OPEARTING MANUAL
EMISS 1.000 Setup of Emissivity. Pressing Up increases the value, Down decreases the value (also valid for all further functions). The
emissivity is a material constant factor to describe the ability of the body to emit infrared energy [►10 Emissivity]
TRANS 1.000 Setup of Transmissivity. This function is used if an optical component (protective window, additional optics e.g.) is mounted
between sensor and object. The standard setting is 1.000 = 100 % (if no protective window etc. is used).
AVG 0.020 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. The shortest value is 0,001 s.
If the value is set to 0.0 the function is deactivated.
HOLD Setup of signal processing. By pressing Up or Down the mode can be selected.
PEAK: 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 difference
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 t
emperature. If the value is set to 0.0 the display will show --- (function deactivated).
VALL: Setup of Valley hold. In this mode the sensor waits for ascending signals. The definition of the algorithm is
according to the peak hold algorithm (inverted). If the value is set to 0.0 the function deactivated.
APEAK (Advanced Peak Hold): In this mode the sensor waits for local peak values. Peak values which are lower than their
predecessors will only be taken over if the temperature has fallen below the Threshold value beforehand. If
Hysteresis is activated a peak in addition must decrease by the value of the hysteresis before the algorithm takes it
as a new peak value.
AVALL (Advanced Valley Hold): This mode is the inverted function of Advanced Peak hold. The sensor waits for local
minima. Minimum values which are higher than their predecessors will only be taken over if the temperature has
exceeded the Threshold value beforehand. If Hysteresis is activated a minima in addition must increase by the
