Product Highlights Small size doesn't mean small features. The Amprobe AMP-25 Mini-Clamp is pocket-sized, enabling quick and easy spot checks of electrical systems. With its rugged construction and CAT III 600 V rating, the AMP-25 is a must-have professional troubleshooting tool for commercial electricians and electrical contractors. The AMP-25 is designed to measure AC/DC load current and inrush current for motors. Essential features like True-RMS, non-contact voltage and low pass filter make this clamp stand tall next to clamps twice its size. With the AMP-25, you never have to sacrifice performance for size. Features Features True-RMS sensing for accurate voltage measurements in noisy electrical environments Measures AC/DC current to 300 A (10mA resolution) Includes a low pass filter to accurately measure voltage and current on variable frequency drives Inrush current for motor start-up monitoring Non-contact voltage detection (NCV) for detecting presence of voltage Jaw opening to 1 in (25 mm) Autoranging DCA zero and data hold Maximizes battery life with auto power off Backlit display for easy measurement viewing in bright and dim environment Specifications Feature AMP-25 Best Accuracy AC Current(1) 60.00 / 300.0 A +/-(1.5% + 5 LSD) @ 50 to 100 Hz ≥ 3 A +/-(2.5% + 5 LSD) @ 100 to 400 Hz ≥ 3 A DC Current(2) 60.00 / 300.0 A +/-(1.5% + 5 LSD) @ 300 A range Low Pass Filter 300.0 A +/-(3.5% + 5 LSD) @ 50 to 60 Hz ≥ 3 A True-RMS "¢ Inrush Current "¢ Non-Contact Voltage "¢ Data Hold "¢ (1)Note: Crest Factor (C.F.) may be up to 3.0 as 4000 counts.
