SAFETY PRECAUTIONS

The following safety precautions should be observed prior to using 

this product and any associated accessories. Although devices and 

accessories would normally be used with non-hazardous voltages, 

there are situations where hazardous conditions may be present.

This product is intended for use by qualified personnel who 

recognize shock hazards and are familiar with the safety precautions 

required to avoid possible injury. Read and follow all installation, 

operation, and maintenance instructions carefully before   g the 

product. Refer to the manual for complete product specifications.
If the product is used in a manner not specified, the 

protection provided by the product may be impaired.
Inspect the Smart Tweezers case before using.  

Do not use the device if it appears to be damaged.
•  Do not use the device if it operates abnormally. 
•  Do not attempt to measure any components in-

circuit when your circuit is alive or active. 

To avoid possible damage to Smart Tweezers or to the 

equipment under test, follow these guidelines:

•  Disconnect circuit power supply and discharge all high-voltage 

capacitors before testing resistance, inductance, or capacitance. 

•  Do not apply external voltages of more than 1.6 V.
•  Use proper terminals and functions for your measurements. 
•  Only supplied charger (DC 5V) should be used to charge the battery.

SAFETY SYMBOLS AND TERMS

The WARNING heading in this manual indicates 

dangers that might result in personal injury or death. 

Always read the associated information very carefully 

before performing the indicated procedure.
The CAUTION heading in the manual indicates hazards that could 

damage the device. Such damage may invalidate the warranty.
