INTRODUCTION

▲Before Using▼

We would like to express our thanks to you for your purchase of our product strain amplifiers

Models 5683/5684.Please read this manual carefully before operating this instrument.

This manual provides the information necessary to operate the instrument safely. This

manual covers basic functions and operations of Models 5683/5684amplifiers and

handling precautions. Place this manual within reach of Models 5683/5684amplifiers. If

you encounter any problems in the manuals, please contact our sales representative.

▲Examining Contents in Package▼

If opening the package in a warm room during the cold season, open the package after it has

reached room temperature to avoid any operational failure due to condensation on the

surface of the product.

The warranty does not apply for the case where damages or faults caused by use against

instructions, warnings, or cautions.

This instrument is delivered after a thorough examination at the factory prior to shipment.

However, please examine the product's condition and verify that no obvious shipping

damage has occurred after opening the package. Also, examine the specifications of the

input units and accessories. If there are any missing or damaged items, please contact our

sales representative.

PRECAUTIONS



To avoid accidents, read this manual carefully before use. Observe the following warning

and cautions when using amplifiers. The warranty does not apply any damage caused

by the use against instructions, warnings, and cautions. To safely use the amplifiers, the

following statements are used in this manual to call the readers' attention.

This indicates a condition or practice that could result in personal injury or loss of life, or may

result in light injury or physical damage if this equipment is misused due to neglect of a

Warning

This indicates a condition or practice that could result in light injury or damage to the

equipment or other property if this equipment is misused due to neglect of a Caution.

In order to avoid electrical shock or burning, confirm that no common mode voltage or

signal is applied to the signal wire when the signal wire is connected

•Power Supply

Make sure that the power supply is within the rating. If any voltage exceeding the rated voltage

were supplied, there would be risk of damage to this amplifier, or even a fire. Also, in order to

prevent electric shock and hazards such as a fire, be sure to use only the AC power cable and the

adapter (3-prong/2-prong converter) supplied with this amplifier.

•Protective Grounding

Be sure to ground this amplifier before supplying power. Grounding is necessary to use this

amplifier safely, as well as to protect the user and peripheral equipment from injury or damage.

Be sure to observe the following instructions:

1) Protective grounding

This product uses a 3-pole power cable, which has grounding. Always connect to the power

outlet having grounding. If using 3-prong/2-prong adapter, secure the grounding by connecting

either a protective terminal or a grounding lead extending from the adapter.

2) Caution on protective function

While the power is supplied to the amplifier, do not cut or remove the protective grounding line.

Otherwise, safety of the amplifier is not guaranteed.

3) Protective function failure

Avoid using this product when there is a failure in protective grounding or protective functions.

Confirm that there is no failure in the protective function before using.

•Use in Gaseous Atmosphere

Never use this amplifier in a flammable or explosive atmosphere, or atmosphere of steam. Use

in such atmosphere will result in danger to users and the amplifier.

•Disassembling the Frame

It is dangerous to remove the frame. Do not remove the frame from the amplifier other than

100VAC/200VAC switching using the selection switch.

•Input Signal Connection

Connect the signal wire to the input terminal after connecting protective grounding terminal to

the ground. When connecting the signal wire, check whether the signal wire is being properly

protected from leak signals from the environment or common-mode voltage in order to avoid

electrical shock or burning.

•Cautions during Operation

Be careful of operations because large voltage might be applied between the input terminal (input

signal wire) and ground of this amplifier or input terminal and output terminal (output signal wire).

•Installation Category and Contamination Level

Models 5683/5684 amplifiers are devices with Installation Category II and Contamination

Level II. Use them following the regulations defined in Installation Category II and

Contamination Level II.

•Caution in Handling

When using this amplifier, always follow the precautions below.

1) Users

Users who are not familiar with the operation of this recorder should avoid using it.

2) Use and storage environment

The storage temperature and humidity of the input units is –20 to 70°C and 10 to 90%,

respectively. Avoid storing in places where the temperature could rise over the storage

temperature and where there is direct sunlight exposure such as inside an automobile.

Do not use this recorder at the following locations.

1. Locations where the temperature and humidity rise due to direct sunlight or heaters. (The

operating environment of the amplifier; temperature: -10 to 50 °C, humidity: 20 to 85%)

2. Wet locations

3. Locations where salt, oil, or corrosive gases exist

4. Damp or dusty locations

5. Locations subject to strong vibrations

3) Cautions on power supply

1. Be careful of power voltage fluctuations. Do not use the amplifier when these are likely to

exceed the rated voltage.

2. If the power supply includes a lot of noise or high-voltage inductive noise, use noise filters

to avoid operation errors.

4) Calibration

We recommend a periodical calibration to maintain the accuracy. More reliable

measurements are possible by calibrating the amplifier once a year (extra cost option).

CAUTION

５

CAUTIONINHANDLING



Read this manual carefully before using the amplifier.

1. Do not apply neither voltage nor current to the output terminal of this amplifier from external

source.

2. Use this amplifier with power supply voltages from 85 VAC to 132 VAC, 180 VAC to 264 VAC,

or 10 VDC to 30 VDC. The AC power supply selection switch is provided inside the chassis. To

switch the AC power supply voltage, refer to page 7-4. If the power fuse is burnt, check the

cause of fuse blow-out. To replace the fuse, always disconnect the power plug and input/output

signal cable first, and then replace the fuse in the fuse holder. For how to replace fuse, see

page 7-3. When replacing, examine the ratings of fuse (e.g. for AC or DC).

3. The operation temperature and humidity of the input units is –10 to 50°C and 20 to 85%,

respectively. If opening the package in a warm room during the cold season, open the

package after it has reached room temperature to avoid any operational failure due to

condensation on the surface of the product.

Do not use this instrument at the following locations.

- High-humidity locations

- Locations with direct sunlight exposure

- In the vicinity of high-temperature heat source

- Location with vibrations

- Locations where salt, water, oil, or corrosive gases exist

４. When using many amplifier units, install fan units.

5. When a case is used to accommodate amplifiers, the case must be grounded.

6. This product uses a flash memory for saving setup values. Replacement of battery is not

needed accordingly.

7. As Models 5683/5684 have AC signal bridge voltage. Amplifier unit whose bridge voltage

frequency differs cannot be used in the same case. In addition, when using several units

closely, always make synchronization. Otherwise, noises may be generated. See 3-8 and 3-9

for details.

8.This amplifier unit uses rotary encoders are used for knobs to control functions. However,

indication position of the knob sometimes stays at the position between scale markings. In such

case, the settings upon power-up may differ from those upon turning off the amplifier. To avoid

such event, it is recommended to allow knob indication to be at the correct scale marking

position.
