Parameter Meaning
Lead compensation resistance
This value is used to compensate the resistance of the probe lead and is de-
pendent on the lead length.
For best temperature measurement results, the resistance value of the
probe lead has to be entered here (with short-circuited probe).
A
If the total resistance at the measurement input (sensor resistance +
selected value for OF.r) exceeds 320
Pt1000/KTY2x-6, a measurement error will occur !
Unit
for the process value displayed
A
Only the process value at the measurement input will be
correspondingly converted when changing over to °F.
All other variables will retain their values.
Filter time constant
for adapting the digital input filter.
At a signal step, 63% of the changes are registered after the filter time con-
stant has elapsed.
Values between 0.1 and 0.7 are interpreted as 0.8 (sampling time).
If the filter time constant is long:
- high damping of interference signals
- slow reaction of the process value display to process value changes.
