SAFETY PRECAUTIONS
The SME series is designed in accordance with “7. SPECIFICATIONS”.
Do not use the SME series in an environment exceeding the specifications. Or, failure of the SME series
may result.
PRIOR TO USE
For safe use of the SME series, do not forget to read the <Safety Precautions> prior to use.
Kyowa Electronic Instruments Co., Ltd. assumes no liability for any damages resulting from user’s failure
to comply with the safety precautions.
SAFETY SYMBOLS
For safety operation of the SME series, the following symbol marks are used in the Instruction Manual.
Improper operation of the system may result in death or severe injury of the
WARNING
1
operator.
Improper operation of the system may result in injury of the operator and
CAUTION physical damage of the system.

WARNING
●Do not short-circuit positive (+) and negative (-) terminals of the dry cell.
Or, it may produce fever or ignite due to a rush current.
●Do not heat or throw into fire.
Or, it may produce fever, ignite or explode.
●Correctly insert dry cells.
●If liquid leaking from the dry cell gets into your eyes, do not rub your eyes.
Wash them well with clean water and consult with a doctor.
●If any liquid from the dry cell comes in contact with your skin, wash quickly with water.
●Do not recharge the alkaline dry cells since the AA size alkaline dry cells are primary dry cells.
●When using the AC adapter with the SME series compatible to the AC adapter, check the power
voltage of the outlet before connecting.
●Avoid using in environment with inflammable gas, etc.
To prevent the risk of fire hazard or explosion, do not use the SME series in environment with
inflammable gas, vapor or dust.
●If any trouble occurs.
To prevent a fire hazard, if smoke is emitted from the SME series, immediately stop using the SME
series.
When using the AC adapter, disconnect the AC adapter from the receptacle.
●Avoid measuring object applied with high voltage.
CAUTION
●Use the SME series in the specified operating temperature range -10 to 50ºC.
Use at temperatures exceeding the specified range may lower the performance and cause trouble.
If use under direct sunlight or in a cold place is inevitable, prepare a sunscreen or take proper measures
to keep it warm.
●Use the SME series in the specified operating humidity range 20 to 85% RH.
Use in a humid place exceeding the specified range or where it is exposed to splashing water may lower
the performance and cause trouble.
●Immediately stop the SME series if operating environment changes abruptly.
Leave the SME series as it is until it becomes adaptable to the environment.
Abrupt change in ambient temperature due to transportation, etc. may cause dew condensation result to
deteriorate its performance and cause trouble.
●Do not use the SME series in strong electromagnetic field.
Use the SME series in a magnetic field environment where the PC may be used.
If the SME series is used near devices generating strong magnetic field such as a telemetry system,
microwave oven, electric furnace, etc., its performance may be lowered and erroneous operation and
trouble may result.
●Do not pull cords and cables.
Lay cords and cables with a certain allowance so that unreasonable force is applied to the connections.
Pulling or applying unreasonable force may cause trouble or interrupt the measurement.

MEMO
NOTE
1. Do not take off the batteries during saving the data.
If the power is forcibly turned OFF during saving the data, recording data may lead to
invalid.
2. Do not use solvent such as thinner for cleaning.
To clean the case, dip a soft cloth to a neutral detergent and twist it tightly.
If the solvent such as thinner is used, the case or panel may melt or be discolored.
3. Do not press on the LCD screen.
Do not puncture the LCD screen by an object with a fine head such as ballpoint pen.
Or, it may cause trouble.
4. Do not insert foreign matters to a SD card slot. Or, it may cause trouble.
5. Do not insert foreign matters or water to a dry cell place.
6. The SME series is not waterproof. After the water is attached, sufficiently clean with a
dry and clean cloth and dry the SME series before using.
7. When not using the SME series for a long time, remove dry cells from the SME series.

1. OUTLINE OF SME SERIES
1-1 OUTLINE OF SME SERIES
The SME series is an indicator that is used with a strain gage or strain gage transducer connected.
Capable of measuring strain easily with the accessory input cable since the SME series incorporates a
bridge box.
Power is supplied by AA size alkaline dry cells (2).
Capable of saving the measured data in a commercially available SD card.
The SME-100A/101A can be used for checking the operation of an optional Network Terminal Box
NTB-100A (hereinafter referred to as the NTB). Furthermore, the SME-100A/101A can also measure up to
33-CH by connecting the multiple NTB units.
An optional AC adapter can be used with the SME-31A/101A.
