2000A Industrial Clamp Meter. Measures AC+DC current. AC and AC+DC voltage measurements with selectable digital low pass filter for accurate voltage and frequency readings on variable frequency drives. Also measures DC voltage, resistance, capacitance, temperature and frequency. Tests continuity and diodes. Low impedance AutoCheck™ mode automatically selects AC or DC volts, resistance or continuity. Low impedance masks ghost voltage pickup. Backlight & relative mode for added versatility. Two voltage detection modes - non-contact or using a single test lead. Computer interface capability using optional CMSC-1U cable and software. Data hold. Crest (peak hold) feature captures current or voltage peaks as short as 5 milliseconds. Lifetime Limited Warranty.
