PV SV Status of the temperature controller
Default value
Press “down” key continuously until the value reaches 1357
(please DO NOT modify this value; otherwise system confusion
may occur).
＋Press the two keys together once to return to main screen.
Main screen
Switch off DTA
and re-power it.
Return to default value. The default sensor is PT100, which will be
displayed when DTA is not connected to a sensor or
thermocouple.
The model adopted in this example is: DTA4896R1 with firmware V3.50.
1. Make sure RS-485 hardware communication cable in DTA has been connected to the computer.
2. Make sure the communication parameters in DTA are consistent with those in the computer.
