Values listed under each gas type are in volts.
Note: By design, these values are identical to the outputs from Brooks Automation, Inc. / Granville-Phillips®
Convectron® gauges, Mini-Convectron® modules and controllers so that equivalent units can be interchanged
without affecting your process system or software.
An analog output of 10 volts indicates a faulty convection gauge or unplugged gauge cable.
