3. 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 3 5 SIDE PANEL DIP SWITCH SETTINGS The dip switches are accessed through the opening on the left side of the MPT 250B The access opening
