Product Description:
space The MN261 is a high sensitivity probe with voltage outputs (100mV/A and 10mV/A) and combine two switch-selectable ranges of 20A and 200A, thus permitting accurate measurements at low and high levels. The MN261 is designed for oscilloscopes and other BNC terminated instruments. It has two performing ranges (20A, 200A) both voltage output (100mV/A and 10mV/A) and 40Hz to 10kHz response.
