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

ATD function (Only available in pyrometer with ATD function)
Select and activate one of these memory modes for Spectral Channel 1
(L1) and configure as described below. The calculated temperature value
can be shown on the rear panel display and/or transmitted to the current
output for further processing.
Min/Max Memory
In this mode
—also called peak picker—the pyrometer determines the
highest or lowest temperature reading and keep the temperature read-
ing. As an option, one of the switching inputs can be configured to reset
the min/max memory and to define the smoothing filter setting.
Double Maximum Memory with hold time
It might often be desirable to determine the peak temperature during a
defined time period, for example when the objects to be measured move
past the pyrometer, resulting in temperature readings which would ap-
pear to be cyclical. In this mode, the displayed temperature reading will
