INSTRUMENT DESCRIPTION
INTRODUCTION
1.1 Purpose
The Model RIM-A Megohmmeter is a portable instrument used
to measure high values of resistance. It is enclosed in a
rugged weather-resistant housing designed for severe
industrial and military applications.
The Model RIM-A may be used to measure resistances
between 50 kΩ and 10 GΩ with 50 V test voltage, and
between 1 MΩ and 200 GΩ with 100 V, 250 V, or 500 V test
voltage.
1.2 Performance Characteristics
This is a digital reading instrument with six resistance ranges
and four test voltage ranges.
