About battery
This equipment uses a built-in nickel-metal hydride battery.
One of the characteristics of the nickel-metal hydride battery is self-discharge thatis after the battery has been charged, it will naturally discharge itself over time.
This means that even when the equipment is not used, the battery voltage
continues to drop gradually due to self-discharge and ﬁnally the battery will discharge
completely.
If the battery has discharged completely, the battery will deteriorate and its
charging capacity will decrease or charging itself may be disabled.
In order to prevent such problems, be sure to charge the battery fully after theequipment was purchased.
Also when the equipment is not to be used for a long period of time, be sure to
charge the battery once every 3 months.

Safety Precautions

WARNING

The precautions presented below are very important for safety and must be observed
strictly. The symbols and their meanings are as follows.
Indicates that it is highly possible that the user will

DANGER････ suﬀer serious injury or loss of life or indicates thepossibility of serious consequences depending on
situations due to the structure and characteristics ofthe product if the product is not used properly.

WARNING･･･ Indicates the possibility that the user may suﬀer

serious injury or loss of life if the product is not usedproperly.

Make sure that theobject being measured
will not ﬂy oﬀ.

When performing measurement which
will destroy or cut an object tomeasure, wear equipment to protect
yourself from broken pieces hitting
your eyes or body.

Do not use a damaged
hook or deformed hook.

The hook may be broken or slip out ofyour hand to cause injury. Or theobject being measured may fall tocause serious injury.

Be sure to insert the AC
adapter to thereceptacle fully.

Loose connection may cause a shortcircuit which can result in electric
shock or ﬁre.

CAUTION･･･ Indicates the possibility of minor personal injury if the
product is not used properly.

DANGER
Do not charge the gage
longer than 24 hours.

Do not use an adapter orcable other than the
included AC adapter anddedicated cable forcharging.

Charging will be completed in about 4.5 hours.
Charging longer than 24 hours will cause thebody to become very hot and depending on
situations, may break the incorporated
batteries to cause ﬁre.

The electronic circuit or other parts may bedamaged.
Such a practice may cause ﬁre or electric
shock.

－1－

CAUTION
Do not plug or unplug
the AC adapter with awet hand.

You may suﬀer electric shock.

Do not hold the cord of
the AC adapter to
unplug it.

The cord may be broken to cause
electric shock.

Never disassemble,
repair or modify thegage.

Such a practice may result in
malfunction to cause personal injury.

－2－

CAUTION
Do not apply a force
exceeding the rated
capacity.

The force sensor may be broken.
Application of a larger force may break
the body case or internal components
to cause accidents.

Do not use or store thegage in theenvironment describedon the right side:・An environment where the gage may
be exposed to water.
・An environment where condensation
may occur.
・A dusty environment.
・An environment where the gage may
be exposed to oil or chemicals.

Use the gage within its
working temperature
range (0 to +40℃).

The use of the gage outside theworking temperature range may cause
malfunction. The working humidity
range is 20% to 60% RH.

Make sure thatmounting screws are ofcorrect length.

When mounting the gage, select such
mounting screws that will not enter
the body more than 6 mm. The use ofa screw longer than this may damage
the body case.

Brief Explanation

Setting of the stand control function※For the setting procedure, see page 9.

Concept of the upper limit value and lower limit value+A

1. When the set values of both the upper limit value
and lower limit value are on the plus (tension)side (A, B) in the ﬁgure, A which is larger is theupper limit value and B is the lower limit value.

B

0
C
D
−

2. When the set values of both the upper limit value
and lower limit value are on the minus(compression) side (D, C) in the ﬁgure, D whichis larger in absolute value is the upper limit value
and C is the lower limit value.

3. When the set values of the upper limit value andlower limit value are on the plus side and minusside of zero (B, C), B which is on the plus side is
the upper limit value and C which is on theminus side is the lower limit value regardless of
their values.

※Both of the comparator function and stand control function operate based on this concept.

（Stand control upper limit value action

This setting is useful when Aikoh’s electric test stand compatible with thisgage is used in combination. By setting a desired force value, the test standcan be moved up/down or stopped when the actual force has reached theforce set value to protect the user’s test sample and at the same time,
various tests can be controlled in force. There are four types of setting as
shown below, from which you can select one.

Using analog outputs※For the setting procedure, see page 9.

（Analog output zero adjustment）
An analog voltage is output constantly from the 26-pin connector provided
at the bottom of the body. (Approx. ±2V at the rated capacity)
The output pin numbers are as follows:

Analog output voltage
Rated capacity±2V/F.S.（Rated capacity）

No. 18・・・Analog Out（±2V/F.S.）
NO. 19・・・Analog GND (A.GND)※For outputting a voltage, use the optional cable RZE-OP-2.

The analog voltage is output in proportion to the actual force being applied tothe sensor, regardless of the indicated value.
Accordingly, a voltage proportional to the actual load by the orientation of themeasuring shaft and the mass of the ﬁxture is output. This is not eliminatedwhen the indication is reset to zero, but by adjustment described here, theoutput voltage when zero resetting is performed can be brought close to zero.
※For setting, connect the optional cable RZE-OP-2 to the gage and connect a
digital voltmeter to the signal line corresponding to the analog output pin No.
Then, select this item by the setting procedure presented on page 9. Usingthekey andkey, change the ﬁgure forward or backward to make thevoltage indicated on the digital voltmeter close to 0 mV.
Finally, press the ENT key to store the set value.

Minimizing battery consumption for eﬃcient use

Automatic zero resetting※For the setting procedure, see page 9.

（Auto zero reset function enable/disable setting）
With this setting at ON, when the indicated value is within two digits, it ispossible to automatically apply automatic zero resetting every about 2
seconds.
This function has been set to OFF in the factory.

（ON）Setting ON

Using the external zero resetting functionO
In addition to the ZER key provided on the gage, it is possible to reset the force
value to zero by inputting an external zero reset signal to the 19-pin connector

at the bottom of the gage.

This gage can run for long hours after it has been charged fully once. If thepower is not turned oﬀ by a mistake or no operation is performed for about 5
minutes continuously, the auto power oﬀ function operates to turn oﬀ thepower automatically. This function has been set to ON in the factory, but if yourenvironment of use does not permit the power to be turned oﬀ, set this to OFF.

※When“P”is ﬂashing, only the peak mating value is shown.

・The hook may be broken or slip out of your hand tocause injury. Or the object being measured may
fall to cause serious injury.
・Apply a force to a point where the extension lineof the measuring shaft and the hook cross. If aforce is applied to the tip of the hook, the hookmay be deformed or broken to cause serious
injury.
・The force sensor may be broken. Application of alarger force may break the body case or internal
components to cause accidents.
・The weight of the ﬁxture will be loaded as a force.
Use a ﬁxture the weight of which is less than
10% of the rated capacity of the gage.
・When securing an attachment, do not tighten itwith a tool too strongly. A large load will beapplied to the sensor to break it. After turning on

please contact the dealer from whom you purchased the gage.
※The contents of setting and memory data may be changed to the factory setting anddata by this calibration and therefore, it is requested that prior to sending the gage forrepair or calibration, you keep a record of the data.
