Switch off DTA and re-power it.

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

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.

Clear the user’s settings. Function address = 4724; Write data = 1234

(Please DO NOT modify this value; otherwise system confusion may occur.)

Switch off DTA and re-power it.

The model adopted in this example is: DTA4896R1 with firmware V3.50.

After the above procedures are completed, DTA will display the information on the left hand side, representing that DTA has return to default settings successfully.

Return to default value. The default sensor is PT100, which will be displayed when DTA is not connected to a sensor or thermocouple.
