You can adjust this value between 200 ms and 100 s. Minimum and maximum value get
detected in two data storages. The storages get deleted alternately after the adjusted time. The
not-deleted storage keeps its value for one more cycle time. Breaking downs of the measuring
value are avoided in this way.
Adjustment at pyrometer:
min
Option minimum storage value
The lowest measured value is stored, so the digital display and the current output get frozen at
the last measured minimum value. The minimum value storage is not available in operating
mode “auto”. To detect the minimum the delete time must be at least a triple of the response
time.
Adjustment at pyrometer:
max
Option maximum value storage
The highest measured value is stored, so the digital display and the current output get frozen at
the last measured maximum value. To detect the maximum the delete time must be at least a
triple of the response time.
Adjustment at pyrometer:
auto
Mode for discontinuous measurement problems.
Hereby e.g. moving parts are measured just in the moment of their passing of the pyrometers
measuring field. The maximum temperature of the part is registered and saved. The minimum
level of the sub temperature range is set as the temperature bar. With every culmination of this
threshold the former value is deleted. The minimum level of the sub temperature range has to
be exceeded by at least 1 % or 2 °C for the deletion to be carried out. For the sub temperature
range being equivalent to the temperature range, the memory is erased if the minimal level of
the temperature range is exceeded.
Adjustment at pyrometer:
external
If the maximum value storage at the pyrometer is set to external, it can be deleted via the
external pin or via software. Pin J serves as input for the external deletion. To delete the
maximum value storage, pin J must be connected shortly to the power supply (pin K, +24 V
DC). Please refer chapter Connecting the pyrometer, on page 31.
To delete the maximum value storage via software PYROSOFT Spot or PYROSOFT Spot Pro
(optional), use the button DELETE in register PARAMETER.
Analogue output
The scale of the current output can be switched from 0 ... 20 mA to 4 ... 20 mA with this
parameter. Please consider the signal input of your evaluation device.
Formula for calculation of the temperature out of the current value
read current value in mA
lower current value 0 or 4 mA
upper current value 20 mA
start of (sub) temperature range in °C
end of (sub) temperature range in °C
(sub)temperature range in °C
Example: DT 4L –40 °C to 1000 °C, read value Iist= 8 mA, Imin = 4 mA
