ないことを確認してから行ってください。

・ 接続端子は,緩みのないように確実に締め付けてください。
・ 通電中は,入力端子およびその他の端子またはプラグ挿入

口等に触れないでください。

・ 通電中は,ケースおよびカバーを開けないでください。
・ 外付変流器と組み合わせて使用する場合,変流器の 1 次側

に通電されている状態で 2 次側をオープンにすると危険電
圧が発生しますので,計器をはずす前に 2  次側を短絡して
ください。

・ 通電中のレンジ切り替えのためのプラグの差替えは,危険

ですので行わないでください。

The safety symbol 

 is shown both on the instrument and 

throughout the instruction manual to draw attention to the necessary 

safety precautions. 

 WARNING

To avoid injury or death to personnel and damage to the 

instrument, be sure to comply with the following.

•  Make  sure  that  the  source  voltage  is  not  alive  before  you 

attempt to connect the instrument to the circuit. 

• Once you have connected the instrument to the circuit, tighten 

the terminals.

•  Never  touch  the  terminals  of  plug  holes  when  operating  the 

instrument. 

• Never open the case or cover when operating the instrument. 
• In an application where the instrument is used in combination 

with an external current transformer, a hazardous voltage will 
develop if the transformer’s secondary stage is open-circuited 
with the primary stage electrified. Be sure to short-circuit the 
secondary  stage  before  removing  the  instrument  from  the 

transformer.

•  Never  change  the  plug  at  the  terminal  when  operating  the 

instruments.

• Be sure not to exceed the rated current and the rated voltage.
