取扱法および使用上の注意

1.  計器は,直射日光の当たる場所,外部磁界のある場所,振動の

ある場所,あるいは高温高湿な環境では使用しないでください。

2.  計器は,常に水平位置(標準姿勢)で使用してください。
  このとき最も正確な指示が得られます。
3.  多数の計器を並べて使用するときは,でき得る限り離して使う

ようにしてください。

4.  計器の結線に先だち測定範囲,極性等をよく確認し,端子の締

付けあるいはプラグの締付けは確実に行ってください。

  また大電流の測定時には,その接続導線の電流容量にも注意を

はらい十分太い線で行ってください。

5.  測定に入る前に指針が目盛の零位に一致していることを確かめ

ます。もし一致していなければ零位調整器を左右に回して合わ
せます。ミラーに映った指針の像と指針とが一致する目の位置
で行ってください。ただし,指針の曲がりで零位から外れたも
のは,誤差の原因となりますので,零位調整器で合わせないよ
うにしてください。

6.  計器に,その最大目盛値以上の値をみだりに加えないよう注意

してください。測定値があらかじめ予測できない場合には最も
大きい測定範囲から順次下位に換えて測定してください。

7.  測定の精度を高めるために計器の指示はなるべく最大目盛値か

らその 1/2 の間の目盛で読みとれるような測定範囲の計器を選
びます。

8.  測定中に計器の窓ガラスの表面を乾いた布で強く拭きますと静

電気のため指示が変化することがありますので避けてください。
特に乾燥期にはご注意ください。

  表面の汚れは,乾いた柔かい布で軽く拭きとってください。

OPERATING INSTRUCTIONS

1.  Do not use these instruments in a location exposed to direct sunlight, an 

external magnetic field or mechanical vibration or in a high-temperature 

highly humid environment.

2.  Place the instrument on a fairly level surface. 
 

A horizontal position will give the highest accuracy.

3.  When using a number of these instruments in an array, keep them as far 

away from each other as possible.

4.  Before wiring any of these instruments, carefully check the measuring 

ranges and polarities. When wiring, securely fasten the terminals and 
plugs. When a large current needs to be measured, use wire that is both 

thick enough and has sufficient current-carrying capacity.

5.  Before measurement, check that the pointer coincides exactly with the 

zero scale point. If it does not turn the zero adjust screw provided on 
the meter cover until the pointer meets the zero scale point.

 

Position your eye so that the mirror image of the pointer coincides with 
the actual pointer. However, if the pointer is off from the zero scale 
point because the pointer is bent, do not adjust using the zero adjust 
screw because this will lead to errors.

6.  Be careful not to apply an unreasonably large current or high voltage to 

the instrument.

7.  For the optimum instrument accuracy, select a measuring range such 

that the indication may be read in the top half of the scale.

8.  Try not to apply too much force when wiping the glass window surface 

of the instrument during measurement. Doing so may result in a 
deviation in the indication due to static electricity. 

 

This is especially true when the instrument is used in a dry season.

 

If the surface is dirty, gently clean it using a dry, soft cloth.
