PREFACE
Thank you for purchasing an HJ-KCE/HJR-KCE Series electronic balance.
This balance is equipped with a high precision mechanism. It provides parts counting, percentage
weighing, and limit functions helpful in weighing a certain amount, and has various other functions.
This advanced balance employs a user-friendly program, and the key arrangement is also easy to
operate. In addition, the large fluorescent display is eye-friendly, and its high-speed, stable
performance improves your work efficiency.
Because all the models of the HJ-KCE/HJR-KCE series are dust- and water-proof (conforming to
IP65), they can be used in a place exposed to fine dust or to water jets. They can also be washed
in water when they are contaminated.
Check for the following accessories before use.
If you find missing or damaged parts, immediately contact the store where you bought the product
or our Marketing Division.

1 Precautions Relating to Use
This Section “Precautions Relating to Use” sets forth precautionary notes that the user should
observe in order to prevent physical injury to the user and/or damage to property.
The nature of problems that may result in the event of improper operation, and consequential
effects on the quality and performance of the balance, are indicated under the two categories
of “Caution” and “Recommended,” and explained using symbols.
This is a category to indicate improper handling that may
cause physical injury or severe damage to property. Be sure
to follow the directions for safe use to avoid serious
consequences.
This term indicates steps that the user should take to ensure
the quality and reliability of the balance.
Meanings of Symbols Each symbol is accompanied by an instruction.
Do not disassemble or modify the unit.
· Could cause malfunction or heat generation
· Contact our Marketing Division or Technical Service
Division.
Only AC power (rated value) should be used.
Only use the dedicated AC adapter.
· Use of other types of power or adapters may result
in heat generation or malfunction of the balance.
Do not move the balance when a sample is
loaded.
· The loaded sample may fall off the measurement
pan and cause an injury.

Do not place the balance on an unstable base
or use the balance in a location where it may be
subjected to shock.
· The loaded sample may fall off the measurement
pan.
· Accurate measurement may be rendered
impossible.
Do not lay the AC adapter cable on the surface
of the passage.
· Somebody may trip on the cable, causing the
balance to fall off, thereby causing injury and/or
damage to the balance.
Do not use the balance with its adjusters lifted.
· The balance will become unstable, preventing
accurate measurement.
Do not submerge the balance.
· Although the balance is dust- and water-proof, it
cannot withstand high water pressure due to
submergence under water.
Calibrate the balance after installation or
relocation.
· Measurement values may contain errors,
preventing accurate measurement from being
conducted.

Do Not Drop
Do Not Leave

Avoid applying excess force or impact to the
balance.
· Place the sample to be measured on the balance
carefully to prevent breakage or malfunction.
Do not use the balance in a location were it may
be subjected to abrupt changes in ambient
temperature or humidity.
· Accurate measurement may be rendered
impossible.
· Use the balance in an ambient temperature
between 5°C and 35°C and at a relative humidity of
80%RH or lower.
Do not leave the balance overloaded (When it is
overloaded, a series of dots () is
displayed).
· Take down the loaded sample immediately to
prevent breakage or malfunction.
Do not use the balance in a location where it is
subject to direct sunlight.
· The indications would be illegible.
· An internal temperature increase in the balance
may lead to inaccurate measurement.
If the balance is to be unused for an extended
period of time, unplug the adapter.
· This conserves power and prevents deterioration.
Do not use volatile solvents for cleaning.
· The body may be distorted.
· To clean the unit of stains, use a piece of dry cloth
or cloth soaked in a small quantity of neutral
detergent.
Do not use the balance in a location where it
may be subject to air from an air-conditioning
unit.
· Extreme changes in the ambient temperature may
result in inaccurate measurements.
Do not use the balance on a soft floor.
· When loaded with a sample, the balance may tip or
move, preventing accurate measurements from
being conducted.
Do not use the balance when it is tilted.
· When the balance is tilted, an error may be caused,
preventing accurate measurement from being
conducted. Place the balance on a level surface.

(carat) is selected as Unit A, the unit automatically
changes to “g.”
Check changes of the display.
Give the pan a slight press, and check that the
display is changed.
Check that the display goes back to zero when you
lift your hand.
Stand by

Press the On/Off key again.
The balance enters standby mode, and the Stand by
lamp (LED) lights up.
3.2.2 Set a Tare Weight

Weigh additional samples
4 Reset the display to 0.
Press the Zero/Tare key.
The gross weight of the sample on the pan is reset to
0.
5 Put an additional sample on the balance.
The weight of the additional sample is displayed.
In this way, you can add a sample and weigh it by
pressing the Zero/Tare key to reset the displayed
weight to 0.
3.2.2 Display a gross weight
This balance has a function to display a gross weight including a sample and tare. A sample weight
including tare is referred to as a gross weight, and a sample weight excluding tare is referred to as
a net weight. A gross weight can only be displayed when the balance is used as a weighing
machine.
Put tare on the balance to set the tare weight.
Put a sample to weigh on the balance.
The net weight of the sample is displayed.
Press the Function key one time.
The gross weight including the tare weight is
displayed.
The B/G sign is displayed.
When you press the Function key again, the balance
is reset to the normal mode.
Caution:
1. A gross weight can only be displayed when the balance functions as a weighing machine.
2. When a gross weight is displayed, you cannot set a tare range. You can only adjust the zero
point.

Hints 
The following description applies commonly to the weighing machine, parts counting, percentage
weighing, and unit converting functions.
1. A small amount of current is still flowing after the balance is turned off.
In a standby state, the Stand by lamp (LED) is lit. When the balance is turned on, the LED
goes out.
*The LED does not light up when the balance is operated on batteries.
2. The bar graph indicates the current load condition in relation to the weighing capacity. As the
load approaches the weighing capacity, the bar gets closer to the right end.
*When a tare range is set, the weight is reflected in the bar even though the display indicates [○].
3. When the balance is stable, a circle is displayed. When it gets unstable, the sign goes out.
When the balance is affected by wind or vibration, numeric values on the display may flicker or
the sign to indicate that the balance is stable may go out. In that case, improve the stability by
resetting Function 1 (refer to page 14) according to the following table.

If the influence of the wind or vibration is small, set these setting items of Function 1 higher.
Set these items lower as the influence is increased.
4. When you reset the display to 0 or set a tare range, the display indicates 0, and the [®0¬]
sign is displayed. When you set a tare range, the [Net] sign is displayed.
5. When a tare range is set, the weighing capacity is reduced accordingly. Weighting capacity =
original weighing capacity – tare weight
6. A series of dots [] displayed after an object is put on the balance, indicates that the
weighing capacity is exceeded.
7. When you remove the pan, and the zero point falls bellow the original zero point, a series of
dots [] is displayed.
8. When you select the parts counting function or the percentage weighing function, the display
still indicates zero when you press the pan until the weight of a sample is stored.
9. When you turn on the balance, it starts in the mode when it was turned off. For example, if you
turn off the balance in the parts counting mode, it starts in the parts counting mode when it is
turned on the next time.
*
When the zero point deviates from the true zero point
by one fourth of a division, the ®0¬sign goes out
* When you set a tare range, the display indicates
0, and the Net sign is displayed.
