4.6 Clear Peak Memory (t
CLEAR
)
The integrated maximum value storage is activated when the parameter t
clear
is set to something other than “OFF” or “HOLD”.
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.
