<div dir="auto">Hi Bob,</div>
<div dir="auto"><br>
</div>
<div dir="auto">I have a question about the gas control system. When the alert gas set point is set to 90 mbar, what is that relative to in order to provide stable absolute pressure?</div>
<div dir="auto"><br>
</div>
<div dir="auto">Also, the ambient pressure readout appears to not change and is at a value of 1017.54.</div>
