) tester to verify insulation breakdown thresholds in manufacturing or safety tests. Choose based on your use case, voltage needs, and test objectives. (more...)

Common Mistakes When Using a DMM
A DMM is essential—but simple setup errors can produce bad data or create hazards. Always verify lead placement, function/range, and CAT rating for the environment. Follow NFPA 70E safe work practices and select a meter rated for the task. (more...)
Detecting and Measuring High Voltages
Panel meters, digital multimeters (DMMs), power monitors and other general-purpose instruments are typically limited to detecting and measuring voltages less than 1000V. Specialized instrumentation is required for AC or DC voltages above this level. (more...)
Ratemeters Explained
A ratemeter is a measuring instrument that accepts input pulses and displays a value that is proportional to the rate at which the pulses occur, averaged over a time selected by the user. (more...)
Electricity Submetering
Energy submetering involves installing metering devices (kWh meters) downstream from the main utility meter to track energy usage at a more granular level. Submetering is often employed in multi-tenant residential and commercial buildings with a master utility meter. A submeter for each unit allows the energy cost to be allocated based on a tenant’s total consumption and usage pattern. (more...)
