AC/DC Current Probe CA-600A
The 600-ampere current clamp is ideal for use with CarScope i-Tester for performing relative compression tests.
The current clamp can measure up to 600 A (AC or DC). In use there is no need to break into the circuit or disturb the isolation as the opening jaws simply clamp around the current-carrying conductor. No electrical contact is required.

2 to 600 A dc or ac peak |
Rated Output |
0 to 600mV (AC and DC) for 0 to 600A |
Output |
Coil cable with 4 mm banana plug |
