INSTRUMENT DESCRIPTION
1.1 Introduction
The TEGAM Model R1L-BIR1 bond meter is a purpose built,
rechargeable battery powered portable instrument for ground
bond measurements. The R1L-BIR1 comes with push-pin
probes and Kelvin alligator clips, all housed within a
ruggedized case. It can accurately make measurements with
a resolution of 1
µΩ
. It has 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).
