This unit conforms to CE requirements. For declaration of
conformity please contact DMC. See following picture for
representative data plate found on the back of each tool.
1. SAFETY
The MPT-250B Wire Crimp Pull Tester is a force
measurement device, and as such should be operated with
due caution. Operators should wear safety glasses for eye
protection because the crimp under test may break suddenly
and fragments may fly off.
Do not overload: The gear motor in the pull tester can
exceed the load limits of the load cell component in this
device. For your protection the MPT-250B has been factory
set to stop if the peak force exceeds 250lb. The unit is set to
automatically stop at readings above 249.9lb.
If the tool becomes inoperable or jammed for any reason,
press the STOP button, then the RESET button to try to
unload the specimen being tested. If this does not correct
the problem, STOP the tool, turn the POWER switch OFF,
unplug the tool and contact DMC.
Intended usage: The MPT-250B is intended to be used to
measure tensile strength of crimped connections from
28AWG to 10AWG wire sizes. It is not intended to be used to
tensile test material coupons, cables, or welded connections.
Typical Workstation: The MPT-250B is typically placed on
a well-lit and sturdy bench with sufficient space around all
sides. It is typically placed at a level so that an operator can
be seated in front of it and comfortably use the tool.

2. SETUP
The Alphatron MPT-250B is shipped from the factory pre-calibrated and tested. To assure consistent, correct results, users
should familiarize themselves with the setup and operation of the unit before placing it in service.
To operate, set the MPT-250B on a flat, level surface in an upright position. The unit can be tilted with the adjustable front feet
to ease operator viewing of the display. Do not handle, pick up or move the unit by exerting leverage against any front or rear
panel controls, fixtures or connections. Always lift by the base plate, preferably at the mid-point along either side. DO NOT use
the lower grip as a handle for lifting or moving the MPT-250B. This can result in permanent damage to the load cell sensing
unit.

3. ASSEMBLY
3.1 UPPER GRIP
The MPT-250B is shipped with the upper grip installed.
3.2 LOWER GRIP
The MPT-250B is shipped with the standard lower grip installed. If an optional lower grip was ordered it will be
necessary for the purchaser to install it.
3.2.1 Self-tightening cam type lower grip (optional)
To install the self tightening cam type lower grip proceed as follows:
A. Remove the screw holding the standard lower grip in place.
B. Place the screw in the mounting hole of the self-tightening cam type lower grip. To get the screw head past
the operating gears into its recess, use the operating lever to rotate the cams into the fully open position.
C. Screw the assembly firmly into place in the load cell sensing unit.

3.2.2 Ring Terminal Lower Grip (Optional)
If the ring terminal lower grip has been ordered, installation is as follows:
A. Remove the screw holding the standard lower grip in place.
B. Substitute the optional grip for the standard grip and tighten the screw until the lower grip rotates with
resistance but is not loose or does not need to be forced to turn.
3.3 FRONT PANEL CONTROLS
3.3.1 MOTOR CONTROLS
NOTE: PRESS AND HOLD SWITCHES FOR APPROXIMATELY 1 SECOND TO ALLOW FOR PROPER ACTIVATION.
START Motor start switch to begin test.
RESET Resets display meter to zero, and resets pull wheel to START position for the next test. RESET must be
performed after each test.
STOP Stops the motor and the meter retains the current peak value.
3.3.2 RATE OF PULL CONTROLS
LO-HI SWITCH
LO (Green) selects rate of pull of 1-5 in/min.
HI (Yellow) selects rate of pull of 6-10 in/min.
NUMBERED RATE SWITCHES
Select the rate of pull, 1-5 in/min (LO-Green), or 6-10 in/min (HI-Yellow) as chosen by setting of LO-HI switch.
3.3.3 DISPLAY CONTROLS
ZERO Adjusts the display to true zero. When turned counterclockwise the meter reading will decrease. When
turned clockwise the meter reading will increase. The display will be checked for zero adjustments at startup and
after each test when the RESET switch is pressed.
RESET Resets the display (clears peak values) to zero.
3.4 OPTIONAL CONTROLS ON THE FRONT PANEL
3.4.1 SETPOINT The SETPOINT option enables an operator to set the force at which the MPT-250B is to stop
automatically if the test proceeds to that force and the connection under test does not fail.
When the SETPOINT/MEASURE switch is held in the MEASURE position it enables the operator to select the set
point by turning the SET adjusting knob next to the switch. As the knob is turned, the set point force will be
indicated on the display meter. Clockwise adjustment increases the set point value, and turning the knob
counterclockwise decreases the value. The force reading from the load cell is disabled, and will not be enabled
until the switch is in the SETPOINT (raised) position. Tests are conducted with the switch in the raised position.
When the load reaches the set point level, the motor will stop and the unit can be reset and reloaded for the next
test.
NOTE: The unit must be turned off, and then back on for the set point measure changes to take
effect.
This option can be used in conjunction with the AUTO STOP (section 3.5.1) feature. When both features are
turned on, the test will stop automatically if either condition is met (AUTO STOP, or SETPOINT).
If the peak reading of the force necessary to part a connection is desired, the set point should be at 249.9lb
before testing.
