18.4.4 Post Processing

The following parameters can be set to determine the post processing mode. See section 8.5
Processing, page 50.
P=5.0 peak hold, hold time: 5 s
F=12.5 valley hold, hold time: 12.5 s
G=10.0 averaging, average time (90%): 10 s
XY=3.0 advanced peak hold, hysteresis: 3 K
XY=-2.0 advanced valley hold, hysteresis: 2 K
Advanced Peak/Valley Hold with Averaging:
C=250.0 threshold: 250°C
AA=15.0 averaging time (90%): 15 s
18.5 Dynamic Data
All temperature related information is calculated multiple times per second. To request the dynamic
data, the following commands are available:
?T target temperature
?I internal temperature of the sensing head
?XJ internal temperature of the electronics housing
?Q energy value of the infrared temperature
?XT trigger set point (active/inactive) for the FTC3 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
18.6 Device Control
18.6.1 Output for the Target Temperature
The signal output can be set to 4 – 20 mA, 0 – 20 mA or V. If current output is activated, the output can
provide a predefined current:
XO2O=4 mode to 4 – 20 mA for output 2
O2O=13.57 output of a constant current at 13.57 mA at output 2
O2O=60 switches back to the temperature controlled output
18.6.2 Analog Output, Scaling
According to the temperature range of the model, it is possible to set a maximum voltage/current
value according to a temperature value (e.g., the maximum current 20 mA shall represent 200°C /
392°F). The same setting is possible for the minimum value.
H2O=500 the maximum current/voltage value for output 2 is set to 500°C
L2O=0 the minimum current/voltage value for output 2 is set to 0°C
Remark: You cannot set this value for thermocouple output. The minimum span between the
maximum / minimum settings is 20 K.
