PEA The Peak feature stores the highest input the control has measured
since the last reset or Power On. At Power On PEA is reset to the
present input. To manually reset the value PEA must be in the lower
display. Press the ENTER key to reset. PEA will be reset and display
the present input value.
UAL The Valley feature stores the lowest input the Instrument has
measured since the last reset or Power On. At Power On UAL is reset
to the present input. To manually reset the value UAL must be in the
lower display. Press the ENTER key. UAL will be reset and display
the present input value.
InPC Input Correction: Select ±500 °F, °C, or counts. This feature
allows the input value to be changed to agree with an external
reference or to compensate for sensor error. Note: InPC is reset
to zero when the input type is changed, or when decimal position
is changed.
FiLt Digital Filter: Select OFF, 1 to 99. In some cases the time constant
of the sensor, or noise could cause the display to jump enough
to be unreadable. A setting of 2 is usually sufficient to provide
enough filtering for most cases, (2 represents approximately a 1
second time constant). When the 0.1 degree resolution is se-
lected this should be increased to 4. If this value is set too high,
controllability will suffer.
POL (Option 934, 936, Analog Retransmission Output) Process Out-
put Low: Select -450°F, -260°C, or -1999 counts to any value less
than POH.
