ESM™ Series Digital Multimeters. AC+DC True RMS gives accurate readings on complex waveforms. Low impedanc3e AutoCheck™ mode - automatically selects AC or DC volts, resistance or continuity. Low impedance masks ghost voltage pickup. dBm function with 20 selectable reference impedance values. Crest capture (peak hold) plus recording of max, min, max-min and average. Two voltage detections modes: Non-contact or using a single test lead. Two temperature measurements using type K thermocouples. Conductance measurement. Lifetime limited warranty. Accessories included: (1)9V battery, bead temperature probe, test leads, protective boot, carrying case. Includes Certificate of Calibration.
