Result var.:
"Bolt YP T" and "Bolt YP A".
Alarms:
Yield torque high (YTHM). If "Bolt YP T" > YTH
Yield torque low (YTLM). If "Bolt YP T" < YTL
Yield angle high (YAHM). If "Bolt YP A" > YAH
Yield angle low (YALM). If "Bolt YP A" < YAL
Trace
:
YAH and YAL are shown in trace as vertical infinite lines. YTH and YTL are shown in trace
as horizontal lines from monitoring stat to monitoring stop. The lines are only shown when
Torque vs. Angle is selected and Monitoring limits are enabled in the trace form (see
View of trace curves).
