Introduction
Thank you very much for purchasing our Dynamic Force Processor F381A.
The F381A is the indicator that measures pressure, load, torque, etc. Being equipped with the waveform
comparison and hold functions, the F381A can be used for multipurposes, such as in automatic assembling
machines, testing machines, etc.
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.
Safety Precautions
In order to have an F381A Digital Indicator used safely, notes we would like you to surely follow divide
into " " and " ", and are indicated by the following documents. Notes indicated
here are the serious contents related to safely. Please use F381A after understanding the contents well.
For safety reasons, please read the following safety precautions thoroughly.
WARNING
This sign forewarns the presence of hazards that could result in serious injury or
fatality when incorrectly handled.

WARNING
●For the entire system to function safely when the F381A becomes faulty or malfunctions,
provide a safety circuit outside the F381A.
●Do not modify the F381A. Doing so may cause fire or electric shocks.
●Do not install in the following environments.
- Places containing corrosive gas or flammable gas.
- Where the product may be splashed with water, oil or chemicals.
●Do not connect a commercial power source directly to the signal input/output terminals.
●Be sure to ground the protective ground terminal.
●Before performing the following, make sure that no power is applied.
- Attachment/detachment of connectors of options, etc.
- Wiring/connection of cables to the power input terminals.
- Wiring/connection of cables to the signal input/output terminals.
- Connection to the ground terminal.
●For connection to the signal input/output terminals, check the signal names and pin
assignment numbers, and then carry out wiring properly.
●Be sure to install the attached terminal block cover after wiring to the power input terminals.
Otherwise, electric shocks may result.
●Before applying power, carefully check the wiring, etc.
●Use at a proper power supply voltage.
●Do not damage the power cord. Doing so may cause fire or electric shocks.
●Do not touch any signal input/output terminal while applying power. Doing so may cause
electric shocks or malfunctions.
●If the cover of the main body is opened, it may cause an electric shock internally. Even if the
power is off, the internal capacitor is charged. Contact us for internal inspection or repair.
●In the case of smoke, an abnormal smell or strange sound, immediately turn off the power,
and disconnect the power cable.
This sign forewarns the presence of hazards
that could result in serious injury or fatality
when incorrectly handled.

CAUTION
●Use the F381A as it is incorporated in a control panel, etc.
●Do not install in the following environments.
- Where the temperature/humidity exceeds the range of the specifications.
- Outdoors, or where the altitude exceeds 2000m.
- Places exposed to direct sunlight
- Dusty places
- Poor-ventilated places
- Places containing large quantities of salt or iron powder.
- Where the main body is directly affected by vibrations or shocks.
●Take adequate shielding measures when using at the following locations.
- Near a power line.
- Where a strong electric field or magnetic field is formed.
- Where static electricity, relay noise or the like is generated.
●Tighten the screws for the signal input/output terminals at the specified torque.
If they are loose, shorts, fire or malfunctions may occur.
Tightening torque: 0.5N•m
●For sensors, external inputs/outputs, RS-232C and options, use shielded cables.
●For turning on/off the power, be sure to keep intervals of 5 seconds or more.
●If the F381Ais not used by the specified method, its protective performance may be
impaired.
●Maintenance
- When performing maintenance, disconnect the power.
- 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.
●When the F381A is shipped, spacers made of corrugated cardboard are used as cushioning
materials.
Though it is factory-designed so that shocks can sufficiently be absorbed, breakage may
result if shocks are applied when the spacers are reused for transportation. If you send the
F381A to us for repair, etc., take adequate measures against shocks by using polyurethane
materials, etc., separately.
●If you dispose of the product, handle it as industrial waste.

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.
With the color liquid crystal touch panel display adopted, twists have been provided in many places
by thoroughly paying attention to ease of understanding so that all operations can be performed
without the instruction manual. Also, having a high-speed processing capability of 4,000 times/sec
ready for fine changes in values, and being equipped with the waveform display, HI/LO limit
comparison and other various hold and judgment functions, it can be used for a wide range of
applications, such as in production control systems, automatic equipment, and testing machines.

●Drawing of load-time and load-displacement waveforms
Not only a load-time waveform in connection with a load sensor but also a load-displacement
waveform can be drawn in combination with a load sensor and displacement sensor.
●Compensation for time variance in pressurization by a pressing machine with a
displacement sensor
Use of a displacement sensor prevents the influence of time variation in pressurization by a
pressing machine.
●Measurement waveform control as divided by using the hold function
A measurement waveform can be divided into up to five sections, and the waveform can be
judged on each section by specifying each HI limit, LO limit, and method of judgment.
Each section can be specified by Setting (time or displacement) or external input signal “Hold.”
The method of judgment can be changed by selection under “Use Hold.”
Judgment point(s) can be kept depending on the selection under “Use Hold.”

●Control of the position at the measurement completion
The position of the measurement completion can be judged by using the End Displacement for
the Use Hold.
The End Displacement is different from other hold types, so it judges not based on a wave
starting point but based on an original point of the displacement.
●Entire waveform control by using the waveform comparison function
Comparisons can be made to judge whether or not a measurement waveform is between HI limit
and LO limit waveforms.
●Measurement-waveform-following control by using the relative comparison function
Waveforms fluctuating up and down with each measurement can be relatively compared.
By this function, comparison waveforms are relatively moved according to the load at the
Reference Point of Relative Comparison, which should previously be set by time or
displacement, on a measurement waveform.
* Relative movement can only be made in the Y-axis direction.
●Change of the control reference to the point at which loading is started or the point at
which it is finished
In the case where the X-axis of the waveform represents displacement, the reference for the hold
function and waveform comparison function can be selected from either the measurement start
point or measurement stop point.
For the measurement start point and measurement stop point, set “Front” and “Back,”

Terms used in this manual are explained below.
- Load
Analog and digital values of load sensor input are expressed as load.
- Displacement
Analog and digital values of displacement sensor input are expressed as displacement.
- Waveform comparison
Checking to see if the acquired waveform is between the HI limit and LO limit waveforms having
been prepared in advance is called waveform comparison.
- Hold function
Controlling a measurement waveform by dividing it into up to five sections and specifying the
method of judgment for each section is called the hold function.
Judgment point(s) can be kept depending on the selected method of judgment (“Use Hold”).
- Measurement
Acquiring a waveform from the start until it stops is called measurement.
- Waveform reference
A reference point is required for controlling a measurement waveform. Such a reference point for
controlling a measurement waveform is called the waveform reference. The reference can be the
measurement start point or measurement stop point.
