OPEARTING MANUAL
Selection of the Output signal. By pressing Up or Down the different output signals can be selected (see table).
MV5
E0.970 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].
Setup of Transmissivity. This function is used if an optical component (protective window, additional optics e.g.) is mounted
T1.000
between sensor and object. The standard setting is 1.000 = 100 % (if no protective window etc. is used).
Setup of Average time. In this mode an arithmetic algorithm will be performed to smoothen the signal. The set time is the time
A 0.2
constant. This function can be combined with all other post processing functions. On 1M/ 2M/ 3M models the shortest value is
0,001 s (other models: 0,1 s) and can be increased/ decreased only 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 deactivated).
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 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
temperature.
If the value is set to 0.0 the display will show --- (function deactivated).
Setup of Valley hold. In this mode the sensor waits for ascending signals. The definition of the algorithm is according to the
V----
peak hold algorithm (inverted).
If the value is set to 0.0 the display will show --- (function deactivated).
