INSTRUMENT DESCRIPTION
INTRODUCTION
1.1 Purpose
The Model R1L-B is a digital Microohmmeter / Bond Tester
with full scale ranges from 2
mΩ to 20
Ω. The resistan
ce
reading is displayed on a 3½ digit liquid crystal display on
the front panel. An over-range condition is indicated as a "1"
followed by three blank digits (the decimal point is also
displayed in its normal position for the range selected).
A rugged version, Model R1L-BR is also available, which is
electronically identical to model R1L-B, but it has a rugged
case as the enclosure rather than an open front panel.
1.2 Performance Characteristics
This is a range-selection instrument, with a rotary 5 range
selector switch.
