INTRODUCTION
The AIGX has a set-point facility. The set-point signal is an open collector transistor output, which is on when the
pressure measured by the gauge is below a preset pressure. The pressure at which the set-point operates can be
adjusted using the set-trip switch on the top of the gauge (
1
, item 3).
The AIGX is fitted with a status LED (Figure 1, item 4) . This LED indicates the operating status of the gauge.
