Diagnosing Heating Systems With Ohmmeters
An ohmmeter is a device that measures electrical resistance. It may do so using a micro-ohmmeter for low resistance or a megohmmeter (or Megger) for greater resistances. By accurately measuring ohms, some common heating system issues can be identified. Ohms Ohms are the unit of measurement an ohmmeter uses. Named for German physicist Georg Ohm, […]
