Programming
7.3.3 Post Processing
The following parameters can be set to determine the post-processing mode.
P=5
maximum hold, hold time: 5 s
F=12.5
minimum hold, hold time: 12.5 s
G=10
averaging, average time (90%): 10 s
XY=3
advanced maximum hold, hysteresis: 3 K
XY=-2
advanced minimum hold, hysteresis: 2 K
Advanced Peak/Valley Hold with Averaging:
C=250
advanced hold threshold: 250°C
AA=15
advanced hold with averaging and averaging time (90%): 15 s
7.4 Dynamic Data
The infrared temperature is calculated 50 times a second. To request the dynamic data, following
commands are available:
?T
infrared temperature
?I
sensor ambient temperature
?XJ
internal temperature of connector (terminal type) or sensor ambient temperature
(circular type)
?Q
energy value of the infra-red temperature
?XT
trigger set point value for the FTC3 analog input
To check for resets (e.g. power shut down) use the command XI. Notice, after a reset the unit is new
initialized.
?XI
asks for the reset status
!XI0
no reset occurred
!XI1
a reset occurred, new initialization of the unit
XI=0
sets the reset status back to 0
7.5 Device Control
7.5.1 Controlling the output for the target temperature
The signal output can be set to 4 – 20 mA, 0 – 20 mA or mV. The output can provide a predefined value
of full analog range:
XO=4
output mode to 4 – 20 mA
O=25
output of a constant current at 8 mA (25% of 4-20 mA)
O=255
switches back to the temperature controlled output
7.5.2 Analog output, scaling
According to the temperature range of the model, it is possible to set the maximum voltage/current
value according to a temperature value (e.g., the maximum current (20 mA) shall represent 200°C). The
same setting is possible for the minimum value.
