For good performance, and proper and safe use of the F381A, be sure to read this instruction manual and properly understand the contents of it before use. Also, carefully keep this instruction manual so that it can be referred to at any time.
Page 3 Warning on design ● For the entire system to function safely when the F381A becomes faulty or malfunctions, provide a safety circuit outside the F381A. Warning on installation ● Do not modify the F381A. Doing so may cause fire or electric shocks.
Page 4 - Do not wipe with a wet rag, or with benzine, thinner, alcohol, etc. Doing so may cause discoloration or deformation of the F381A. In the case of heavy contamination, wipe off the contamination with a cloth after dipping it into a diluted neutral detergent and wringing it well, and then wipe with a soft, dry cloth.

1-2. Features The F381A is a Dynamic Force Processor that can display waveforms of physical quantities, such as load, pressure, torque, etc., in combination with a strain gauge type sensor. Changes in physical quantities that are hard to grasp numerically can be grasped visually on waveform display.

When Measurement Waveform Preservation by the Automatic Operation is “On (Overwrite)” and SD memory card is full, present waveform is preserved by overwriting on the oldest file.In this case, it is possible to take about several seconds to write in the waveform.

[In the case of standard, line driver spec] The sensor output pulse count is beyond the F381A internal count range. Set so that the sensor output pulse count will not go beyond the internal count range. Also, input the DPM Positioning signal at an appropriate time because inputting the DPM Positioning signal clears the internal count to zero.
