Temperature offset using linear interpolation
When necessary, PA pyrometer allows you to program an offset for the
temperature reading reported. The offset correction can be configured
individually with a minimum of 2 and a maximum of 10 interpolating
points (X/Y nodes). This information is stored in a user-defined tempera-
ture-indexed lookup table and used for signal conditioning. For values
lower than the 1st node and higher than the last node, the first and last
linear segments are extrapolated. Enter the nodes in ascending order.
Use the rear panel display to access this function via C001 / LIN.1.
Signal Smoothing Filter
When the target object’s temperature is erratic, it makes sense to
smooth these temperature fluctuations in order to stabilize the signal.
The greater the time constant t
98,
(user definable), the lower the effect of
these fluctuations on the yielded temperature reading. The pyrometer’s
response time is proportional to the time constant. Set signal smoothing
via parameter C001 / FIL.1
Models PA 10/13 which have a thermopile sensor also feature „automat-
ic averaging“. This facilitates a steady measurement, on the one hand,
and enables fast response times on the other hand when temperatures
becomes erratic. This function is activated as a default setting.
