Operation Description
Basal display status:
When powered on, the upper display window of the instrument
shows the process value (PV), and the lower window shows the set-point (SV). This status
is called basal display status. When the input signal is out of the measurable range (for
example, the RTD circuit is broken, or input specification is set wrong), the upper display
window will alternately display “orAL” and the high limit or the low limit of PV, and the
instrument will automatically stop output.
