Model CI-6740
High Current Sensor
012-08627A
Introduction
The PASCO CI-6740 High Current Sensor measures
both AC or DC current between 0 and 10 amperes.
The High Current Sensor is ideal for circuits in which
the current exceeds 1 ampere. Instead of a sensing
resistor, the High Current sensor uses a Hall-Effect
chip, which has no internal resistance and therefore
generally eliminates the need to account for sensor
resistance. The sensor includes a 10-amp fuse, which
is replaceable.
With a set of banana plugs or lead inputs, the High
Current Sensor connects directly to a power supply or
to any PASCO circuit board.
Equipment included:
• High Current Sensor (CI-6740)
Typical Applications:
•
Determine the current output from PASCO’s
Hand Crank Generator or a power supply
•
Measure the current through a PASCO coil
