携帯用直流電流計，電圧計

は，すべてトートバンド支持方

式を採用していますので摩擦がなく再現性がすぐれ，振動や衝撃に
対しても極めて強い特長をもっています。

INTRODUCTION

A taut-band suspension system is used in all YOKOGAWA portable DC 
ammeters & voltmeters. 
This system has no pivot and jewel bearings so these portable instruments 
are friction less and thoroughly resistant to shock and vibration.
