Probes
Use these procedures when repairing or replacing defective components in the
current probes.
WARNING.
Probe disassembly must be performed by qualified service personnel.
The probes that mate with the TCPA300 and TCPA400 Current Probe Amplifiers
have two physical styles. The TCP305 and TCP312 use a slender form factor
that contain three replaceable assemblies -- the connector/cable, the circuit board,
and the current transformer.
The TCP303 and TCP404XL use a pistol-style case with an integral handgrip.
These probes contain two replaceable assemblies -- the connector/cable/circuit
board assembly and the current transformer. Both probes use a few mechanical
components that are replaceable, such as springs and plastic parts.
