Paperless recorder parameters
In order to test the isolation voltage of two adjacent thermocouple wires, we connect the ground wire of the withstand voltage machine and the ground wire of the pressure measuring device to a thermocouple together;
At the other sampling end, the positive wire of the withstand voltage machine is connected to the test end of the other thermocouple, and the positive wire of the pressure measuring device is manually measured at the connection terminal of the thermocouple.
The voltage measured in this way is the isolation voltage of the two thermocouple wires.

After all the equipment is turned on and the voltage of the withstand voltage machine is adjusted to 1200V, we can clearly monitor that the equipment is working normally, and the data collected by TP1000 through the 1704 acquisition module is stable.
The data curve interface is also stable, indicating that the high voltage has not affected the normal operation of the equipment.
