If the maximum value storage is switched on, the highest last temperature value will always be
displayed and stored. As such, it may be beneficial to periodically clear and reset the stored
maximum values in order to obtain new temperature readings.
This storage also has to be cleared at regular intervals when fluctuating object temperatures
cause the display or the analog outputs to change too rapidly or when the pyrometer is not
constantly viewing an object to be measured.

4.6.1 Single and Double Storage Modes

Depending upon the selected settings, the maximum value storage will either work in single

storage mode or in double storage mode.
Single Storage

Mode:

Single storage mode is used when you want to reset the stored value using
an external impulse via one contact closure from an external relay (such as
between two measured objects). The relay contact is connected directly to
the pyrometer between pins J and K. This mode allows a new value to be
established after each impulse from the reset signal. Single storage mode

also comes into effect when the Clear Peak Memory t

clear

is set to AUTO.

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.

4.6.2 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. The values are immediately cleared from the storage by contacting
the wires connected to pins J and K, if the EXTERN mode was selected.
