3.5 Changing Thermocouple Input Type (Model CTXL-DTC)
The dual thermocouple input model CTXL-DTC can accommodate J, K, or T
thermocouple types. The factory default setting is Dual K type thermocouple
input. You can configure the recorder for other thermocouple types (J or T) from
the PC without re-calibration as follows:
Once the PC is connected to the recorder thru RS232 cable, use the following PC
commands (in Bold):
Command Description Example
IT0 Change to K Type TC IT0; Toggle Power to use new input type
IT1 Change to J Type TC IT1; Toggle Power to use new input type
IT2 Change to T Type TC IT2; Toggle Power to use new input type
After issuing the command, the response is “Toggle Power to use new input
type” which means to remove and then apply power to the recorder for the
command to take affect. At the power up, the LCD screen always shows the
thermocouple type for two seconds. This is the way to confirm thermocouple
input type.
3.6 Changing Process Voltage Input Range (Model CTXL-DPR-V)
The dual process voltage input model CTXL-DPR-V can accommodate 0-1V,
0-5V and 0-10V input range. The factory default setting is 0-5V voltage input.
You can configure the recorder for other voltage input range (0-1V, 0-10V) from
the PC without re-calibration as follows:
Once the PC is connected to the recorder thru RS232 cable, use the following PC
commands (in Bold):
Command Description Example
IP0 Change to 0-5V IP0; Toggle Power to use new input type
IP1 Change to 0-1V IP1; Toggle Power to use new input type
IP2 Change to 0-10V IP2; Toggle Power to use new input type
After issuing the command, the response is “Toggle Power to use new input
type” which means to turn off recorder and then turn it on for the command to
take affect. At the power up, the LCD screen always shows the voltage input
range for two seconds. This is the way to confirm volatge input range.
