Introduction
Thank you very much for purchasing our Digital Indicator F331.
The F331 is a digital indicator for a strain gauge sensor, DIN96×48mm in size.
It is best suited for quality control in production lines, including pressure load control of pressing,
pressurizing, caulking, etc., and torque control of rotating devices.
The USB interface is included as standard, which facilitates introduction into a system that is formed
by using the Specific PC software.
To take full advantage of high performance of F331, thoroughly read this operating manual first before
use and understand the explanations contained herein for correct operating procedures.
Also, carefully store this instruction manual so that it can be referred to at any time.
Safety Precautions
Installation, maintenance and inspection of the F331 should be performed by personnel having
technical knowledge of electricity.
In order to have an F331 Weighing Indicator used safely, notes I 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 F331 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 F331 becomes faulty or malfunctions,
provide a safety circuit outside the F331.
●Before using the F331 as described below, make sure to consult with our sales personnel.
- Use in environments not described in the operation manual.
- Use greatly impacting human lives and assets, such as medical devices, transport devices
entertainment devices, and safety devices.
●Do not disassemble, repair, or modify the F331. Doing so may cause a fire or an electric
shock.
●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 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.
●To take measures against lightning surge, install a lightning surge protector (optionally
available).
●Before applying power, carefully check the wiring, etc.
●Use a power supply voltage and load within the specified and rated ranges.
●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 F331 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.
- Where the temperature changes remarkably or there is a danger of freezing or condensing.
- Outdoors, or where the altitude exceeds 2000m.
- Places exposed to direct sunlight
- Dusty 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.
●Install the F331 as far away from devices generating high frequency, high voltage, large
current, surge, etc., as possible. Also, carry out wiring separately from their power lines. Do
not carry out parallel wiring and common wiring.
●Do not use it, when it is broken down.
●Tighten the screws for the screw type terminal block at the specified torque.
If they are loose, shorts, fire or malfunctions may occur.
Tightening torque: 0.2 to 0.6 N•m
●For sensors, external inputs/outputs and options, use shielded cables.
●For turning on/off the power, be sure to keep intervals of 5 seconds or more.
●After power-on, make sure to warm up the F331 for at least 30 minutes or more before use.
●If the F331 is 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 F331. In the case of heavy contamination, wipe off
the contamination with a cloth after dipping it into a diluted neutral detergent and squeeze
it well, and then wipe with a soft, dry cloth.
●Although packing at factory has been considered as shocks can sufficiently be absorbed,
breakage may result if shocks are applied when the spacers are reused for transportation.
If you send the F331 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.
This sign forewarns the presence of hazards
that could result in personnel injury or property
damage when incorrectly handled.
