7. INSPECTING THE CRIMP HEIGHT
Crimp height inspection is performed using a micrometer with a modified anvil, commonly referred to as a
crimp-height comparator. TE Connectivity does not manufacture or market crimp height comparators. Detailed
information on obtaining and using crimp-height comparators can be found in instruction sheet
408-7424 .
1. Refer to Table 1 and select a wire (maximum size) for each crimp section listed.
2. Refer to section 5, CRIMPING, and crimp the contacts accordingly.
3. Using a crimp height comparator, measure the wire barrel crimp height listed in Table 2.

If the crimp height conforms to that shown in the table, the tool is considered dimensionally correct.

If not, adjust the tool. Refer to section 8, ADJUSTING THE RATCHET.
CAUTION
Do not use damaged product. If a damaged contact is evident, replace it. Do not re-terminate contacts.
