Proceed as follows:
1. Select a contact and a wire (maximum size) for each crimp section listed in the appropriate table at
http://tooling.te.com/data.asp
2. Refer to Section 3; CRIMPING PROCEDURE, and crimp the contact(s).
3. Using a crimp height comparator, measure wire barrel crimp height as shown in Figure 4. If the crimp
height conforms to that marked on the tool, the tool is considered dimensionally correct. If not, return
the tool to TE for evaluation and repair (refer to Section 5; REPLACEMENT and REPAIR).

CERTI-CRIMP Ratchet Control Inspection
The CERTI-CRIMP ratchet control feature on these hand tools should be checked to ensure that the ratchet
does not release prematurely, allowing the crimping dies to open before they have fully bottomed. Obtain a
0.025 mm [.001 in.] shim that is suitable for checking the clearance between the bottoming surfaces of the
crimping dies. Proceed as follows:
1. Select the maximum size wire and strip it according to dimensions listed in the drawing shipped with
the tool.
2. Select contact and crimp section corresponding to the selected wire size (refer to the drawing shipped
with the tool).
3. Position the contact and wire in the crimping dies, as described in Section 3: CRIMPING
PROCEDURE.
4. Hold the wire in place and squeeze the handles until the CERTI-CRIMP ratchet control releases. Hold
the handles in this position, maintaining just enough tension to keep the dies closed.
5. Check the clearance between the bottoming surfaces of the wire crimper and the wire anvil (see
Figure 1). If the clearance is 0.025 mm [.001 in.] or less (on at least two of the bottoming surfaces),
the ratchet is satisfactory. If clearance exceeds 0.025 mm [.001 in.], the ratchet is out of adjustment
and must be repaired. See Section 5; REPLACEMENT and REPAIR.
NOTE
The insulation crimper does not bottom on the insulation anvil.
