Extern: The external clearing of the storage can be activated and used within an own software
(see Chapter 9 Data format UPP (Universal Pyrometer Protocol)) or via an external contact (for
connection see 3.1.1 Pin assignment for the connector on the back of the pyrometer ). In
this case, the storage operates only in single storage, because only a single deletion mechanism
is used.
Auto:
The
auto
mode is used for discontinuous measuring tasks. For example, objects are
transported on a conveyer belt and pass the measuring beam of the pyrometer only for a few
seconds. Here the maximum value for each object must be indicated. In this mode the maximum
value is stored until a new hot (or cold) object appears in the measuring beam. The temperature
which must be recognized as
hot is defined by the low limit of the adjusted sub range. The
stored maximum value will be deleted when the temperature of the new hot object exceeds the
low limit
from of the sub range by 1% or at least 2 °C. If a lower limit is not entered, the
maximum value storage will be deleted whenever the lower level of the full measuring range
has been exceeded. The
minimum value function operates in the opposite manner. The
minimum value stored will be deleted when the upper limit of the set range is below it by 1%
(at least 2 °C). If an upper limit is not entered, the minimum value stored will be deleted
whenever it drops below the upper level of the full measuring range.
Note:
In the command structure, the maximum storage comes after the exposure
time. This results in:
•
clear time
≤
the adjusted response time is useless
•
clear times must be at least 3 times longer than the response time
•
only maxima with full maximum value can be recorded, which appear at
least 3 times longer than the response time.
5.2.2 Subrange
You can choose a sub range (minimum 51 °C) within the basic measuring range of the
pyrometer. This sub range corresponds to the analog output. The lower value (0 or 4 mA)
describes the beginning of this measuring range, the upper value (20 mA) the end of the range.
With a sub range, it is possible to fulfill the requirements of the “auto” clear mode of the
maximum value storage (see above).
5.2.3 Baud rate (kBaud)
The transmission rate of the serial interface in Baud (Bd) is dependent on the
length of the cable. A standard cable length with RS232 for 19200 Bd is 7 m,
with RS485 2 km. The baud rate is reduced by 50% if the transmission
distance is doubled.
