TCPA300/400 Amplifiers and TCP300/400 Series Current Probes Instruction Manual
TCP303 and TCP404XL
The following procedures explain how to disassemble the probe body and
replace the current transformer, the circuit board, and the cable assembly.
WARNING. Probe disassembly must be performed by qualified service personnel.
1. Unlock the probe slide.
2. Place the probe on a flat surface with the screw heads facing up.
3. Using a

inch Allen wrench, remove the eight retaining screws from the
case.
4. While holding the squeeze handle and slide, lift the top part of the probe
body off.
5. Remove the slide.
WARNING. There is a spring in the squeeze handle that can pop out and cause
personal injury unless care is exer cised when disassembling the probe.
6. Lift the cable out of the probe handle and insert a pair of pliers in the handle
as shown in Figure 7--15.
