Sensor types, basic testing of output functions (digital bus test,
4-20mAtest).
4-20mAoutput: 3-wiresinkorsource,4-wire,isolated.Range0-22mA.Zeropoint
adjustableintherange4mA±0.5mA(default4mA).Uppercurrent
limitedto22mA.Loopresistance0-300ohms(witha24Vloopsupply).
Fault: 0mAnominal(0-0.5mA)
Inhibit: 1mAdefault(usercongurable1-4mA)
Warning: Userselectable.Eitheraxedlevel(3mAdefault,usercongurable
between 1-4mA), a pulsed current or disabled.
When the unit is in the warning state a gas reading can still be
calculated.
Ifthevalueofthisincreasesbeyond50%oftherstalarmlevelthe
4-20mAoutputrevertstoindicatingthegasreading.
 Ifsubsequentlythereadingdecreasesbelow25%oftherstalarm
levelthe4-20mArevertstoindicatingthewarningstate.
OverRange: 21mA
    Caution:WhencompliancewiththeATEXperformancestandardis
required the warning and inhibit current shall not be
    conguredtoavaluebetweenthan3.1mAand4.9mA.
    Note:ForOxygensensors,theoutputisarrangedsothat4mA 
    correspondsto0%V/V,and20mAcorrespondsto25%V/V.
    Theoverrangestatecanbeconguredaseitherlatchingor
non-latching. The default is non-latching.
