1. Make sure that all Magtrol Torque Transducers and electronic products are earth-grounded, to
ensure personal safety and proper operation.
2. Securely ground the 6400 Torque Transducer Display case by connecting a good earth ground
at the ground stud located on the rear panel of the unit. Use a number 12AWG, or larger wire.
3. Check line voltage before operating.
4. Make sure that torque transducers and motors under test are equipped with appropriate safety
guards.

1.2 FEATURES OFTHE 6400TORQUETRANSDUCER DISPLAY
Designed specifically for use with Magtrol's In-Line Torque Transducers, the new Model 6400
Torque Transducer Display powers the transducer and utilizes high speed digital signal processing
to display torque, speed, mechanical power and direction of rotation. The 6400 can be used as a
basic display, as an interface with Magtrol TM Software or on the production line. Its features
include:
•High Quality, Easy-to-Read Display: Vacuum fluorescent readout with large digits.
•High-SpeedDataAcquisition: 100 torque and speed readings per second via IEEE (GPIB)
bus.
