Calibration
The calibration procedure below will calibrate the Aeroquip
ProCrimp 1390 crimp machine to the original factory set-
ting. While new machines are calibrated at the factory and
will be ready to use upon receipt, this procedure should be
followed if the crimp machine has been disassembled or
has had components replaced. The procedure requires the
use of an FT1307-200-M180 die cage, a 1SB4 socket (or
TTC-4 fitting), and a 1SB8 socket (or a TTC-8 fitting).
NOTE: While in the calibration mode, follow the instructions
precisely, and press the keys deliberately. If a mistake is
made, the calibration procedure must be started over by
turning the machine off and then on again.
1. Insert an FT1307-200-M180 die cage.
2. Press the STORE and ENTER buttons simultaneously, and
then release. Both button lights will now illuminate and will
remain lit until the calibration procedure is finished.
3. Input the value of “210” using the keypad.
4. Center a 1SB4 socket or TTC-4 fitting (without a hose)
in the die cage, holding the socket or fitting in place with
a pencil or other suitable tool. Crimp the socket by
pressing the crimp switch or footswitch until the ma-
chine retracts by itself, indicating a completed cycle.
Allow the die cage to retract to the “full retract” position.
5. Using a micrometer, measure the crimp diameter. The
preferred method is to use the average of the four pairs
of indentations.
6. Locate the crimp diameter in Table A, below. Using the
keypad, enter in the three-digit DISPLAY reading that
corresponds to the crimp diameter.
NOTE: If your crimp diameter falls between the numbers
shown in Table A, simply determine or interpolate the DISPLAY
reading, since the numbers are a direct ratio.
7. Input in the value of “610” using the keypad.
8. Center a 1SB8 socket or TTC-8 fitting (without a hose)
in the die cage, holding the socket or fitting in place with
a pencil or other suitable tool. Crimp the socket by
pressing the crimp switch or footswitch until the ma-
chine retracts by itself, indicating a completed cycle.
Allow the die cage to retract to the full retract position.
9. Repeat steps 5 and 6 at left, using Table B for the -8 socket.
10. After the three-digit DISPLAY reading in Step 9 is entered,
the machine will automatically exit the calibration mode.

Calibration Example:
Crimp a 1SB4 socket, and measure the four crimp
diameters around the socket. Let's say, for example,
that the diameters measure .692, .693, .694 and .694
inches. To obtain the average diameter, add the four
diameters, and divide that sum total by 4.
(.692+.693+.694+.694) =2.773 = 0.69325 = 0.693

(round to nearest
thousandth)
Look at the crimp diameter column in Table A and
find your average diameter. If it falls between two
numbers, as this one does, interpolate the desired
setting. In this case, you would enter 193. If your
crimp diameter is .690, you would enter 190; if it is
.697, you would enter 197.
Crimp a 1SB8 socket, and measure the four crimp
diameters around the socket. This time, let's say that
the diameters measure 1.113, 1.115, 1.114 and 1.115
inches. Obtain the average diameter by adding the
four diameters and dividing that sum total by 4.
(1.113+1.115+1.114+1.115) =4.457 = 1.11425 = 1.114
44
(round to nearest
thousandth)
Look at the crimp diameter column in Table B and
find your average diameter. If it falls between two
numbers, as this one does, interpolate the desired
setting. In this case, you would enter 614. If your
crimp diameter is 1.110, you would enter 610; if it is
1.119, you would enter 619.
