Calibrate the crimp micrometer
Before delivery, each machine is calibrated and should be ready for use upon receipt. However, machine
calibration should be checked on a monthly basis and when gauge settings consistently produce
diameters away from that required in the crimp specification. Calibration procedure is as follows:
To calibrate using Megacrimp coupling (8G)
1. Place die set (D 33) in the machine.
2. Set the gauge setting mechanism to 2.00.
3. Crimp the megacrimp coupling.
4. Measure the crimped diameter of the shell — it should read 26.0.
5. If the crimp diameter is as specified, the machine is correctly calibrated.
6. If the crimp diameter is outside the stated dimensions, it is necessary to recalibrate the machine
as follows:
i. Isolate the machine from power supply.
ii. Note by how much the measured crimp diameter differs from the required 26.0
mm calibration diameter.
iii. Remove
cover.
iv. Calibration adjustment is now via the Contactscrew and Counternut 1.6 of screw
clockwise (when viewed from the screw end) will
reduce
the crimp diameter by 1
mm. Turning the Contactscrew anti-clockwise
increases
the crimp diameter 1
mm. One full turn of the Contactscrew equals a difference in crimp diameter of
0.64 mm.
v. Unlock the Counternut and turn the Contactscrew the required amount according
to the difference between the achieved and the required crimp diameter.
vi. Lock the Counternut and, tightening the Contactscrew.
vii. Crimp a new calibration shell 8G (use the same type as before) and check that
the correct crimp diameter has now been achieved.
viii. If the required crimp diameter is not achieved, repeat the recalibration process.
