External Bridge:

When to use it: It is best to use the large or small bridge on the main unit when possible.

Conditions where you cannot use the bridge sensors and should use the External Bridge are

listed below.

1. Pure gold, pure silver, or silver alloy bars that at least 50 mm (about 2 inches) wide and

12.5 mm (about ½ inch) thick. Potential uses include 100 oz silver bars and most gold

good deliver bars.

2. Cases in which you are concerned about possible thick cladding on these larger bars,

or drilled out areas where other metals are inserted; therefore a thru measurement of

the sample resistivity is needed. Also, the External Bridge's ability to get an electronic

density measure of the bar is needed to augment the resistivity measurement.
