

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, and

measures and instructions to avoid such conditions.

This indicates a condition or practice that could result in damage to the instrument or other

property and general cautions that users must take into consideration.

CAUTION

３



•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 is provided with 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 amplifiers.

•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. Note that Model 5693 does not have isolation between the input

block and output block.

•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

Model 5693 amplifier is devices with Installation Category II and Contamination Level II. Use

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

５



•Caution in Handling

When using this amplifier, always follow the precautions below.

1) Users

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

2) Use and storage environment

The storage temperature and humidity of this instrument 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. Avoid using the amplifier when the voltage is

likely to exceed the rated voltage.

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

or other noise protection.

4) Calibration

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

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

CAUTION

６

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 operating temperature and humidity of the amplifiers 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. 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.
