7.4
Temperature sub range
You have the opportunity to choose a sub range (minimum span 51°C)
within the basic measuring range of the pyrometer. This sub range corre-
sponds to the analog output (4 to 20 mA).

Clear time t
CL
for maximum value storage
The maximum value storage stores the highest measurement value. The
clear time defines the time period until the stored value is deleted and
replaced by a new one.
The following settings are possible:
Clear time Off: The storage is switched off and only momentary values
are measured.
If any clear time is set the maximum value storage will be cleared at this time.
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 has to be indicated. In this 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 when the temperature of the new
hot object exceeds the low limit of the sub range by 1% or at least 2°C.

with HT 6000
(accessory)
The HT 6000 is a portable battery driven instru-
ment for the pyrometer parameter settings and
indication of temperature.
The pyrometer has to be connected to the HT
6000 via its service interface cable with the fe-
male SUB-D connector. When the HT 6000 is
switched on it recognizes the pyrometer auto-
matically and the preset parameters can be
displayed. With the “
PAR
” button the different
parameters can be called. With the arrow buttons
and
the values of the parameters can be
selected and confirmed with the “
ENTER
”
button.
If no button is pressed for 30 s the HT 6000
changes to the temperature indication
without
accepting the changed value
