This compact clamp meter provides high resolution current readings up to 80A ac or dc. The backlit 4000 count display permits readings up to 4 digits or 1mA resolution. This provides far greater low current resolution than most traditional clamp meters which are typically designed for electricians rather than electronics use. Simply clamp the jaws around the conductor and the display reads the dc or ac current present. Voltage, resistance, continuity, frequency and diode testing are performed by connecting the included test leads to the banana sockets at the bottom of the unit.
