D Term . . . . . . . . . . . . . . . . . . . . . . . The derivative term causes the loop to
respond quickly to changes. Use 0 or a very
small value to avoid oscillations.
Name . . . . . . . . . . . . . . . . . . . . . . . . It may be helpful to give an output a more
meaningful name—perhaps the material
being deposited or the evaporation supply
being controlled.
3.4 Edit: Recorder Mode
When Recorder mode is selected for an output, the output is not controlled by the
PID loop. Instead, the output supplies a voltage that is proportional to an input
value.

Input. . . . . . . . . . . . . . . . . . . . . . . . . Selects the sensor, analog input, or control
output that is being measured. Only one
input can be selected.
Output . . . . . . . . . . . . . . . . . . . . . . . The recorder output voltage can vary from
0 V to +/-10 V. Output (Full Scale) establishes
the measured value on the Input that will
generate a Full Scale (+/-10 V) output. In the
sample above, a measured rate of 10 Å/s will
generate a 10 V recorder output. If you select
1000 kÅ, then a measured thickness of 1000
kÅ will generate a 10 V output to the
recorder.
