Operation Manual # 02002215
4.4 PPDT Automatic Timing Switch (P/N 02001505)
The PPDT is required when conducting Procedure B - Automatically Timed Flow Rate
Measurement tests in accordance with Procedure B of ASTM D 1238, ISO 1133, DIN 53735,
JIS K7210 and other similar methods. It is also necessary for volume measurements (MVR).
The PPDT utilizes a precision optical encoder to monitor piston position and operate the timer
in the MP1200 Controller/Timer. The Starting Positions and Piston Travel Distances for up to
ten “time vs. distance” captures can be preprogrammed into the MP1200 Controller/ Timer.
4.5 Automatic Timing Switch Calibrator (P/N 02001531)
NOTE: To use the Switch Calibrator with the MP1200, add Adapter Assembly, P/N:
02002195.
Used for verifying and calibrating the actual piston travel distances measured by the PPDT.
It can also be used to verify and/or calibrate older style Mechanical and Programmable
Actuating Switches and Programmable Piston Displacement Transducers used on older
Model UE, MP987, MP993, MP993a and MP600 Extrusion Plastometers. However, the
instructions in this Manual cover only the verification/calibration of the PPDT on a melt
indexer equipped with a MP1200 Controller/Timer. Contact the factory for instructions for
verification/calibration when using other types of controllers and actuating switch types.
The Calibrator consists of a 0 to 2” barrel-type micrometer head with 0.001” divisions, a
threaded spacer and a mounting bracket. The mounting bracket permits checking the switch
while it is mounted on the machine. A wooden storage box is also included.
NOTE: Digital version available (02001651). Contact factory for details.
4.6 Manual Cutoff Option (P/N: 02002104)
This optional accessory is available on both the MP1200 & MP1200M. It can be used to cut
the extrudate instead of using the cutoff tool. The operator turns a hand crank to cut the
material.
4.7 Automatic Cutoff Option (P/N: 02002105)
This optional accessory is available on both the MP1200 & MP1200M. It can be used to
automatically cut the extrudate instead of using the cutoff tool.
4.8 Weight Support, Lowering and Lifting Device with Swing–Away Weight Support
Platform (WLD)
This accessory is included with the MP1200M. It is used to raise and lower the test weight(s). It
includes an integrated encoder that permits display and control of the height of the weight support
platform. It can be operated manually by buttons on the touchscreen. When performing
Procedure B, C & D tests, it can be programmed to automatically move to a selected height at the
