4.3.2
Depress the operating lever of the self tightening cam type upper grip to open far enough to accept the test
sample (wire). When you release the lever, the cam wheel will grip the wire.
4.4
SAMPLE OPERATION
The following is an example procedure for testing a wire specimen after the unit has successfully completed the
STARTUP SEQUENCE (section 4.1.4):
4.4.1
Place the terminal end of the wire sample in the Lower Grip (section 4.2).
4.4.2
Pull the sample to remove any slack in the wire and place the opposite end of the wire sample in the Upper Grip
(section 4.3).
4.4.3
Once the sample is taut between the grips, press the motor control START switch (section 3.3.1).
The pull wheel will turn in a clockwise motion thereby tightening the grip on the sample and applying tension to
the wire.
4.4.4
The unit will cease operation once the sample has failed (section 3.5.1) or the force limit has been reached.
Record the value indicated on the display panel.
4.4.5
Press the motor control RESET switch (section 3.3.1) to return the pull wheel to the start position to allow for
the next test.
4.4.6
Press the display control RESET switch (section 3.3.3) to return the display to zero.
4.4.7
Repeat steps 4.4.1 to 4.4.6.
5. CALIBRATION
The MPT-250B wire crimp pull tester is factory calibrated with equipment traceable to the NIST. It is recommended practice
to return the unit to DMC for calibration. In order to maintain traceability to NIST, do not exceed 12 months between
factory calibration intervals. The internal calibration test sequence is a reliable verification that the tester is accurate, but it
does not assure traceability to NIST.
6. TRANSPORT
It is recommended that the MPT-250B wire crimp pull tester be transported within a sufficiently sturdy box to handle the
weight of the tester and that the tester be surrounded with impact absorbing material (i.e. foam) on ALL sides in the box.
It is recommended that any accessories (i.e. grips) being transported with the tester be individually packed and wrapped in
foam to avoid damage.
7. PREVENTATIVE MAINTENANCE/ADJUSTMENT
It is recommended that the MPT-250B wire crimp pull tester be kept clean and free of debris on a daily basis using a dry
cloth.
CALIBRATION ADJUSTMENT OR MAINTENANCE IS TO BE DONE ONLY BY A CERTIFIED OPERATOR OR DMC.
No adjustment or maintenance is to be performed by end users if not certified/trained by DMC.
