PT740-3A (with BNC connector) Input: AC:0.2-140A,DC:0.4-140A;AC:140-1400A DC:140-1400A Ratio: 1A/10mV,1A/1mV Auto-zero, use BNC connector to input oscilloscope
The PT740-3A is a very professional AC/DC current clamp capable of measuring all AC/DC currents quickly, safely and easily. Using the Hall effect principle of measurement, it is capable of measuring up to 1400 A DC as well as 1400 A AC peak.The PT740-3A is also suitable for power measurements and is capable of measuring RMS values in the presence of DC interference. Perfect for use on oscilloscopes or other instruments with BNC inputs, it is a high precision current clamp with a one mV BNC output. It can be used directly on display oscilloscopes or auto-zeroing systems.
