The MA1500 is a 1500A TRMS AC/DC clamp meter. 52mm (2.0") jaw size for conductors up to 500M circ. mils with true RMS for accurate measurements of non-sinusoidal waveforms. Additional features include: Relative mode for capacitance zero and offset adjustment, data hold, peak hold, MIN/MAX, auto power off and inrush function for capturing transients during motor start-up. Complete with test leads, beaded wire temperature probe type K, 9V battery and carrying case.
