Measures AC plus DC current. AC and AC plus 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 and 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. 200 and 2000 A AC plus DC measurement. LCD with dual measurements. 6000 counts for current, voltage, resistance, temperature and capacitance. 2000 counts for frequency. 40 to 400 Hz frequency rating. Includes (2) 1.5 V AA batteries, test leads and carrying case. Jaw opening 2.1 inch. Category IV, 1000 V measurement. TSG-3 test leads, TC-30 carrying case replacement part. 600, 6k, 60k, 600k, 6M and 40MOhm resistance measurement. AC plus DC true RMS power. 6, 60, 600, 1000 VAC plus DC voltage measurement.
