Weld Option

Weld techniques perform tests simultaneously on multiple ZRAs (one to five). The above weld techniques as found on the Weld tab in the sequencer are identical to their counter parts in Standard techniques with two exceptions:

1. Areas – Before using any Weld techniques a Weld Set Area technique must be placed somewhere in the sequence list before the weld technique. The Weld Set Area sets the area for subsequent Weld type tests. The area setting on the sequencer page is not used by weld techniques.
2. Oversampling – There is no oversampling option for weld techniques as a result any data collected will be less smooth than if collected by one of the standard techniques.

It is also worth noting that Weld Long Term techniques and Standard Long Term techniques are not interchangeable with each other.

WE2(s) and the Weld Tester

On a Gill 12 Weld tester there are two WE2’s each one performs a different role. A normal Gill 12 instrument has only one WE2 (WE2 on the Gill8/12 connector on a Weld instrument) it is the instrument ground and is used to take galvanic measurements.

On a weld tester there is also a WE2 on the Weld connector this is ZRA 2’s equivalent of ZRA 1’s WE1.
