⚠ WARNING is reserved for conditions and actions

that can cause serious or fatal Injury.

△ CAUTION is reserved for conditions and actions that can save minor injury or

that can cause minor injury of instrument damage

△ DANGER

● Never make measurement on a circuit in which the electrical potential exceeds AC 300V using MODEL8127 and A600V using MODEL124, 8125 and 8126.

- Do not make measurement when thunder rumbling. If the instrument is in use, stop the measurement immediately and remove the instrument from the safe measured object.

- Do not attempt to make measurement in the presence of flammable gasses. Otherwise, the use of the instrument may cause sparking, which can lead to an explosion.

● The transformer jaws are made of metal tips are not completely insulated. Be especially careful about the possible shorting where the measured object has exposed metal parts.

○ Measurement Category
To ensure safe operation of measuring instruments, IEC 61010 establishes safety standards for various electrical environments, categorized as 0 to CAT IV, and called measurement categories. Higher-numbered categories correspond to electrical environments with greater momentary energy, so a measuring instrument designed for CAT III environments can endure greater momentary energy out of any than one designed for CAT II.
Circuits which are not directly connected to the
mains power supply
case, CAT II : Electrical circuits of equipment connected to an AC
electrical outlet by a power cord.
CAT III: Primary electrical circuits of the equipment instrument connected directly to the distribution panel
CAT IV: The circuit from the service drop to the service entrance, and to the power meter and primary overcurrent protection device (distribution panel).

DANGER

● Never make measurement on a circuit in which the electrical potential exceeds 300V using MODE127 and AC600V using MODEL8124, 8125 and 8126 in order to avoid possible shock hazard.

The transformer jaws are made of metal a are not completely insulated. Be especially careful about the possible shorting where the measured object has exposed metal parts.

CAUTION

● Take sufficient care to avoid shock, vibration of excessive force when handling the instrument. Otherwise, precisely adjusted transformer jaws damaged.

- When transformer jaws do not fully close, close them by force, but make them free to try again. If a foreign substance is stuck tips, remove it.

● When making current measurements, keep the

Otherwise accurate measurements cannot be taken

Otherwise, accurate measurements cannot be taken. Maximum conductor size is as follows. MODEL8124 : 68mm in diameter MODEL8125/ 8126: 40mm in diameter MODEL8127 : 24mm in diameter

- Hold the inserting part (except for the cable) and disconnect the Output connector from the measuring instrument so as not to cause a break in the cord.
