INTRODUCTION

The

2038 Portable Precision-pointer Frequency Meter

is a portable

instrument that performs frequency-to-DC current conversion. It does this
by combining a differential transducer with a DC current meter in order to
read frequencies directly. Its indicator uses taut-band suspension, making
it more resistant to vibration and shock and, as a result, far superior to
conventional frequency meters.
