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
these fluctuations on the yielded temperature reading. The pyrometer's
response time is proportional to the time constant. Set for example signal

Min/Max Data
PA pyrometer features data memory to store minimum and maximum
(peak) temperature readings. This feature can be configured in one of
the following modes:
 Memory off
 Store minimum value (single)
 Store maximum value (single)
 Store double max. value for cyclical processes
 Double peak picker combined
 Automatic temperature detection (ATD) function (Only available in
pyrometer with ATD function)
Select and activate one of these memory modes for Quotient, Lambda 1
(L1) or Lambda 2 (L2) and configure as described below. The calculated
