Description
MV5
Selection of the output signal. By pressing
or
the different output signals can be selected
EO.970
Setup of emissivity. Pressing
increases the value;
decreases the value (also valid for all
further functions). The emissivity (
e
- Epsilon) is a material constant factor to describe the ability
of the body to emit infrared energy
T1.000
Setup of transmissivity. This function is used if an optical component (protective window, addi-
tional optics e.g.) is mounted between sensor and object. The standard setting is 1.000 = 100 %
(if no protective window etc. is used).
A 0.2
Setup of average time. In this mode an arithmetic algorithm will be performed to smoothen
the signal. The set time is the time constant. This function can be combined with all other post
processing functions. On CTM-1, CTM-2, CTM-3 models the shortest value is 0.001 s (other
models: 0.1 s) and can be only increased/decreased by values of the power series of 2 (0.002,
0.004, 0.008, 0.016, 0.032, ...). If the value is set to 0.0 the display will show --- (function deacti-
vated).
P----
Setup of peak hold. In this mode the sensor is waiting for descending signals. If the signal
descends the algorithm maintains the previous signal peak for the specified time. After the hold
time the signal will drop down to the second highest value or will descend by 1/8 of the differ-
ence between the previous peak and the minimum value during the hold time. This value will be
held again for the specified time. After this the signal will drop down with slow time constant and
will follow the current object temperature.
If the value is set to 0.0 the display will show --- (function deactivated).
V----
Setup of valley hold. In this mode the sensor waits for ascending signals. The definition of the
algorithm is equal to the peak hold algorithm (inverted). If the value is set to 0.0 the display will
show --- (function deactivated).
