Double Storage
Mode:
Double storage mode comes into effect when selecting one of the reset
intervals. This mode utilizes two memories. With the first memory, the
highest measured value is held and is deleted alternately in the time
interval set (clear time). The other memory retains the maximum value
throughout the next time interval. The disadvantages of fluctuations in the
display with the clock frequency are thereby eliminated.
Note:
The maximum value storage setting coincides with adjustments made to the
response time.
The response time setting (working like a low-pass filter) is applied first. After that,
the maximum storage is processed. So when using both, the maximum storage takes
the peak of the signal that was previously smoothed by the response time filter.

4.5.2 Clear Time Settings
The following settings are available through the InfraWin software or by using the UPP data
format commands.
OFF When set to OFF , the maximum value storage is switched off and all new
temperature values are measured but not stored.
0.01s…25.0s
If the clear time is set between
0.01 s and 25.0 s
, the maximum value is
held in double storage mode. After the entered time, the value will be
cleared alternately from one of the storages, while the value of the other
storage is shown.
EXTERN With the external clearing function, the storage operates in single storage
mode. External clearing is only possible via software.
AUTO The AUTO mode is used for discontinuous measuring tasks. For example,
when objects are being transported on a conveyer belt and pass the
measuring beam of the pyrometer only for a few seconds. In this case, the
maximum value for each object has to be obtained.
With the
AUTO mode, the maximum value is stored until a new hot object
appears in the measuring beam. The temperature, which has to be
recognized as “hot” is defined by the low limit of the adjusted sub range.
The stored maximum value will be deleted once the temperature of the new
hot object exceeds the low limit of the sub range by 1% (transition in
positive direction) or by at least 2 °C. This is also valid if the sub range equals
the basic range.
4.6 Analog Output
The analog output has to be selected according to the signal input of the connected instrument
(controller, PLC, etc.). If 4 to 20 mA is set, the analog output gives 4mA for temperatures below
lower range limit.
Note:
Settings for Analog Output : 0 to 20mA or 4 to 20mA
