Important Notice
・It should be known that this product contains potential danger. And so
please be sure to observe this document when installing, operating or
servicing this product.
・SHINKO DENSHI CO., LTD. will not take any responsibility for any
injury or damage caused by the non-observance of this document or
misuse or unauthorized modification of this product.
●
Potential dangers are increasing in the industrial equipment industries due to the
advent of new materials and processing methods, and speeding up of machines. It
is impossible to foresee all situations related to these dangers. In addition, there
are so many “impossible” and “don’ts” and so writing all of them in the operation
manual is impossible. Therefore, it is safe to think that what is not written in the
operation manual “cannot be performed” unless the operation manual positively
writes “it is possible.” When performing installation, operation, maintenance or
inspection of this product, not only observe what is written or indicated in this
document or on the product surface but also pay adequate consideration to safety
measures.

1Prior to use
1-1 Precautions
■ No disassembling or modification.
Unless specifically stated in this document, disassembling or modification of this product,
mounting or removal of an undesignated component no longer maintains the function of the
explosion-proof structure, leading to a serious accident or bodily injury.
■ Install the power supply box in“non dangerous location.”
Use of the power supply box in a dangerous place will cause trouble such as an explosion or
a fire.
■ Connect the grounding terminal and cables properly.
Improper connection of the grounding terminal and cables will cause trouble such as an
explosion or a fire.
■ Do not replace fuse, optional slots of the power supply box or access to the
AC power terminal when the AC power cord is connected to the mains power.
That may cause an electric shock, short-circuiting or failure. Make sure disconnect from the
AC mains or shut down theAC mains before accessing to those parts.
■ Do not connect the cables with its connector or jack being wet.
That may cause an electric shock, short-circuiting or failure.
■ Do not wet the power supply box.
That may cause an electric shock, short-circuiting or failure.
■ Do not open the AC connector cover unless the power supply box is
installed as a built-in unit on a distribution board or other enclosure of which
access is permitted to the trained and authorised persons only.
That may cause an electric shock, short-circuiting or failure.
■ Do not move the device with a sample to be weighed set on the scale.
That may cause the sample to fall from the weighing pan, leading to a bodily injury or
destruction of the sample.
■ Do not connect to the main unit the power supply cord, scale cable, or
communication cable with its connector or jack being wet.
That may cause an electric shock, short-circuiting or failure.
■ Do not use the product on an unstable table or a place that is subject to
vibration.
That may cause the article to fall from the weighing pan, leading to a bodily injury or
destruction of the article. Besides inaccurate weighing may result.
■ Do not move the scale holding its windshield.
That may cause the scale itself to fall, leading to a bodily injury or malfunction of the scale
itself. Be sure to hold the main unit of the scale to move it.
■ Do not place an unstable sample on the weighing pan.
The sample may fall down and cauyse injury. Put an unstable sample in a container (tare)
before weighing it.

1Prior to use FZ-Ex series operetion manual
－2－
■ Do not use the product in an abnormal condition.
If it should happen that an abnormal event such as smoking or unusual odor occurs, ask the
store where you purchased the product for repair. Keeping using the product may result in an
electric shock or fire. In addition, do not ever try to repair it for yourself, or very dangerous
situation is likely to occur.
■ Do not touch the electrode with a wet or dirty hand.
Otherwise, an electric shock or short-circuiting may result.
■Avoid miswiring of the barrier.
Erroneous barrier wiring in the power supply box is likely to cause failure.
■Do not give a shock to the scale.
It may cause breakage or failure. Place a sample to be weighed softly.
■Do not let an overload situation (o-Err indication) continue.
It may cause breakage or failure. Remove the sample to be weighed immediately.
■Do not use volatile solvent.
Use of volatile solvent is likely to deform the main unit. Dirt on the main unit should be
removed with a piece of dry cloth or cloth wet with small amount of neutral detergent.
■Do not use the product where wind from an HVAC equipment directly
applies.
Accurate weighing may be impeded due to the fluctuation of surrounding temperature.
■Do not use the product where there is direct sun.
Accurate weighing may be impeded due to the rise of internal temperature.
■Do not use the product where floor is soft.
Accurate weighing may be impeded due to the tilting of the main unit when an object is
placed on it.
■Do not use the product where there is violent fluctuation of surrounding
temperature or humidity.
Accurate weighing may possibly be impeded. Use within a temperature range of 5 to 40 C
and below a humidity of 85% RH.
■Do not use the product on an unstable table or a place that is subject to
vibration.
It may cause not only inaccurate weighing but also the sample to fall from the weighing pan,
leading to a bodily injury.
■Be sure to make adjustment at the time of installation or changing a use
place.
There occurs an error in measurement value. For the sake of accurate measurement, be
sure to make adjustment.
■Check for an error periodically.
Use environment and chronological change cause an error in measured value, leading to an
inaccurate measurement.
■Align the level of the scale without fail before use.
Weighing with a slanted scale causes an error, leading to an inaccurate measurement. Put
the scale on a robust place.

Check the top of the weighing pan.
Make sure that nothing is placed on the top
of the weighing pan.
2
Make a zero adjustment.
Push the [Zero] key.
Displays on the main LCD become zero and the
symbol “ ” lights.
(1)
It might be possible that the “Zero adjustment” cannot not be performed when an object
is placed on the weighing pan. In that case, make the “tare weight subtraction” referring
to the “Weighing an object placed on a container (tare)”
(2)
Stability waiting during the zero adjustment can be set using the function item “Stability
waiting.” In the case the “Stability waiting” is set, the symbol “M” flashes during the
stability waiting. For its setting method, refer to “3 Functions related to the operation.”
(1)

2-3 Weighing an object placed on a container (tare)
When weighing an object to be weighed with the object placed on a container (tare), the
weight of the container must be subtracted from the total weight to get the actual weight of the
object to be weighed. This is called “tare weight subtraction.”
1
Place a container on the weighing pan.
The weight of the container is displayed.
2
Perform the tare weight subtraction.
Push the [Tare] key.
The indication changes to zero and the “Net”
symbol lights.
The indication changes to zero and the
“ ” symbol lights.
3
Place an object to be weighed on the
container.
The net weight of the object to be weighed
alone is indicated.
4
Clear the tare weight.
or
Remove the tare and the object to be weighed
from the weighing pan.
［Push the [Zero] key or the [Tare ] key.
The indication changes to zero and
the“ ” symbol goes out.
(1)
Performing the tare weight subtraction narrows the weighing range as much as the amount
of the tare weight mass (tare weight).
Weighable range = weighing capacity - tare weight
(2)
Stability waiting during the tare weight subtraction can be set using the function item
“Stability waiting.” In the case the “Stability waiting” is set, the symbol “M” flashes during the
stability waiting. For its setting method, refer to “3 Functions related to the operation”.
(3)
When using a tare whose tare weight is already known, the tare weight subtraction can be
performed in advance by inputting its tare weight (preset tare weight subtraction). For its
setting method, refer to “5 User information setting”.
(4)
When turning on the power placing a tare that exceeds the zero adjustment range at the
time of power supply, the tare weight subtraction is executed.
(1)
Operation of the above (4) is not performed.
